Investing in St. Simons Island, GA — Market Analysis
St. Simons Island is a high-basis market by Georgia standards, with a median home price around $750,000. St. Simons Island 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. Simons Island on a DSCR loan means putting a minimum of $150,000 down (20% of purchase price), leaving a loan amount of $600,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $4,195 per month. Add Glynn County property taxes of roughly $575/month, landlord insurance of about $575/month, and an HOA/master-association allowance of $320/month, and your all-in PITIA lands near $5,665/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in St. Simons Island should generate roughly $3,075/month in gross rent. Against a PITIA of $5,665, that produces an estimated DSCR ratio of 0.54x. 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. Simons Island is around $6,600/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 $4,752/month, or a DSCR ratio of 0.84x. 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 counties reassess investment property at fair market value after a sale and most metro-Atlanta counties apply a 40% assessment ratio to that value, so the tax line on your pro forma should be modeled off the price you pay rather than the prior owner's homestead-capped bill. In St. Simons Island specifically, effective property tax on investment property runs around 0.92% of value annually — about $6,900 a year at the median price — and landlord insurance near $6,900 a year.
On return metrics, St. Simons Island pencils to an estimated cap rate of 3.05% using a 62% NOI margin, and a gross rent multiplier of 20.3. Monthly cash flow on a long-term lease at 20% down is estimated at $2,590 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.
