Real estate investing with high interest rates works when the property's income covers its debt with room to spare, which in late 2026 means underwriting to a debt service coverage ratio first and to appreciation last. With the Federal Reserve's target range at 3.75% to 4% as of its September 16, 2026 decision and the 30-year fixed mortgage average at 7.32% as of October 22, 2026, many deals that closed easily at 3% to 4% money no longer qualify for the same loan size.
This guide covers what has changed for real estate investing with high interest rates, how lenders size loans with DSCR, how to read the spread between cap rates and borrowing costs, and which tax rules (1031 exchanges and permanent 100% bonus depreciation) improve after-tax cash flow while debt stays expensive.
As of September 16, 2026, the date of the most recent Federal Open Market Committee statement, the Committee had raised rates by a quarter point. Its September 16, 2026 statement says the Committee "decided to raise the target range for the federal funds rate by 1/4 percentage point to 3-3/4 to 4 percent," and adds that "Inflation remains elevated." The vote was 12 to 0. The next meeting runs October 27 to 28, 2026, according to the FOMC meeting calendar, so check for a newer statement before you lock any financing assumptions.
Longer-term rates matter more for property loans than the fed funds rate. The Fed's H.15 selected interest rates release showed the 10-year Treasury yield between 4.96% and 5.15% from October 19 to 23, 2026, with the effective federal funds rate at 3.88% on each of those days. Freddie Mac's Primary Mortgage Market Survey reported that "The 30-year fixed-rate mortgage averaged 7.32% as of October 22, 2026," compared with 6.19% a year earlier.
| Benchmark | Reading | As of |
|---|---|---|
| Fed funds target range | 3.75% to 4.00% | Sept 16, 2026 (FOMC statement) |
| Effective fed funds rate | 3.88% | H.15, Oct 19 to 23, 2026 |
| 10-year Treasury yield | 4.96% to 5.15% | H.15, Oct 19 to 23, 2026 |
| 30-year fixed mortgage average | 7.32% | Freddie Mac PMMS, Oct 22, 2026 |
| 15-year fixed mortgage average | 6.68% | Freddie Mac PMMS, Oct 22, 2026 |
| 30-year fixed, one year earlier | 6.19% | Freddie Mac PMMS, Oct 22, 2026 release |
The PMMS figures describe conventional, conforming loans for owner-occupied homes. Investor and DSCR loans usually price above that benchmark (practitioner guidance), so treat the October 22, 2026 average of 7.32% as a floor when you model a rental purchase.
Net operating income (NOI) is rent and other income minus operating expenses, before debt service and income tax. The cap rate is NOI divided by price. Annual debt service is every principal and interest payment for the year. Our guide to real estate investment metrics like cap rate, cash-on-cash and DSCR defines each one in more detail.
Rising rates change debt service while NOI stays put. On a 30-year amortizing loan, each $100,000 borrowed costs about $8,186 a year at 7.25% and about $6,813 at 5.5%. That gap, roughly $1,373 per $100,000, comes straight out of cash flow.
As a result, the lender's coverage test now sets loan size more often than the purchase price does, and a deal can appraise at full value yet leave you writing a larger equity check.
The debt service coverage ratio equals NOI divided by annual debt service. A DSCR of 1.00 means the property earns exactly enough to pay its mortgage and nothing more. Commercial and DSCR lenders commonly set minimums in the 1.20 to 1.30 range for stabilized rental property (practitioner guidance; each lender's term sheet controls, and smaller markets often require more).
DSCR matters for two reasons. It sets the maximum loan amount, since the lender solves for the largest payment that still clears its minimum. It also measures your margin for error, because a property at 1.10 can absorb only about a 9% drop in NOI before cash flow turns negative.
To find the largest loan a property supports, work backward:
A real estate financial model for investors can automate the back-solve across rate and rent scenarios.
All figures here are illustrative round numbers, including the 7.25% rate.
The property: a small multifamily building priced at $1,000,000 with NOI of $68,000, a 6.8% cap rate.
Plan A: 75% loan-to-value at 7.25%, 30-year amortization.
A 1.11 DSCR fails a 1.25 minimum. A 10% drop in NOI to $61,200 would push DSCR just under 1.00 and cash flow to about negative $196 a year.
Plan B: size the loan to a 1.25 DSCR at 7.25%.
Plan C: the same 75% loan at 5.5%. Annual debt service falls to $51,101.01, DSCR rises to 1.33 and cash flow reaches $16,898.99, a 6.76% cash-on-cash return.
| Scenario | Loan | Rate | Annual debt service | DSCR | Cash-on-cash |
|---|---|---|---|---|---|
| A: 75% LTV | $750,000 | 7.25% | $61,395.87 | 1.11 | 2.64% |
| B: sized to 1.25x | $664,540 | 7.25% | $54,400.00 | 1.25 | 4.05% |
| C: 75% LTV | $750,000 | 5.50% | $51,101.01 | 1.33 | 6.76% |
To keep a $750,000 loan at 7.25% and still hit 1.25, NOI would need to reach about $76,745. At the same 6.8% cap rate, that income level corresponds to a property worth roughly $1,128,600, which tells you how far rents or expenses must improve before the original loan size makes sense. For a line-by-line version of this exercise on your own property, see our walkthrough of rental property cash flow analysis.
The spread between a property's cap rate and its cost of debt tells you whether borrowing helps or hurts returns. When the cap rate exceeds the loan constant, each borrowed dollar earns more than it costs and the spread is positive. When the loan constant exceeds the cap rate, adding debt lowers the cash return on equity, and the spread is negative.
In the example, the 6.8% cap rate sits below the 8.186% loan constant at 7.25%, a negative spread of about 1.39 percentage points. That is why Plan A produces a 2.64% cash-on-cash return on a property yielding 6.8% unlevered. Paying all cash would earn 6.8% on equity in year one, more than any levered version at today's rates. At 5.5%, the loan constant of 6.813% is close to the 6.8% cap rate, so borrowing roughly breaks even and Plan C earns 6.76%.
Use the loan constant rather than the interest rate here, since amortization adds principal to each payment. Watch the 10-year Treasury as well: many commercial loans price as a spread over Treasuries, and with the 10-year yield near 5% as of October 23, 2026, fixed-rate investor debt is unlikely to price below that level, which leaves a thin or negative spread on properties bought at cap rates in the 5% to 7% range.
A negative spread can be acceptable when the business plan raises NOI quickly, through renovation or below-market leases rolling over, or when the investor plans to pay down debt from other cash flow.
Price the deal on the rent roll you can verify today, and stress projected rent growth and exit cap rate assumptions separately. Our guide to cash flow scenario planning techniques explains how to build base, downside and severe cases.
Since higher rates compress what a given NOI supports in loan proceeds, raising NOI becomes the main lever you control. Renovating units for higher rent, billing back utilities, appealing property tax assessments and renegotiating service contracts all lift the numerator in DSCR. Each $1,000 of added NOI supports about $9,770 of additional loan at a 1.25 DSCR and a 7.25% rate.
Sellers who own property free and clear may accept payments over time at a rate below bank pricing, especially if they want steady income or would face a large tax bill on a lump-sum sale. Existing loans that permit assumption let a qualified buyer take over the seller's lower rate. Most conventional mortgages contain a due-on-sale clause, so "subject-to" purchases that leave the seller's loan in place without lender consent carry real legal risk and need an attorney's review.
Hold six to twelve months of debt service and capital expenditure reserves (practitioner guidance), especially if a balloon or rate reset falls within the next three years. If you plan to refinance, model the new loan at today's rates and confirm the property still clears the lender's DSCR minimum at that payment. For the broader cash management side, our article on managing business finances in a high interest rate economy covers working capital and credit line strategy.
When loan sizing is tight, clean financials can be the difference between approval and a smaller offer. Lenders want trailing 12-month operating statements, current rent rolls, tax returns and a schedule of real estate owned. Our checklist for business loan preparation and documentation lists what underwriters usually request.
Several tax rules can offset part of the pre-tax squeeze in 2026.
Residential rental buildings depreciate over 27.5 years and nonresidential real property over 39 years under 26 U.S.C. § 168. Land does not depreciate; IRS Publication 527 states, "You can't depreciate the cost of land because land generally doesn't wear out, become obsolete, or get used up." In the illustrative example, if $800,000 of the $1,000,000 price is allocated to the building, a full year of straight-line depreciation is about $29,090.91, which more than covers the $13,600 of Plan B cash flow on paper.
The One Big Beautiful Bill Act (P.L. 119-21) made bonus depreciation permanent. The IRS announcement of Notice 2026-11 says the law "provides a permanent 100-percent additional first year depreciation deduction for qualified property acquired... after Jan. 19, 2025." Bonus depreciation applies only to property with a recovery period of 20 years or less, so the building shell itself does not qualify. A cost segregation study can reclassify components such as appliances, flooring, site improvements and parking areas into 5, 7 and 15-year classes that do. Our explainer on Notice 2026-11 and the transition rules covers elections, and our guide to cost segregation for real estate explains when a study pays for itself.
Large first-year deductions are only useful if you can use the losses. Rental losses are generally passive, so read our summary of passive activity loss rules for rental property before you count on the deduction against wages. Depreciation also comes back on sale, as our article on depreciation recapture in real estate explains.
IRS Publication 527 confirms, "You can deduct mortgage interest you pay on your rental property." Larger investors and entities should also check the business interest limitation under section 163(j). Our update on the business interest expense limitation for 2026 covers the calculation and the real property trade or business election.
High rates make it harder to replace a sold property, and paying tax on the gain shrinks the equity you can redeploy. A like-kind exchange defers that gain. The Form 8824 instructions state that "section 1031 like-kind exchange treatment applies only to exchanges of real property" held for use in a trade or business or for investment. Timing is strict: "The replacement property for the exchange must be identified within 45 days after the property being given up is transferred," and you must receive it by the 180th day after the transfer or the due date of your return including extensions, whichever is earlier.
In a high-rate market, those deadlines create pressure to overpay or accept poor financing on the replacement. Line up financing terms before you list the relinquished property. On Form 8824, net liabilities assumed by the other party count toward the gain you recognize, so replacing less debt than you paid off can create a taxable amount unless you take on new debt or add cash. State rules can add withholding or clawback provisions, covered in our guide to state-specific 1031 exchange rules.
Is real estate investing with high interest rates still worth it in 2026? It can be, if the property covers its debt at today's rates with a DSCR of roughly 1.25 or better and you are not relying on appreciation or a lower-rate refinance to make the numbers work.
What DSCR do lenders require for rental property? Minimums commonly fall between 1.20 and 1.30 for stabilized rentals, with higher requirements in smaller markets or for weaker property types. This is practitioner guidance; the term sheet controls.
What happens when the cap rate is lower than the mortgage rate? The debt spread is negative. Borrowing lowers your cash-on-cash return below the property's unlevered yield, as the worked example shows with a 6.8% cap rate producing a 2.64% cash return at 75% loan-to-value.
Does 100% bonus depreciation apply to a rental building? The building itself does not qualify because its recovery period is 27.5 or 39 years. Components with a recovery period of 20 years or less, often identified through a cost segregation study, can qualify for the permanent 100% deduction if acquired after January 19, 2025.
How do high interest rates affect a 1031 exchange? The 45-day and 180-day deadlines do not change, though financing a replacement property takes longer and costs more. Replacing less debt than you paid off can create taxable gain, so plan the replacement loan before the sale closes.
