Investing in St. Marys, GA — Market Analysis
St. Marys is one of the lower-basis entry points in Georgia, with a median home price around $300,000. St. Marys is a coastal market, which changes the underwriting in two specific ways: insurance is a far larger line item than an inland comp, and windstorm or flood coverage may be written separately from the hazard policy. Both flow directly into your DSCR ratio.
Buying a rental property in St. Marys on a DSCR loan means putting a minimum of $60,000 down (20% of purchase price), leaving a loan amount of $240,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $1,678 per month. Add Camden County property taxes of roughly $230/month, landlord insurance of about $230/month, and an HOA/master-association allowance of $180/month, and your all-in PITIA lands near $2,318/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in St. Marys should generate roughly $1,500/month in gross rent. Against a PITIA of $2,318, that produces an estimated DSCR ratio of 0.65x. That is well below the 1.0 threshold on a long-term lease, which is typical for a market at this price point. Financing here generally works one of three ways — a larger down payment, a no-ratio DSCR product, or qualifying on short-term rental revenue instead of long-term rent.
If you intend to operate the property as a short-term rental, estimated gross nightly revenue in St. Marys is around $2,250/month across a full year. Lenders do not credit gross STR revenue dollar-for-dollar — they typically haircut it 25%–30% for vacancy, cleaning, platform fees, and management. Applying a 28% haircut gives an effective $1,620/month, or a DSCR ratio of 0.70x. Even on short-term revenue this is a tight file, so plan on a larger down payment or a no-ratio structure.
Two Georgia-specific items to build into your model: Georgia is a non-judicial foreclosure state with fast eviction timelines, which is why institutional single-family rental operators concentrated in metro Atlanta. North Georgia mountain counties (Fannin, White, Lumpkin) drive the state's short-term rental revenue. In St. Marys specifically, effective property tax on investment property runs around 0.92% of value annually — about $2,760 a year at the median price — and landlord insurance near $2,760 a year.
On return metrics, St. Marys pencils to an estimated cap rate of 3.72% using a 62% NOI margin, and a gross rent multiplier of 16.7. Monthly cash flow on a long-term lease at 20% down is estimated at $818 negative. Negative cash flow at 20% down is common in appreciation-led markets; investors here typically increase the down payment, buy below median, add a unit, or run the property short-term to close the gap.
