Resale Formula Comparison
For Shared Equity Homeownership Programs
Overview: All shared equity homeownership programs attempt to balance two competing goals: providing homeowners with an opportunity for meaningful wealth creation and preserving the value of public subsidies so that they can serve additional families into the future. Different shared equity models balance these goals in different ways, however. This spreadsheet provides a side-by-side comparison of three different shared equity programs, allowing users to evaluate each program's likely performance in meeting both of these goals under a wide range of potential economic circumstances.
Initial Subsidy Based on the information provided by the user, this spreadsheet assumes that at the time of the initial subsidy, a 3 bedroom house in the user's market would sell for $300,000. At this price the home would be affordable to a family earning 119% of the Area Median Income. (A house is considered affordable when the homeowner spends no more than 35% of their income on housing costs.) In order to make this home affordable to families earning 80% of the Area Median Income (the target income level that the user has specified), the program sponsor will need to provide $120,000 in subsidy. In some shared equity programs this subsidy would be provided as a second loan to the homeowner, while in other programs the subsidy would be used to reduce the initial cost of the unit to an affordable level so that no second loan is necessary.
Shared Equity Models Using the inputs specified by the user, this spreadsheet compares three different program models and a market rate transaction. The program models are: Shared Appreciation Loan This approach involves making a second mortgage directly to the homebuyer with no payments due until the home is sold. Upon sale the homeowner repays the full amount of the initial loan plus a share of any appreciation in the value of the home. Under the particular shared appreciation loan formula examined here, the share of appreciation owed to the program sponsor is based on the percentage of the initial purchase price that comes from the second loan. For example, if the program provides a second mortgage equal to 20 percent of the cost of a home, the family must pay the program 20 percent of the home price appreciation upon selling the home. Area Median Income Resale Price Restriction Rather than using subsidies to make a second loan, this approach lowers the initial price to an affordable level and then ties the sale price to changes in the Area Median Income. When the homeowner sells, he or she receives the amount initially paid for the home plus that initial price times the change in the Area Median Income. Affordable Housing Cost Resale Price Restriction This approach requires homeowners to sell at whatever price is "affordable" to buyers in the future earning the target income level (in this case, 80% of median income) given whatever the interest rates and other likely costs are in the future. This model works backwards from the costs to identify the affordable price.

Reading the Results
This spreadsheet compares these three shared equity approaches (and a market rate transaction) in terms of how much equity the homeowners receive and how well each approach maintains affordability. The approaches are compared under several alternative economic scenarios. The COMPARISON worksheet provides a high-level overview of what happens after the initially assisted family decides to sell its home. For each model, the worksheet shows: (a) the loss or gain of affordability as expressed in the income level to which the home will be affordable upon resale; (b) the amount of additional subsidy, if any, that will be required to make the home affordable to the next buyer at the original target income level; (c) how much equity the family has gained at the time of sale; and (d) the annual rate of return on the family’s initial cash investment; The COMPARISON worksheet provides results for each model using the base economic scenario while the SCENARIOS worksheet provides results under a range of different assumptions about the economic future. The SHARED APPRECIATION, AMI, and AHC worksheets provide the details behind the calculations for each of the shared equity approaches examined here. Economic Scenarios The relative performance of these different shared equity approaches depends on several key assumptions about future economic conditions, especially the rate of home price inflation, the rate of increase in the median income and the change in mortgage interest rates. The spreadsheet shows detailed results for each approach under a basic set of economic assumptions (the base scenario) but also shows summary results for up to 5 Alternative Scenarios input by the user. Approaches that perform well under one economic scenario may not perform as well under other circumstances; the SCENARIOS worksheet allows us to evaluate these approaches under a wide range of conditions.
Key Terms
Holding Period is the time before the first buyer sells the home. Median Home Price Inflation is the expected annual change in the median home price over the time that the first homeowner owns the home. Median Income Inflation is the projected average annual change in the Area Median Income over the same period of time. Initial Mortgage Interest Rate is the interest rate for 30 year fixed loans at the time of the initial purchase. Interest Rate at Resale is the projected rate that the second buyer will pay on a similar mortgage. By varying these assumptions we get a more complete picture of the relative performance of the different shared equity models. Affordability Resale Price: For each model the spreadsheet shows the price at which the home will sell after the holding period. For the market and shared appreciation models, this is the initial price times the change in home prices. For the AMI and AHC formulas this is the price calculated by the appropriate resale formula (see above for an explanation). Affordability at Resale: Given these prices, the spreadsheet calculates the "Affordability at Resale" which is the percentage of the Area Median Income a new buyer would need to earn in order to purchase the unit and pay the appropriate percentage of his or her income for housing costs. Second Loan at Resale: Under the Shared Appreciation model there is also a Second Loan at Resale, which is the total amount which the seller must repay to the program upon resale. This is equal to the initial subsidy plus the share of appreciation. The Affordability at Resale for this model assumes that this money is re-lent to the second buyer to reduce the second buyer's costs. (As you will observe, this may or may not be enough to maintain the initial level of affordability.)

Additional Subsidy Needed: When there is a loss of affordability, the program sponsor might need to invest additional subsidy to make the home affordable to a subsequent buyer at the target income level. The spreadsheet calculates the amount of subsidy that would be necessary to maintain affordability to the target income group. When this number is negative, the sponsor could withdraw funds at resale without reducing affordability. Asset Building Initial Investment: A homeowner's initial investment is the sum of his or her downpayment and closing costs. To facilitate comparison, Shared Appreciation owners are assumed to provide the same downpayment as the AMI and AHC owners. (Based on the user-specified inputs, the comparision currently assumes the downpayment to be 3% of purchase price and closing costs 2%.) Homeowner's Net Return: At sale, the net return to the homeowner is calculated as the resale price minus the principal owed on any mortgages, minus broker and other sales costs. (Based on the user-specified inputs, the comparision currently assumes sales costs to be 7% of the sales price for below market units.) Approximate Rate of Return: This is the annual rate at which the homeowner would have had to invest the money he or she contributed toward downpayment and closing costs to make as much money as he or she earns on the sale of the home.
