When the loan comes due

If you borrowed against your building between 2019 and 2022, you got a deal that no longer exists. Coupons in that window commonly ran 3.25% to 4.25%. Today a small apartment loan prices closer to 6.25% to 6.85%.

That gap is the whole story, and how badly it lands on you depends almost entirely on one thing most owners never think about.

Where rates actually are

As of mid-September 2026, the Federal funds target sits at 3.50% to 3.75%. The ten-year Treasury is near 5.00% — the highest since 2007 — driven up by oil above $100 a barrel and an August CPI reading of 3.4%. Markets are pricing a rate increase at the September meeting, which would be the first since 2023.

Indicative quoted rates for small multifamily permanent debt, mid-September 2026:

Those are advertised best-case quotes from broker rate boards, not closed-transaction data. Real pricing moves with leverage, sponsor, and property. Loans under about $6 million consistently price 40 to 50 basis points wider than larger ones — a small-loan penalty that is real and measurable.

The number that decides everything: interest-only or not

Two owners each borrowed $2,000,000 in 2021 at 3.75% on a five-year term. Same building type, same rents. One took a loan that amortized over thirty years. The other took full-term interest-only, because the payment was lower and the broker said everyone was doing it.

Both loans mature now. Assume the building produces $165,000 of net operating income, and assume today's lender wants 6.35% with a 1.25x debt service coverage ratio — meaning the building's income has to exceed the new mortgage payment by 25%.

At those terms, $165,000 of NOI supports a loan of about $1,768,000.

• The amortizing borrower has been paying principal for five years. The balance is down to roughly $1,802,000. They are short about $34,000 — an irritation, not a crisis. They write a small check or negotiate, and move on.
• The interest-only borrower still owes the full $2,000,000. They are short $232,000, nearly seven times as much, and have to fund it before the lender will close.

If that building's NOI is $150,000 instead, the interest-only gap widens to $393,000. At $140,000, it is $500,000. The amortizing borrower's gap grows too, but from a much lower base — it is the five years of principal paydown that does the work, and interest-only buys none of it.

Writing a check to refinance a property you already own is called a cash-in refinance. Nobody publishes how common it has become, because no one tracks it in commercial real estate. But the direction is clear: Arbor's data put the average achieved loan-to-value on small multifamily at 63.4% in the second quarter of 2026, against advertised maximums of 75% to 80%. Lenders are advertising eighty and delivering sixty-three.

A rule of thumb worth memorizing

At 1.25x coverage, 6.35%, and thirty-year amortization, every $1 of annual net operating income supports roughly $10.70 of loan.

Turn that around and it becomes the most useful sentence in this article: every $1,000 of new annual operating expense destroys about $10,700 of borrowing capacity.

A twelve-unit building whose insurance goes from $500 to $1,800 per unit per year loses $15,600 of NOI — and about $167,000 of loan proceeds. That is why we spend so much time on the expense side of a rent roll. It is not bookkeeping. It is the loan.

The maturity wall is smaller than the headlines, and aimed somewhere specific

You have probably read that a wall of commercial debt is coming due. It is true, and it is mostly not aimed at you.

The Mortgage Bankers Association found that $875 billion — 17% of all outstanding commercial mortgages — matures during 2026. But multifamily is the least exposed category, at 13% of balances. And the exposure is wildly uneven by who holds the loan:

• Government-backed (Fannie, Freddie, FHA): 4% of their balances mature in 2026
• Banks and credit unions: 21%
• CMBS and CLO: 25%
• Debt funds and credit companies: 29%

The delinquency numbers tell the same story. Multifamily CMBS delinquency hit 7.69% in July 2026, the highest in years. Freddie Mac's book sits at 0.47%. Fannie's at 0.56%. Banks at 1.47%.

So the "multifamily debt crisis" is largely a CMBS, bridge-lender, and syndicator story. If you have an agency loan on a stabilized building, you are in the calm part of the ocean. If you have a bank loan, a debt-fund loan, or a bridge loan you meant to refinance two years ago, you are in the exposed cohort.

One more wrinkle worth checking your own documents for: about 22% of Freddie's maturing loans carried a supplemental second lien averaging roughly a quarter of the first. If you took a supplemental in 2021 to pull cash out, both pieces come due together.

The prepayment window almost nobody mentions

This one is counterintuitive and, right now, genuinely valuable.

If your loan carries a yield maintenance prepayment penalty, the penalty exists to make the lender whole for interest they lose when you pay early. It is calculated against current Treasury rates. When rates rise above your loan's coupon, the lender loses nothing by being paid off — they can reinvest at a higher rate.

So yield maintenance penalties shrink as rates rise, and most contracts floor them at about 1%.

If you signed a 3.75% loan in 2021 with yield maintenance, and the comparable Treasury is now at 5.00%, your penalty is very likely at or near that 1% floor. Breaking that loan may cost a fraction of what you assume. This is the cheapest it has been in five years to get out of a low-rate loan, which is a strange sentence to write and a real opportunity for some owners.

The other structures behave differently:

• Step-down (typically 5-4-3-2-1 over five years) is a fixed schedule that ignores rates. Year four on a $2,000,000 loan is $40,000, full stop. Banks and credit unions usually offer this.
• Defeasance substitutes a portfolio of government securities for your collateral. It requires a consultant, runs 30 to 45 days, and the cost is not knowable until you engage one. Standard on securitized loans.
• Lockout is the one that actually stops people. It means the loan cannot be prepaid at any price. Freddie's current small loan product carries a two-year lockout after securitization. Check for this before you plan anything.

Two things that changed in 2026

Freddie Mac's Small Balance Loan program no longer exists as a separate product. On April 15, 2026, Freddie folded it into their core platform as "Conventional Small." Loan size now runs $2 million to $10 million, minimum 1.25x coverage, up to 75% or 80% leverage depending on structure. Most broker websites still say "Freddie SBL." They are out of date. Note the $2 million floor — it cuts off smaller deals, which now go to Fannie's Small Mortgage Loan program (up to $9 million, 80% LTV) or to a bank.

Banks came back. After three years of the agencies dominating, CBRE reports bank multifamily lending up about 30% year over year, with FDIC-insured bank multifamily balances reaching $665 billion in the first quarter of 2026. For a 4-to-20-unit owner, a local bank or credit union quote is now genuinely competitive with agency pricing — often with lower fees, no third-party report costs, and a faster close. The trade is recourse, a shorter term, and less leverage.

What we do with this

We start by reading your actual loan documents, because the four facts that determine your options are all in there and almost nobody remembers them: the maturity date, whether it amortizes, the prepayment structure, and whether there is a lockout.

Then we run the refinance at today's terms and tell you the number. Sometimes the answer is that you refinance comfortably and this was all worry for nothing. Sometimes it is that you need to bring money, and the real question becomes whether to bring it, sell, or restructure. Either way, the time to find out is well before the maturity date, not ninety days ahead of it.
