The decision to invest in multifamily is one conversation; the mechanics of actually buying an apartment building are a separate, much more procedural one. Financing structure, underwriting the seller's financials, and lining up management before closing all shape whether a good-looking deal on paper turns into a good-performing asset in year one.
Financing Runs Differently Than a Single-Family Purchase
Buildings with five or more units are financed as commercial real estate rather than through residential mortgage products, which means underwriting centers on the property's net operating income and debt service coverage ratio rather than the buyer's personal income alone. Agency debt through Fannie Mae or Freddie Mac programs offers some of the most competitive terms available for stabilized properties, while bank and bridge financing typically fill the gap for value-add deals that don't yet qualify for agency underwriting.
Reading the Seller's T12 Instead of Trusting It
The trailing twelve-month operating statement a seller provides is a starting point, not a verified fact, and it's common for sellers to present a T12 with deferred maintenance excluded or one-time expenses stripped out to inflate apparent net operating income. Pulling utility bills, tax records, and actual rent roll data independently, and comparing that against the T12 line by line, is the step that catches an inflated income number before it gets baked into a purchase price.
Property tax reassessment after a sale is another line item worth modeling separately, since a jurisdiction that reassesses at the new purchase price can push the tax bill well above what the seller's T12 shows, particularly in markets where assessed value had lagged market value for years under the prior owner.
Unit Mix and Renovation Scope Drive the Business Plan
A building's mix of studio, one-bedroom, and two-bedroom units, along with the condition of unrenovated units relative to already-upgraded comparable units in the same submarket, determines how much upside a value-add strategy actually has. Buyers underwriting a renovation program need real contractor bids on a sample of units rather than a per-door renovation estimate pulled from a different market, since finish costs and permitting timelines vary widely by city.
Lining Up Management Before, Not After, Closing
An apartment building without a management plan in place at closing tends to bleed occupancy in the first few months, since even a short gap in leasing coverage or maintenance response lets small problems compound. Interviewing property management companies, confirming fee structure, and transferring or terminating existing leases and vendor contracts are all closing-table logistics that need to be resolved before the deed transfers, not worked out afterward.
Existing tenant leases also need review before closing, since a new owner generally inherits the lease terms in place, including any concessions or below-market renewals the prior owner signed to fill units quickly ahead of a sale.
Skipping the Operating Work With a DST Interest
Every step above - financing, T12 verification, renovation underwriting, management setup - disappears for an investor who instead buys a fractional interest in a Delaware Statutory Trust holding a multifamily portfolio, since the sponsor has already completed that work before the offering goes to market. The tradeoff is that the DST buyer has no input into financing terms, renovation scope, or manager selection; those decisions were made before the investor's capital arrived, and a 1031 exchanger weighing a direct purchase against a DST allocation is really choosing between control over these mechanics and freedom from managing them.
Common 1031 Exchange Questions
How is an apartment building loan different from a home mortgage?
Commercial multifamily loans are underwritten primarily against the property's net operating income and debt service coverage ratio rather than the borrower's personal income, and they typically carry shorter terms with a balloon payment or refinance requirement rather than a 30-year fixed structure.
What red flags show up in a seller's T12 statement?
Common red flags include one-time expenses excluded from the operating statement, below-market property management fees that won't hold once a new manager takes over, and repair or maintenance line items that look unusually low relative to the building's age and condition.
How many units does a building need to be financed as commercial real estate?
Five or more residential units generally moves a property into commercial multifamily financing, while properties with one to four units are typically financed with residential mortgage products even when purchased as an investment.
Can a DST interest replace an apartment building sold in a 1031 exchange?
Yes, a Delaware Statutory Trust interest is one of the property types that qualifies as like-kind replacement property for a 1031 exchange, provided the offering and the exchange are structured correctly by a qualified intermediary.
What should be reviewed before hiring a property manager for a newly purchased building?
Fee structure, reporting frequency, maintenance response protocols, and references from other owners with similar-sized buildings in the same market are the standard items to confirm before signing a management agreement.
