Cómo evaluar una propiedad de alquiler en EE.UU. desde el extranjero

When evaluating a U.S. rental property, most investors focus on three numbers: net operating income (NOI), cap rate, and cash-on-cash return. Each answers a different question. NOI tells you what the property produces before financing. Cap rate lets you compare properties regardless of how they are financed. Cash-on-cash return measures what your actual equity investment earns after debt service.

NOI is annual rental income minus annual operating expenses. Operating expenses include property management fees, insurance, property taxes, repairs and maintenance, vacancies, and HOA dues if applicable. NOI does not include mortgage principal and interest. A property with strong gross rent but high expenses can have a weaker NOI than it first appears.

Cap rate — capitalization rate — is NOI divided by the purchase price. It expresses the property's yield as if it were purchased with all cash. A higher cap rate generally indicates more income relative to price, but it often reflects higher risk, lower quality location, or less competitive market conditions. A lower cap rate often means more competition, lower perceived risk, and possibly stronger appreciation potential.

Cap rates vary significantly by market, neighborhood, property type, and condition. A cap rate that looks attractive in one city may be normal or even low in another. Use cap rate as a comparison tool within a market or asset class, not as an absolute standard. Always verify the income and expense assumptions behind a seller's stated cap rate — they may not include full vacancy allowance, realistic management fees, or accurate repair reserves.

Cash-on-cash return divides annual pre-tax cash flow — NOI minus annual debt service — by the total equity invested, including the down payment and closing costs. It reflects the actual return on the money you put in, accounting for your mortgage. If a DSCR loan has a high interest rate, it reduces cash-on-cash return even if NOI is strong.

For foreign investors using leverage, be conservative with assumptions. Use current rates from real lender conversations, not theoretical rates. Build in a vacancy allowance of at least 5 to 10 percent of annual rent. Include a capital reserve for repairs and replacements — a common rule of thumb is setting aside a percentage of rent monthly. The more conservative your projections, the fewer surprises you encounter after closing.

Before making an offer, build a simple spreadsheet with actual numbers: gross rent, vacancy allowance, all operating expenses, mortgage payment, and the resulting cash flow. Then stress test it: what happens if rent drops 10 percent? What if the property is vacant for two months? What if a major repair is needed in year one? A property that still makes sense under stress scenarios is a more durable investment than one that only works at optimistic projections. Consult a qualified financial advisor or accountant to review your analysis before committing.
