Vacation Home Mortgage Options

DSCR stands for debt service coverage ratio. In Visio’s residential formula, monthly qualifying rent is divided by monthly principal, interest, taxes, insurance and association dues, often abbreviated as PITIA. A ratio of 1.0 means that rent equals those specified obligations; it does not establish profitability after every operating expense. The approach emphasizes property income rather than personal earnings, but property, credit and documentation requirements still apply. Down-payment requirements and acceptable ratios vary by lender and product. Personal-use terms also need product-specific confirmation: a DSCR calculation alone says nothing about whether you can occupy the home.

DSCR is not the only financing approach that can consider short-term rental income. Fannie Mae’s September 2026 guidance covers legally permitted, one-unit investment properties used as short-term rentals. For purchases, evidence can include a long-term comparable-rent schedule or validated short-term rental data from MLS or property-management companies, including three comparables and historical rented days. An advertised income projection alone is not equivalent to that documentation. The purchase calculation applies 50% to documented gross rent before subtracting housing expenses, with restrictions on how the result can be used to qualify. It is not the standard 75% rent calculation.

Nationality alone does not determine a buyer’s financing route. Fannie Mae permits mortgages to qualifying lawful permanent and non-permanent U.S. residents on the same terms as U.S. citizens. Nonresident UK and other international buyers may have specialist international-borrower or foreign-national DSCR options, subject to program eligibility. HSBC says qualifying international applicants need not have U.S. credit history, although it may obtain an international credit report. As one lender-specific example, Acra’s foreign-national DSCR checklist includes an unexpired passport, foreign-bank statements and/or a credit-reference letter, documented reserves, an appraisal and comparable-rent documentation. Entity purchases can require additional documents. These examples illustrate possible routes, with eligibility and documentation requirements depending on the lender and the applicant’s circumstances.
