When investing in rental properties, obtaining financing is crucial yet challenging. A 40 year mortgage extends repayment duration, lowering periodic dues, making investment property purchases more feasible. With property values and rental incomes often inflation-linked, longer mortgages better match investment horizons. However, investors tradeoff greater interest costs and face risks like rising rates. Choosing between adjustable-rate and fixed-rate mortgages involves balancing cost savings against interest rate risks over the long-term holding period.

40 year mortgage interest rates slightly higher than 30 year loans
40 year mortgages typically have interest rates 0.125% to 0.25% higher than 30 year loans. The longer repayment term entails additional interest costs for the lender. However, the longer tenure lowers periodic installments, improving repayment affordability. This helps investors taking on higher leverage to fund downpayments. The loan-to-value ratio impacts mortgage rates too – higher leverage means higher perceived credit risks hence higher rates. Investors should model periodic expenses like property taxes and insurance on top of mortgage installments when budgeting purchase financing.
Adjustable rate mortgages cost less initially but face interest volatility
Adjustable rate mortgages (ARMs) offer lower initial rates for 3-10 years before the interest rate resets periodically based on benchmark indicators like LIBOR or US Treasury yields. Opting for ARMs allow investors to benefit from current low rates. However, when rates eventually rise, periodic installments will increase, impacting property cash flows. ARMs hence face interest rate risks over the extended investment horizon. Investors must stress test affordability of installments after rate resets to avoid excessive volatility in property incomes versus expenses.
Fixed rate 40 year loans offer predictable installments despite higher costs
Unlike adjustable rate loans, 40 year fixed rate mortgages lock in a constant interest rate for the entire repayment duration. This insulates the investor from fluctuating rate cycles over the long holding period. However, current fixed rates are anchored to long-term benchmarks like 10-year US Treasury yields, hence fixed rate loans cost more upfront. Investors pay a premium for rate stability. Still, the predictable installments better match the investment timeline for buy-and-hold property investors seeking income stability.
Mortgage qualification criteria excludes interest-only investor loans
High net worth property investors sometimes prefer interest-only mortgages to maximize leverage capacity while dedicating rental income solely to interest dues. However, under current US regulations, interest-only loans do not qualify towards lender benchmarks like maximum debt-to-income ratios. Lenders also scrutinize borrower liquid reserves besides property appraisals when approving 40 year investment mortgages. Hence, investors seeking long investment horizons may need to use higher proportions of equity instead of debt for financings.
Mortgage of investment residence requires stricter lender underwriting
Unlike primary home purchases, investment property mortgages undergo stricter lender criteria given the asset is intended for rental income, not owner-occupation. Lenders evaluate metrics like cash-on-cash returns to gauge repayment feasibility over decades. Moreover, property investors tend to pursue riskier strategies like negative gearing to reap tax advantages. Hence lenders impose tighter standards for debt servicing capacity, credit scores, income buffers and risk profiling when approving investment residence mortgages to manage delinquency risks.
40 year mortgages optimize leverage capacity for property investors by lowering periodic expenses through extended tenures. However, longer horizon adjustable rate mortgages face larger interest volatility while fixed rate variants have significantly higher costs. Mortgage approvals also require stricter due diligence by lenders given investment assets pose distinct risks. Investors should stress test affordability under various rate and appreciation scenarios when structuring buy-and-hold financings.
