What an active adult underwriting model needs that conventional multifamily templates do not have
An underwriter moving from conventional apartments into a first 55-plus deal often finds that half of a standard multifamily template does not apply, which makes it worth laying out the differences plainly. Take a 120-unit asset built in 2008, age restricted, one and two bedrooms, with in-place average rent of $1,780 against a comparable conventional product of the same size and vintage two miles away renting at $1,450. Operating expenses running $7,400 a unit against an expected $5,900 on conventional. Turnover last year at 22 percent against an expected 48 percent on conventional. That shape, a rent premium around 23 percent, an expense load around 25 percent higher, and roughly half the turnover, raises three questions worth answering before underwriting to the ask. First, whether the premium is a genuine product premium tied to a real waiting list and age restriction, or a location premium that a conventional operator could erode simply by adding a clubhouse and a walking loop and calling itself active adult. The first case holds over time, the second does not. Second, where the extra expense load actually goes. Some of it is amenity payroll and some is a higher standard of grounds and common area upkeep, and the split matters because cutting the wrong piece can erode the very premium that justifies the higher rent. Third, what lower turnover implies for rent growth. Less make-ready and less vacancy loss are straightforward to model, but fewer turns also mean fewer chances to mark rents to market, so understanding whether rent growth in this asset class comes mostly through renewals rather than turns changes how aggressively to underwrite it. The practical decision usually comes down to whether the premium is durable enough to underwrite at the ask, or whether a more conservative exit cap, perhaps 25 basis points above a conventional exit assumption, better reflects the risk that the premium compresses over the hold.
