When federal debt crossed $40 trillion in August, the average apartment cap rate was 5.39% against a 4.71% 10-year Treasury yield, according to RealPage. That is a cushion of only about 0.7 percentage points, the thinnest of the four $10 trillion milestones RealPage compared going back to 2008. For owners with a loan coming due, that thin cushion is the number to plan around this quarter.
What happened
RealPage deputy chief economist Arben Skivjani lined up apartment conditions at each $10 trillion step in federal debt. In September 2017, the cap rate was 5.68% with the 10-year near 2%, a spread of roughly 3.6 points. In August 2026 the same spread had shrunk to about 0.7 points.
Rates have kept moving since August. The Federal Reserve raised its target range by a quarter point to 3-3/4 to 4 percent on Sept. 16 by a 12–0 vote, saying inflation "remains elevated." RealPage reports the 10-year yield reached 5.29% by Sept. 30, and notes that cap rates usually take a few quarters to catch up.
Capital is moving more slowly too. RealPage puts apartment deal volume at about $194 billion a year, a little more than half the $347 billion pace seen when debt crossed $30 trillion in early 2022.
Meanwhile, the maturity calendar does not wait. The Mortgage Bankers Association's loan maturity survey found that 13% of mortgages backed by multifamily properties are scheduled to mature in 2026. Only $39 billion, or 4%, of the multifamily and health care balances held or guaranteed by Fannie Mae, Freddie Mac, FHA and Ginnie Mae matures this year. RealPage reads that split as meaning most 2026 multifamily maturities sit with banks, life insurers, debt funds and CMBS, and notes that many loans taken out near the $30 trillion milestone in early 2022 were made when the 10-year was below 2%.
Why it matters for property managers
Value is set by the spread, and the spread is tight. When cap rates sit barely above what a Treasury pays, buyers and lenders have little reason to accept a lower yield on an apartment. If the 10-year stays near where it ended September, the RealPage analysis implies cap rates face upward pressure over the next few quarters. Higher cap rates on the same NOI mean lower values, and lower values mean smaller refinance proceeds.
Your NOI is the lever that is still in your hands. Owners cannot move the 10-year. They can protect the income line that a lender underwrites. On that front the operating picture is steadier than the capital picture. RealPage's third-quarter update shows national occupancy at 95.4%, with same-store effective asking rents up 0.9% year over year, the first positive annual rent growth since the second quarter of 2025.
Concessions still cost real money. RealPage found about 22.7% of apartments offered concessions, averaging 7.5%. A lender looking at trailing collections, not asking rents, will see every free month.
Supply relief is coming, but slowly. Completions over the year ending in the third quarter were nearly 318,000 units against about 304,800 absorbed, a gap of 13,000 units that RealPage calls the narrowest since late 2015. Units under construction have fallen from a peak of 1.1 million in early 2023 to about 550,000, so deliveries should thin over the next couple of years. That should help pricing power later, but it does not fix a loan maturing this year.
Who holds the loan changes the conversation. MBA's survey shows 21% of depository-serviced balances and 25% of CMBS, CLO and other ABS balances across all commercial property types come due in 2026. Bank and CMBS loans often have very different extension and modification paths, so the same NOI can lead to different outcomes depending on the lender. Read your own loan documents and confirm the specifics with your lender and counsel.
What to do this week
- List every loan maturing through 2027. For each, note the lender type, maturity date, extension options and any debt service coverage or debt yield tests that apply to an extension.
- Re-run refinance math at today's rates. Underwrite proceeds with a cap rate that is higher than your last appraisal and a 10-year near recent levels. If the result is a cash-in refinance, you want to know now, not weeks before maturity.
- Clean up the trailing-12 the lender will see. Reconcile concessions, bad debt and other income. Burn off one-time concessions where the submarket allows, and document why any remaining ones are temporary.
- Put retention ahead of rate on renewals. With occupancy at 95.4% nationally, a vacant unit often costs more in turn and downtime than a small renewal discount. Price renewals unit by unit against your own comps.
- Talk to your lender early. Ask what an extension or modification would require. Lender appetite and terms vary, so treat this as information gathering, not a commitment, and bring in counsel before signing anything.
- Tighten controllable expenses. Review service contracts, utility recovery and payroll scheduling. Every dollar of expense saved is a dollar of NOI at the same cap rate.
What we're watching
- The Fed's Oct. 27–28 meeting. The FOMC is scheduled to meet Oct. 27–28. Any decision there is not yet known; watch the statement for whether officials still describe inflation as elevated.
- The 10-year yield. RealPage names it as the number that drives apartment loan costs and, over time, building values. A move back down would widen the cap-rate cushion; a further climb would squeeze it.
- Fourth-quarter concessions. If the share offering concessions stays near the 22.7% RealPage measured through the slow leasing season, effective rent growth may stay close to flat.
- Extensions versus payoffs. MBA's survey shows $652 billion of commercial and multifamily mortgages scheduled to mature in 2027. How lenders treat 2026 maturities will shape how much of that wall rolls forward.
