How Interest Rate Changes Impact Multifamily Investments
Interest rates are one of the most influential factors in real estate—and multifamily investments are no exception. Whether you're an active operator or a passive investor, changes in interest rates can ripple through every part of a deal: from acquisition and financing to cash flow and exit strategy.
Here’s a breakdown of how interest rate changes impact multifamily investments—and how savvy investors can navigate shifting environments.
1. Loan Costs & Deal Underwriting
The most immediate impact of interest rate changes is on borrowing costs. Higher interest rates increase the cost of capital, which affects:
Monthly mortgage payments
Debt service coverage ratios (DSCR)
Total returns to investors
What this means:
When rates go up, deals become harder to pencil. Margins shrink, and some acquisitions that looked attractive a few months ago no longer meet return expectations.
📉 Rising rates = more conservative underwriting
📈 Falling rates = more aggressive growth projections
2. Cash Flow & Returns
Multifamily properties typically rely on leverage (i.e., debt financing) to amplify returns. But when interest rates rise:
Debt becomes more expensive
Monthly payments go up
Net Operating Income (NOI) may stay the same, but cash flow to investors drops
On the flip side, when rates fall, refinancing becomes a powerful tool to improve cash flow and boost investor returns.
3. Property Values & Cap Rates
Interest rates are closely tied to capitalization rates (cap rates). When interest rates rise, cap rates often follow—leading to a decrease in property values (even if income stays the same).
Why? Because investors require a higher return to offset the higher cost of borrowing.
Example:
A property generating $500,000 in NOI may be worth $10M at a 5% cap rate
But at a 6% cap rate, that same property is now worth just $8.33M
That’s a significant valuation swing based on market sentiment and financing conditions alone.
4. Refinancing & Exit Strategies
In a rising-rate environment, refinancing becomes more challenging—and more expensive. If your business plan includes a refinance in 2–3 years, you’ll need to factor in the possibility that future rates may be higher, not lower.
This also affects exit cap rate assumptions, which are crucial to determining projected sales prices and overall returns.
✅ Smart investors plan for rate volatility by stress-testing their models with different scenarios.
5. Operator Strategies in a High-Rate Market
Strong operators don’t stop investing during high-interest rate periods—they adapt. Here's how:
Buy at a discount: Rising rates often create buying opportunities as competition thins out
Focus on operational efficiency: Improving NOI through better property management can offset higher debt costs
Use interest rate caps or fixed-rate debt: To protect cash flow and limit exposure to rate spikes
Partner with lenders strategically: Build relationships with debt partners who understand multifamily and can offer flexible terms
What Should Passive Investors Watch For?
If you’re investing passively in multifamily deals, ask these questions:
What kind of debt is being used? (Fixed or floating?)
Is there a rate cap in place?
How conservative are the exit cap rate and refinance assumptions?
Is the deal stress-tested against rate hikes?
Being proactive helps you avoid surprises and ensures your capital is protected—even when the market shifts.
The Bottom Line
Interest rates will continue to rise and fall—but the fundamentals of multifamily investing remain strong. Demand for housing, especially affordable rental units, remains high. The key is working with experienced operators who can navigate changing market conditions and structure deals that prioritize both performance and protection.
