Investing in Mount Pleasant, SC — Market Analysis
Mount Pleasant is a high-basis market by South Carolina standards, with a median home price around $780,000. Mount Pleasant 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 Mount Pleasant on a DSCR loan means putting a minimum of $156,000 down (20% of purchase price), leaving a loan amount of $624,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $4,363 per month. Add Charleston County property taxes of roughly $637/month, landlord insurance of about $598/month, and an HOA/master-association allowance of $320/month, and your all-in PITIA lands near $5,918/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in Mount Pleasant should generate roughly $3,150/month in gross rent. Against a PITIA of $5,918, that produces an estimated DSCR ratio of 0.53x. 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 Mount Pleasant is around $4,725/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 $3,402/month, or a DSCR ratio of 0.57x. Even on short-term revenue this is a tight file, so plan on a larger down payment or a no-ratio structure.
Two South Carolina-specific items to build into your model: South Carolina taxes owner-occupied property at a 4% assessment ratio but investment property at 6%, so investor carrying costs run meaningfully higher than an owner-occupant comp on the same street. In Mount Pleasant specifically, effective property tax on investment property runs around 0.98% of value annually — about $7,644 a year at the median price — and landlord insurance near $7,176 a year.
On return metrics, Mount Pleasant pencils to an estimated cap rate of 3.00% using a 62% NOI margin, and a gross rent multiplier of 20.6. Monthly cash flow on a long-term lease at 20% down is estimated at $2,768 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.
