For apartment acquisitions

Multifamily underwriting software

  • I underwrite apartments as a per-unit business.
  • Count the units, take the average rent, take out vacancy, pay the expenses, and what is left is NOI.
  • The loan is the next question.
  • Does that NOI cover the payment.

What the software does

  • Underwrite runs that pass in one model.
  • You enter the units, the rent, the vacancy, the operating costs, and the loan.
  • The engine returns year 1 NOI, the going-in cap rate, project IRR, the equity multiple, minimum DSCR, and a verdict of PURSUE or PASS.
  • The return is computed by tested code.
  • A language model can read an offering memorandum into the inputs.
  • It does not compute the return.
  • You can open any assumption and watch the plate move.

What a multifamily model has to hold

  • The useful first pass is short.
  • Gross potential rent is units times monthly rent times 12.
  • Vacancy comes off.
  • Other income goes on.
  • Operating expenses come off.
  • That is NOI.
  • Debt service is not an operating expense, so it is not inside NOI.

One average rent is a simplification. A real community has studios and larger homes, and the mix can shift. This model keeps a single average, on purpose, so the first pass stays checkable. The limit is written on the multifamily methodology page.

Worked example

  • Lakeshore Garden Apartments in Cleveland, OH is the gallery's multifamily case.
  • It is 48 units at $2,200.00 a month, vacancy 5.00%, other income $60,000.00 in year 1, priced at $16,000,000.
  • There is no retail income.
  • The loan is 65% of price at 6.25%, and the hold is 7 years.

Every figure below is that case run through the engine. Vacancy and operating expenses print in parentheses, which is the engine's sign for a reduction.

  • The verdict is PASS.
  • Project IRR is 12.14%.
  • Minimum DSCR is 1.21x.
  • PURSUE needs the IRR at or above the hurdle and minimum DSCR at or above 1.00x.
  • This case does not clear both.
