How Interest Rates Impact Real Estate Investments

The Basic Relationship

Interest rates affect real estate investment in multiple directions simultaneously. Higher rates increase the cost of borrowing, which reduces the loan amount a given income can support. That reduces buying power and puts downward pressure on property prices. At the same time, higher rates mean higher required returns from investors, which compresses cap rates and challenges values for income-producing properties. The combination creates environments where the deals that made sense at 4% financing may not work at 7%.

Cap Rate Compression and Expansion

Cap rates and interest rates tend to move in the same direction over time, though with a lag. When 10-year Treasury rates are near 1%, investors accept cap rates of 4% to 5% on commercial real estate because the spread over risk-free rates is acceptable. When Treasury rates move to 4% to 5%, investors need higher cap rates to justify the risk premium, which means lower property prices for the same income level.

Investors who bought properties at compressed cap rates when financing was cheap can find themselves holding assets that are worth less when they want to sell, not because the property income changed, but because market cap rate expectations changed. Coventry Enterprises LLC evaluates this risk when reviewing acquisition financing for investment properties, modeling what happens to the investment return if exit cap rates are higher than entry cap rates.

Cash Flow Math at Different Rates

The direct impact on a rental property is straightforward. A $400,000 property with a 25% down payment carries $300,000 in debt. At 5%, the annual principal and interest payment is about $19,300. At 7.5%, it's about $25,200. That's nearly $6,000 per year in additional carrying cost, which needs to come from higher rents, lower expense expectations, or lower purchase price.

Properties that cash flow at 5% may break even or run negative at 7.5%, particularly in markets where rents haven't risen proportionally to financing costs. Jack Bodenstein and Coventry Enterprises LLC model cash flow for investment property acquisitions at the actual current rate, not a hoped-for future rate, which is how some buyers rationalize deals that don't currently work.

Refinance Risk

Borrowers who financed investment properties at historic lows and face loan maturities or balloon payments in rising rate environments face a specific refinance risk: the new loan at current market rates may not be supportable by the property's current income at acceptable LTV ratios. This is particularly acute for commercial real estate with 5 to 7-year balloon maturities that were underwritten in low-rate environments.

Coventry Enterprises LLC includes refinance rate stress testing in commercial loan reviews precisely because the balloon maturity risk is real and predictable. Knowing that a balloon comes due in 5 years and current rates make refinancing difficult is information a borrower needs to plan around, ideally before committing to the original loan.

Timing Strategy and Rate Cycles

Attempting to time the market around rate cycles is largely futile for most investors. Rates move in unpredictable ways, and waiting for lower rates means passing on deals that may not be available when rates eventually fall. The better approach is ensuring that any deal acquired works at the current financing cost, with a conservative assessment of the exit environment. Deals that only work if rates fall are speculations, not investments.
