How much do I need to put down on a single-family rental in Sullivan's Island, SC?

20% is the working minimum on a DSCR loan for this product — about $500,000 at the $2,500,000 price point modeled here — plus closing costs of roughly 2%–4% and three to six months of PITIA in reserves ($54,789 to $109,578). Putting more down improves the ratio and moves you into a better pricing tier, which is often the cheapest way to buy down the rate.

What DSCR ratio does a single-family rental in Sullivan's Island hit?

At the median basis modeled on this page, roughly 0.43x — $7,850 of creditable monthly income against $18,263 of PITIA. Most lenders want 1.0x or better for base pricing, several fund to 0.75x with a rate add-on, and no-ratio products exist for files that do not cash-flow at all. The ratio is property-specific, so the number on your address will differ.

Can I close a single-family rental in Sullivan's Island in an LLC?

Yes. DSCR loans are business-purpose loans, so title in an LLC, LP or trust is standard and does not change pricing. You will personally guarantee the note and provide the operating agreement, EIN and certificate of good standing. Conventional investor financing does not allow entity title, which is one of the main reasons investors choose DSCR even when they could document income.

Do I need a signed lease to close on a rental in Sullivan's Island?

No. A vacant single-family property qualifies on the appraiser's Form 1007 market rent schedule alone. If a lease is already in place, the lender compares it to the 1007 and uses the lower of the two — so an inherited below-market tenant can hold your ratio down until that lease turns over.

Single-Family Rental investing in Sullivan's Island

Single-family rentals are the cleanest DSCR file you can write in Sullivan's Island. One unit, one lease, one Form 1007 market rent schedule, and the deepest set of sale and rent comps in the Charleston County appraisal market. Detached stock also carries the longest average tenancies, which is what actually protects the ratio you close at.

At the Sullivan's Island median of $2,500,000, a single-family rental prices near $2,500,000. Minimum down is 20% ($500,000), leaving a loan of $2,000,000. Estimated all-in PITIA runs about $18,263 per month.

The Sullivan's Island ratio math on this product

A long-term lease should produce roughly $7,850/month in gross rent. Against a PITIA of $18,263, that is an estimated DSCR ratio of 0.43x. That is below the 1.0 threshold, which is normal at this basis. Financing here works one of three ways — more money down, a no-ratio DSCR product, or qualifying on documented short-term rental revenue.

Underwriting notes specific to detached rentals: the appraiser's Form 1007 and your signed lease are compared and the lower number is used, so a below-market inherited tenant will cap your ratio no matter what the market says. Budget 5% of gross rent for vacancy and 8%–10% for management even if you self-manage — a lender will not require it, but the file should still pencil with it.

Returns and structure

Return metrics at the Sullivan's Island median for this product: an estimated cap rate of 2.34%, and monthly cash flow of $10,413 negative at 20% down. Negative cash flow at the minimum down payment is common in appreciation-led markets; investors close the gap with a larger down payment, a purchase below median, an added unit, or a rate buydown. Note that the $2,000,000 loan amount exceeds the $806,500 conforming limit for Charleston County, so agency pricing is off the table and this is a jumbo DSCR file.
