Indianapolis Metro Area Housing Affordability Report: January 2023
The cost of housing in the Indianapolis metro area has made it a more expensive place to live. Since 2015, the price of housing in the Indianapolis metro area has exceeded the U.S. average. Significant fluctuations in demand during the pandemic, coupled with a growing supply shortage due to lagging development, have created the conditions for a tight housing market. Mortgage interest rates have also climbed from their 30-year historic lows, increasing costs on the purchase of a home. Although rising rates may provide some relief in terms of demand for housing, permitting for new housing units is also falling and actual home completions will decline as a result.
This report analyzes trends in housing affordability between 2005 and November 2022 (the most current permitting data) and estimates whether there is a deficit or surplus of housing units across the following counties in and around the Indianapolis metro area: Boone, Hamilton, Hancock, Hendricks, Johnson, Madison, Marion, Morgan, Putnam, and Shelby. Data sources used and their most recently availability include: the American Community Survey (2021), U.S. Department of Housing and Urban Development (November 2022), the National Association of Homebuilders (2020), S&P CoreLogic Case-Shiller Home Price Indices (3
rd Quarter 2022), Zillow (December 2022), and the Indiana Business Research Center (2022). The housing deficit/surplus in 2022 is estimated using forecasts of county populations, average household sizes, and permitting data. It is important to note that the housing unit deficit/surplus estimates may change upon each new data update and release.
KEY FINDINGS
- The housing deficit in 2022 is in the range of 18,852 to 61,238. To meet population growth by 2028 and close the housing deficit, between 66,000 and 115,000 housing units will need to be built.
- Due to elevated prices and rising interest rates, the affordability of purchasing a home in the Indianapolis metro area is near its lowest point in more than 15 years. In just the past 8 years, the cost of purchasing an average-price home has increased by a range of 61% to 88%; much of that increase occurred over the last two years.
- Marion and Madison Counties have experienced the largest decreases in affordability over the last 8 years: 88% and 86% respectively.
- In Madison County, 92% of permits issued between 2012 and 2022 were for single-family housing units. Eight percent of permits were for multi-family structures and 71% of those were for structures with five or more units.
- Marion County is running the largest deficit of housing unit permits. In 2022, its housing permit deficit was 3,065 units.
- Hamilton County has the largest surplus of housing unit permits. In 2022, the county ran a surplus of permitted housing units between 718 and 1,920.
- Household incomes have not kept pace with rising housing costs. Between December 2015 and December 2022, the average hourly wage increased by 28% from $23.00 to $29.34. However, due to the rapidly increasing cost of housing, the number of hours of work required to cover the median mortgage payment increased from 30 hours (about one and a quarter days) to 58 hours (about two and a half days), a 95% increase, as seen in Table 4.
- Between 11,050 and 19,301 permits are needed annually through 2028 to close the housing supply deficit in the Indianapolis MSA (Metropolitan Statistical Area) and meet the demands of future population growth. Projected permitting for new housing in 2022 started off well, but it is tapering off as home builders reassess the demand for housing in a higher interest rate environment. From 2005 to 2021, the average annual permitted units issued was 8,765. This historical average is 45% to 79% of what is needed to close the deficit and meet new housing demand by 2028. Based on permit data through October 2022, counties with supply deficits are projected to issue 12,861 permits, which is not enough to close the deficit plus new housing demand by 2028. To avoid a collapse in new home building similar to the one that followed the last recession, permitting must remain at elevated levels for the next several years.
- Permits in the Indianapolis metro area are increasingly shifting away from single-family homes to multi-family structures. In 2012, the mix was 80% single-family/20% multi-family. In 2022, the mix was 63% single-family/37% multi-family.
- Homebuilder confidence has declined by 65% since a recent high in November 2020. The National Association of Home Builders/Wells Fargo Housing Market Index (HMI) is based on a monthly survey of NAHB members designed to take the pulse of the single-family housing [i] The index can range between 0 and 100, 0 being the lowest confidence and 100 the highest confidence. In December, the NAHB/Wells Fargo Housing Market Index for the Midwestern region was 30, having fallen for 9 straight months from 91, indicating a decrease in homebuilder confidence and a subsequent decrease in new housing going forward.
DECLINING AFFORDABILITY AS MEASURED BY THE HOMEBUYER MISERY INDEX
The “Indianapolis Metro Area Homebuyer Misery Index,” developed by the Common Sense Institute, captures the impact of housing prices and mortgage rates on the affordability of purchasing a new home. The metro-area Homebuyer Misery Index is based on 30-year mortgage rates and Zillow home prices for the counties under consideration.
The mortgage rates are converted into an index with 2005 as its base year. 2005 is the base year due to the availability of home price data from Zillow. The mortgage rate index is then added to the Zillow home price index and normalized. The following graph shows the Indianapolis Metro Area Homebuyer Index based on ten counties versus the U.S. Homebuyer Misery Index. The Indianapolis Metro Area index closely tracks changes in the U.S. Homebuyer Misery Index over time. The substantial increase in both indices from 2012 to the end of 2020 was primarily a function of home prices increasing. Beginning in 2021, home prices went up dramatically and mortgage rates more than doubled by October 2022, consequently the cost to purchase an average priced home went up by 58%. In the last two months of 2022, the misery indices have declined as home prices and mortgage rates have fallen.
The county indices must be viewed as measuring the changes in affordability for each county in isolation and not relative to overall affordability. For example, home prices are highest in Hamilton and lowest in Shelby, but the largest change in affordability has occurred in Madison County. The significant increase in the index value over the last two-and-a-half years reflects a large decrease in home affordability. CSI shows the ten counties relative to each other and the U.S. in two graphs. The first graph shows those counties whose indices were generally above the U.S., and the second graph shows the counties whose indices were below the U.S. The graphs are useful for evaluating and comparing trends in each county to each other and the U.S., but to determine the degree to which a county became more or less affordable relative to the others, the change in the indices must be calculated between two points in time as we have done in Table 1. As shown in the following graph, over the last two years, the indices for Hamilton, Hancock, Hendricks, Johnson, and Marion counties were higher than the U.S. Homebuyer Misery Index, with Marion the clear outlier since at least 2012.
The graph below shows the counties whose indices are below the U.S. Homebuyer Misery Index since 2005, these include Boone, Madison, Morgan, Putnam, and Shelby Counties.
Separate graphs of each county’s Homebuyer Misery Index compared to the national Misery Index and the Case-Shiller Index for the Indianapolis MSA can be found in Appendix A.
The change in affordability as of December 2022 relative to January of the previous eight years is shown in
Table 1. For example, in Marion County, since January 2014, the cost to purchase an average-price home rose by 88%. Home affordability has declined in all ten counties since 2014, but most of the decline has come after 2020. Since May of this year, home prices have leveled off or decreased slightly but affordability has continued to worsen as mortgage rates have increased. Marion County experienced the largest change in affordability in the Indianapolis metro area. In addition to Marion, Madison, Johnson, Hendricks, and Hancock Counties all exceeded the U.S. for decreases in affordability. Boone, Hamilton, Morgan, Putnam, and Shelby Counties experienced slower declines in affordability.
[table id=56 /]
The following chart shows the average change in affordability for the ten counties combined for every year going back to 2014 through December 2022. Nearly 40% of the change has occurred since January 2022 and 75% has occurred since the beginning of 2021.
Changes in affordability
The Wall Street Journal and Realtors.com began producing their Emerging Housing Markets Index in spring 2021 and has now published six quarterly estimates. The index identifies the top metro areas for home buyers seeking an appreciating housing market, strong local economies, and appealing lifestyle amenities. Three hundred of the most populous core-based statistical areas as measured by the U.S. Census Bureau are evaluated using two principal areas: real-estate markets (50%) and economic health (50%). It utilizes eleven key indicators that are weighted and summed to create a single measure: real-estate supply (16.6%), real-estate demand (16.6%), medium home listing price trend (16.6%), unemployment (6.25%), wages (6.25%), regional price parities (6.25%), amenities (6.25%), small businesses (6.25%), and property taxes (6.25%).

Table 2 shows the rankings of the Indiana core-based statistical areas relative to all three hundred most populous areas included in the index. Note that these are cities as opposed to counties. The Indianapolis-Carmel-Anderson MSA is in the lower half of all metro areas in terms of future home price appreciation. This index provides some perspective that while housing affordability is near record lows, as of the latest data from fall 2022, Elkhart-Goshen, Fort Wayne, and Lafayette-West Lafayette are ranked in the top ten housing markets and are viewed as attractive given the potential for prices to continue to rise and for other quality of life amenities and economic factors.

HOME PRICES
The following graph shows home price indices for ten counties based on Zillow prices as well as the S&P/Case-Shiller Home Price Indices for the United States and the Indianapolis MSA. Home prices in the Indianapolis metro area increased by 83% since 2013 and 53% between the beginning of the COVID-19 pandemic and December 2022. Since mid-2022, home price growth the Indianapolis metro area has begun to taper off after continually increasing since 2012. Nationally, home prices increased by 48% between the beginning of the COVID-19 pandemic and December 2022 and have declined by 1.1% since May 2022.
Table 3 shows the average home prices in the ten counties in this study and the U.S. overall. Among the metro counties, Hamilton is ranked 1st (highest average price) and Madison is 10th (lowest average price). Only Boone and Hamilton counties are more expensive than the U.S. average. An important assumption for estimating a housing surplus/deficit is that a resident that cannot afford a housing unit in their current county cannot afford one in a more expensive county.
HOURS OF WORK NEEDED TO AFFORD A HOME MORTGAGE
To measure the impact on the average homeowner in the Indianapolis metro area, Common Sense Institute (CSI) calculated the number of hours that one would have to work while earning the average hourly wage in December from 2013 to 2022 to cover the monthly mortgage payments shown in Table 4. Over just the last 12 months, driven primarily by the increase in mortgage rates, an additional 22 hours of work per month has become necessary to cover the mortgage on a newly purchased average-price home.
[table id=59 /]
The graph below shows the evolution of monthly mortgage payments on an average-price home and the required hours of work necessary to cover the payment. Required hours fluctuated around 28 from January 2007 until the summer of 2020, after which it increased dramatically as home prices rose. Beginning in the spring of 2022, mortgage rates have increased as the Federal Reserve addresses inflation. Since the start of the pandemic in December 2019, the hours of work required to afford a mortgage on an average-price home increased by 76% from 33 hours to 58 hours (about two and a half days). In the last two months of 2022, home prices and mortgage rates declined, reducing the hours required to work to pay the mortgage on an average-price home.
INDIANAPOLIS METRO AREA HOUSING SUPPLY SHORTAGE
The Indianapolis metro area has failed to build enough housing to keep pace with demand. Standard housing market reports like those developed by the National Association of REALTORS® track inventory based on homes listed for sale. What those reports do not capture is the total stock of homes needed to maintain a healthy housing market. A healthy housing market is one that has sufficient inventory to maintain efficient vacancy rates, prevent overcrowding and cost burdening, and accommodate demolitions and replacements over time.
CSI estimates the number of homes in ten counties in and around the Indianapolis metro area needed to achieve a healthy housing market under two scenarios. Each scenario is intended to measure the difference between the actual number of homes in a county and the number of homes needed to maintain a healthy market for the local population. The first scenario calculates a housing deficit or surplus based on a low estimate of homes held off the market for purchase by the local population. The second scenario calculates a housing deficit or surplus based on a high estimate of homes held off the market.
Housing units and households – Each scenario uses estimates of housing units and households from both the U.S. Census Bureau’s American Community Survey (ACS) and the Indiana Business Research Center. We adjust the housing units by removing those that are considered uninhabitable by virtue of having no kitchen or plumbing.
Homes held off the market – Total homes held off the market is the number of existing housing units not available for purchase. The estimate includes a range of second homes at the county level released by the National Association of Homebuilders
[iii] and an estimate of uninhabitable homes from ACS.
Table 5 shows the range of NAHB estimates of the share of housing stock allocated to second homes. All counties apart from Putnam have between 0% and 4.99% of the housing stock allocated to second homes. Putnam county has a range of 5% to 10%.
[table id=60 /]
Desired ratio of total units to local population – To estimate the target number of housing units, the value of 1.1 housing units per household was used to represent a healthy market. This value is derived from the historic average ratio of vacancy rates in the U.S. and was the basis for a housing supply report done for the state of Oregon.
[iv] Table 6 shows the forecasted change in population and the number of households in 2028 and 2033.
[table id=61 /]
Using the scenarios discussed above, the deficit in housing units in 2022 is estimated to have been between 18,852 and 61,328 units.
Table 7 presents summary results for the ten counties in the Indianapolis metro area considered in this study. CSI will continue to monitor new data as it becomes available and will amend the estimates and methodology as required.
[table id=62 /]
BUILDING PERMITS AND THE HOUSING SUPPLY DEFICIT
The housing supply deficit dropped between 2005 and 2012 and then began to accumulate through 2022 as the population continued to increase (see the following graph). At the same time, even though the number of housing unit permits increased, not enough were issued to close the housing deficit.
Appendix B provides an equivalent graph for all ten counties.
To erase the estimated statewide deficit and meet new population-driven demand for housing by 2028, an additional 66,299 to 115,803 permitted units are required in total (11,050 to 19,301 per year). CSI tracks building unit permits by county on a quarterly basis to evaluate whether the level of issuance is sufficient to close the existing housing deficit and meet new demand for housing.
See
Table 8 to see the scenario estimates for each of the ten counties included in this study.
[table id=63 /]
To erase the estimated statewide deficit and meet new population-driven demand for housing by 2033, an additional 107,676 to 153,639 permitted units are required in total, equating to 9,789 to 13,967 per year (see
Table 9). Closing the deficit and meeting new housing demand by 2033 requires fewer permits per year than does closing the deficit by 2028, because erasing the 2022 deficit is spread out over an additional five years.
[table id=64 /]
Under scenario 1, based on the permitted unit data through November 2022, six counties, Hamilton, Hancock, Madison, Marion, Morgan, Putnam, and Shelby are on track to issue enough permitted units to close the 2022 housing deficit and meet new housing demand by 2028. Under scenario 2, only Hamilton, Hancock, Madison, and Morgan Counties are on track to issue enough permitted units to do so.
Some counties with housing deficits are consistently issuing enough annual new building unit permits to address local deficits and future housing needs, but these surplus permits do not help alleviate deficits in other counties. In many counties where there are housing deficits, not enough new building unit permits are being issued to cover current deficits let alone new housing demand. Should this continue, the housing supply deficit will continue to grow. The assumption behind this is that surplus houses in one county cannot be moved to counties with deficits and households will not relocate from deficit counties to surplus counties.
The following graph shows the average number of needed housing unit permits in deficit counties required to close the deficit by 2028 for 2 scenarios, and the number of permits issued monthly so far. The red line shows the average monthly required permits to close the 2022 deficit and meet new housing demand by 2028 for scenario 1. The blue line is for scenario 2. In scenario 1, enough permits have been issued in seven months over the first eleven months of 2022 to cover the housing deficit and meet new demand for housing by 2028. However, permitting is trending down as high interest rates are dampening demand for housing and builders are applying for fewer permits. In scenario 2, enough permits were issued in only one month, April. After April, insufficient permits have been issued to close the deficit and meet new housing demand by 2028. The number of permits issued in deficit counties varies between scenario 1 and 2 because under scenario 2, more counties have supply deficits. Therefore, we are tracking the permits in the additional deficit counties.
Appendix C provides an equivalent graph for all ten counties.
TYPES OF PERMITS ISSUED
Table 10 shows the number of housing unit permits issued in total and by type for the Indianapolis metro area from 2012 through November 2022. Annual permitted units issued has increased from 5,026 in 2012 by 162% to 13,192 in 2022. The share of permitted single-family units issued has gone from 80% in 2012 down to 63% in 2022. The share of permits for multi-family structures has increased from 20% in 2012 to 37% in 2022. 35% of all permitted units are for structures with five or more units. The number of annual permits issued from 2012 through 2022, by county and type, are shown in
Appendix D.
Note: Percentages in multi-family subcategories may not always add up to the total for all multi-family structures due to rounding.
[table id=65 /]
GOING FORWARD
As shown in the following graph, as mortgage rates (red line) have increased since March 2022, demand for housing has begun to taper off. In response, many home builders are re-evaluating their plans for new housing. The November Housing Market Index (HMI) (blue line) released by the National Association of Homebuilders, which reflects builder confidence in the market for newly built single-family homes, fell for the 10th straight month to its lowest point since April 2020.[v]
The housing deficit remains and, if builders reduce annual production, which looks increasingly likely based on the HMI, it will not decrease. If population growth continues as forecasted, absent sufficient new housing units, the deficit will grow. Developers might consider changes to the mixture of housing they build, transition to building higher-density and less expensive housing so that the deficit can be erased even in a high interest rate environment.

[i] The NAHB/Wells Fargo HMI is a weighted average of three separate component indices: Present Single-Family Sales, Single-Family Sales for the Next Six Months, and Traffic of Prospective Buyers. Each month, a panel of builders rates the first two on a scale of “good,” “fair” or “poor” and the last on a scale of “high to very high,” “average” or “low to very low”. An index is calculated for each series by applying the formula “(good – poor + 100)/2” or, for Traffic, “(high/very high – low/very low + 100)/2”.
Each resulting index is first seasonally adjusted, then weighted to produce the HMI. The weights are .5920 for Present Sales, .1358 for Sales for the Next Six Months, and .2722 for Traffic. The weights were chosen to maximize the correlation with starts through the following six months. The HMI can range between 0 and 100.
