How this scenario is calculated

Annual operating income is rent after vacancy, management, maintenance, taxes, insurance, HOA and other operating costs, before financing and capital reserves. Cap rate divides annual operating income by purchase price. Estimated monthly cash flow assumes an all-cash purchase: rent after vacancy, management, maintenance, taxes, insurance, HOA, other operating costs and capital reserves. No mortgage payment is deducted. The mortgage calculator is separate; loan payments would reduce cash flow for a financed purchase. One-time acquisition costs, renovations, income taxes, depreciation and appreciation are excluded.

Mortgage payment calculator

Explore financing separately. These loan settings do not change the all-cash investor outlook.

Mortgage assumptions

Down payment (%) Interest rate (%) Loan term

20% down and 7% interest are illustrative starting values.

Estimated monthly principal & interest—Loan payment only. Excludes property taxes, homeowners/flood insurance, mortgage insurance and HOA dues.

About this payment estimate

Based on a fixed-rate, fully amortizing loan with monthly payments and the price, down payment, interest rate and term you select. The interest rate is an example, not a current rate offer or APR; APR includes certain loan costs. This is an illustration, not a Loan Estimate, approval, offer of credit or commitment to lend.

Your actual payment, rate and eligibility depend on your lender, credit, loan program and property. Closing costs, points, prepaid expenses and lender fees are not included. Taxes and insurance may change, and mortgage insurance may be required, particularly with a down payment below 20%. Ask your lender for a Loan Estimate and a complete monthly payment including applicable taxes, insurance and fees.

Dollar results are rounded to the nearest cent; calculations retain precision until display. A cash purchase has no loan payment but still has ownership costs. Understand your total home payment (CFPB).
