Who Pays for Development?
The capital stack behind a new apartment building: who lends, who invests, who signs personally, and who ultimately repays all of it.
A 100-unit apartment building can cost tens of millions of dollars, and almost none of that money comes from the developer’s own bank account. It comes from a layered set of lenders and investors, each of whom accepts a different level of risk in exchange for a different level of return. Together those layers are called the capital stack.
By the end of this lesson you will understand what each layer is, in what order the layers get paid, why a lender will fund only part of the cost, who signs personally for the loan, and who ultimately pays for all of it. The short version: the capital comes from lenders and investors, but the money that repays them comes from renters, and sometimes partly from the public.
The layers of the capital stack
Picture the cost of a building as a column. At the bottom sits the senior debt, the largest and safest layer. Above it may sit mezzanine debt, a smaller loan that is riskier than the senior loan and charges more. At the top sits equity, the ownership money that is paid last and loses first. Cash flows to the bottom of the column first when the building does well, and losses hit the top of the column first when it does poorly.
Senior debt
During construction, the senior lender provides a construction loan: a short-term loan, usually from a bank, that is drawn down in stages as work is completed and inspected. Interest accrues on whatever has been drawn. Once the building is leased and stabilized, that loan is typically repaid with a permanent loan, a long-term mortgage sized against the building’s actual income.
The senior lender is secured by a mortgage on the property. If the project fails, the senior lender is repaid first from whatever the property is worth. That priority is why senior debt carries the lowest interest rate in the stack.
Mezzanine debt
Mezzanine debt sits between the senior loan and the equity. It is usually secured not by the property itself but by the ownership interests in the entity that owns the property, and it is repaid only after the senior lender. Because it is repaid second, it charges a higher rate. Developers use it to reduce the amount of equity they need to raise, at the price of more expensive money and less cushion. Our illustration below omits it to keep the arithmetic clear.
Equity
Equity is the money that owns the project. It usually comes from two places: the developer’s own co-investment, and outside investors such as individuals, family offices, funds, or institutions. Equity receives whatever is left after the lenders are paid, which is why it can earn the most and also why it can lose everything.
Outside investors often negotiate a preferred return: a threshold rate of return they receive before the developer shares in profits beyond it. This ties the developer’s reward to the investors’ outcome. If the building underperforms, the developer’s share of the upside disappears first.
Who bears which risk
The order of payment is the order of risk, in reverse. If costs run over or rents come in below plan, equity absorbs the loss first, then mezzanine debt, then senior debt. The senior lender loses money only if the shortfall is larger than the entire mezzanine and equity layers combined.
There is one more party at risk: the developer personally. Construction lenders commonly require a guaranty, a personal or corporate promise to complete the building and to cover shortfalls if the project cannot repay the loan. A completion guaranty means that if the project runs out of money halfway through, the developer is obligated to finish it. That obligation can outlast the developer’s equity.
Why lenders lend only a fraction
A lender’s willingness to fund a project is expressed as a ratio. Loan-to-cost is the loan divided by the total cost of the project. Loan-to-value is the loan divided by what the finished building is appraised to be worth. Lenders cap both, and they also test whether projected income covers the loan payments with room to spare, a measure covered in Lesson 3.
The reason for the cap is simple. If the lender funded 100% of the cost, any cost overrun or rent shortfall would immediately be the lender’s loss. Requiring the owner to put a substantial share of its own money in first means the owner has something to lose, and the lender has a cushion before its own capital is touched.
The illustrative building
We use one illustrative building throughout Housing 101: 100 apartments in a mid-sized city, costing $24,000,000 in total, or $240,000 per unit. All figures are assumed and listed at the end of this lesson. Under our default assumption of 65% loan-to-cost, the stack looks like this.
| Layer | Amount | Share of cost | Position | Who provides it |
|---|---|---|---|---|
| Senior construction loan (later replaced by a permanent loan) | $15,600,000 | 65% | Repaid first; secured by a mortgage on the property | Bank or other senior lender |
| Mezzanine debt | $0 (omitted here) | 0% | Repaid second; secured by ownership interests | Debt fund or specialty lender |
| Equity (developer co-investment plus outside investors) | $8,400,000 | 35% | Repaid last; owns the building | Developer and investors |
| Total development cost | $24,000,000 | 100% |
35% of a $24,000,000 total development cost. This is the layer that absorbs the first dollar of cost overrun or rent shortfall, and it must be spent before the lender advances a dollar. Assumed, not observed.
What the capital costs each year
Capital is not free. The lender charges interest and requires the loan to be paid down over time, and equity investors require a return on the money they have tied up. In our illustration, the $15,600,000 loan at an assumed 6.5% interest rate with 30-year amortization costs $1,183,231 per year in debt service. The $8,400,000 of equity, at an assumed 8% annual cash-on-cash target, requires $672,000 per year. Together that is $1,855,231 per year that the building must produce, after operating expenses, before anyone has earned a profit.
Debt service = monthly payment on $15,600,000 at 6.5%, 30 years × 12 = $1,183,231
Equity return = $8,400,000 × 8% = $672,000
Required net operating income = $1,183,231 + $672,000 = $1,855,231Lesson 3 shows how this figure becomes a required rent.
So who actually pays?
Lenders and investors put the money in, but they expect it back with a return. The only ordinary source of that return is rent. Interest, principal, and investor return are all collected from tenants, month by month, over the life of the building. When people ask who pays for development, the honest answer is that the capital stack fronts the money and the renters repay it.
The exception is public money. Governments sometimes lower the amount renters must cover through incentives: a tax increment financing district that redirects future property tax growth to pay for infrastructure or project costs, a Low-Income Housing Tax Credit allocation that brings in investor equity in exchange for restricting rents, a payment in lieu of taxes agreement, or a fee waiver. Each reduces what the building must earn from rent, and each shifts part of the cost to taxpayers or to forgone public revenue.
Whether that trade is worthwhile is a policy question and depends on what the public gets in return. That it is a trade is arithmetic: a dollar the building does not have to earn from rent is a dollar someone else has supplied. Lesson 7 covers the public side in more depth.
Total development cost $24,000,000 for 100 units ($240,000 per unit): land $2,400,000, hard costs $16,800,000, soft costs $3,600,000, financing costs and contingency $1,200,000. All illustrative.
Loan-to-cost 65% ($15,600,000); equity 35% ($8,400,000). No mezzanine layer in the base illustration.
Interest rate 6.5%, 30-year amortization, giving annual debt service of $1,183,231 (a mortgage constant of 7.585% of the loan per year).
Equity cash-on-cash target 8%, giving $672,000 per year.
The amounts above are a worked example built on the default assumptions described on our Methodology page, not statistics about any market or project. Anyone applying the structure to a real deal should take its costs and terms from local sources.
If lenders accepted a higher loan-to-cost, less equity would be needed, but the loan and its debt service would be larger, and the cushion protecting the lender would shrink, which is why the rate would likely rise.
If mezzanine debt replaced part of the equity, the developer would raise less equity but pay a higher rate on that slice; whether the total annual cost of capital falls depends on whether the mezzanine rate is below the equity target.
If a public subsidy paid part of the cost, the capital stack the renters must repay would be smaller, and the difference would be borne by the public.
Next lesson. Knowing who provides the money explains why a project must earn a certain amount. Lesson 3: How Developers Determine Whether a Project Works walks through the spreadsheet that answers whether it can.
