Buying an apartment building is a different process than buying a house, starting with how the purchase is priced. Instead of comparable single-family sales, the seller's broker builds an offering memorandum around the building's net operating income, and the buyer's job is to test whether that income figure holds up once actual expenses, not the seller's optimistic projections, are plugged in. Around Indianapolis, that testing matters more than usual right now given how much insurance and tax expenses have moved over the past few years.
Reading the Rent Roll Before Anything Else
The rent roll shows current rent for every unit, lease start and end dates, and any concessions or delinquencies, and it is the single document that most reliably separates an accurately marketed building from an inflated one. A rent roll showing several units at below-market rent because of long-tenured residents can represent real upside once those units turn over, but it can also mean an owner has been avoiding vacancy risk by underpricing rather than actively managing the asset, and only a closer look at turnover history tells the difference.
Underwriting the Trailing Twelve Months, Not the Pro Forma
Sellers market apartment buildings using pro forma numbers that assume immediate rent increases to market rate and expense ratios that don't always reflect what the building has actually cost to run. A buyer who underwrites off the trailing twelve months of actual income and expenses gets a much more honest picture, even if it produces a less exciting number than the marketing deck. This matters especially for buildings in Indianapolis neighborhoods that have seen recent reassessments, where the property tax line in a pro forma can lag behind the actual current bill by a wide margin.
Financing and the Debt Service Coverage Test
Commercial lenders underwrite apartment loans against the property's net operating income relative to the proposed debt payments, typically requiring the building to clear a debt service coverage ratio around 1.20 to 1.25. A building that looks attractive on price per unit can still fail to qualify for the loan amount a buyer wants if the actual, verified income doesn't support that debt load, which is why the financing conversation with a lender should start early rather than after a purchase agreement is signed.
Closing an Apartment Purchase Inside a 1031 Timeline
Apartment buildings are common exchange replacement property, but they also carry more closing friction than a single-tenant net lease deal, since lender underwriting, property condition assessments, and sometimes tenant estoppel certificates all take time that can strain a 180-day exchange window. Exchangers targeting a specific Indianapolis building should get financing pre-approved and inspections scheduled as early in the process as possible, since a lender delay late in the window can jeopardize the closing date the exchange depends on. Naming a backup candidate on the identification list, even a less preferred one, gives the exchange room to close on time if the primary building's financing or estoppel process runs long.
