Multifamily owners already have a long list of expenses that have gotten harder to manage—insurance, utilities, taxes. Now there's another cost creeping up that hasn't gotten as much attention, but probably should.
According to Trepp, the actual cost of maintaining and repairing apartment properties has risen significantly in recent years. The problem is that reserve requirements—the funds set aside for those inevitable repairs—haven't kept pace.
For years, lenders have operated with fairly standard assumptions. Trepp found that Fannie Mae and Freddie Mac have typically required about $250 per unit annually in reserves, with very little change over time. CMBS conduit loans have shown a bit more range, generally between $243 and $327 per unit, but not enough to reflect the kind of cost increases owners are now seeing.
In fact, Trepp pointed to a recent conduit deal in which every multifamily loan carried the same $ 250-per-unit reserve requirement, regardless of whether the property was newly built or decades old. That kind of uniformity is where the disconnect starts to become obvious. Older buildings simply need more work—more replacements, more upgrades—and the numbers don't reflect that.
Trepp put some specifics around the issue. In a hypothetical example, replacing flooring or carpeting in a 1,000-square-foot unit in New York City now runs about $11,000. That's an increase of more than 70% since 2010.
Looking at broader data tells a similar story, even if the numbers aren't quite as steep. GlobeSt.com analyzed Bureau of Labor Statistics Producer Price Index data for final demand construction, which includes both new construction and ongoing maintenance and repair. From May 2013 through May 2026, those costs rose 58.3%. The gap between that figure and Trepp's estimate likely comes down to geography—New York versus national data—and the longer time frame Trepp used.
Either way, the direction is clear. Costs are rising, and reserve assumptions have barely moved.
Trepp suggests lenders may need to rethink those assumptions. Big-ticket items alone can blow through current reserve levels. "A roof, for instance, might need to be replaced every 20 years or so, depending on the property's location and condition," Trepp noted. "That alone could run well north of $15,000."
For owners, the tradeoff is straightforward but painful. Higher reserves mean lower net operating income, at a time when margins are already under pressure. For lenders, sticking with outdated assumptions risks understating how much capital these properties will actually need over time.
Whether the industry will adjust remains an open question. But the gap between what things cost and what's being set aside to pay for them is getting harder to ignore.
