Rental property math in San Antonio, TX

A typical San Antonio home is worth $273,806 and a typical single-family rental there gets $1,820 a month, 0.66% of the price. At 80% LTV and an assumed 7.25% rate, rent divided by the full payment is 0.95x. A DSCR loan needs 1.05x, which takes $2,003 of rent, $183 more than typical.

The DSCR on the typical San Antonio house

Loan: $273,806 × 80% = $219,045. At 7.25% over 30 years, principal and interest are $1,494 a month. Taxes: $273,806 × 1.21% = $3,314 a year, $276 a month. Insurance, assumed at 0.6% of value: $1,643 a year, $137 a month. Payment (PITIA): $1,907. DSCR: $1,820 ÷ $1,907 = 0.95x.

Rent that clears 1.05x: $1,907 × 1.05 = $2,003.

Even a rate one point lower, 6.25%, only gets the typical house to 1.03x, so in San Antonio the deal has to come from the house, not the rate.

What it would take to reach 1.05x

Find $183 more rent a month: a house that rents above the metro's typical $1,820, or a 2-4 unit property where the units add up to $2,003.
Pay less: at today's typical rent, 80% LTV works on a purchase of about $248,828 or below (9% under the typical price), counting the lower taxes and insurance on a cheaper house.
Borrow less: on the typical house the rent supports a loan of $193,539, about 71% LTV, so you would put $80,267 down instead of $54,761.

These are metro-wide typicals, not any one property. The lender's appraisal sets the value and market rent for the house you buy, and the lender uses the lower of the lease and that market rent (90% of it on a vacant unit). The rate is a placeholder for the math, not a quote. How the numbers are built.
