Rental property math in Charleston, SC

The DSCR on the typical Charleston house

Loan: $437,474 × 80% = $349,979. At 7.25% over 30 years, principal and interest are $2,387 a month. Taxes: $437,474 × 0.37% = $1,625 a year, $135 a month. Insurance, assumed at 0.6% of value: $2,625 a year, $219 a month. Payment (PITIA): $2,742. DSCR: $2,575 ÷ $2,742 = 0.94x.

Rent that clears 1.05x: $2,742 × 1.05 = $2,879.

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

What it would take to reach 1.05x

Find $304 more rent a month: a house that rents above the metro's typical $2,575, or a 2-4 unit property where the units add up to $2,879.
Pay less: at today's typical rent, 80% LTV works on a purchase of about $391,322 or below (11% 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 $307,581, about 70% LTV, so you would put $129,893 down instead of $87,495.

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.
