Charleston DSCR Loans: Financing Rentals in South Carolina's Priciest Market
Program and regulatory figures verified August 10, 2026. Details change; confirm your scenario with us.
Charleston is South Carolina's highest-price, strongest-rent metro, and its STR rules turn on the parcel's zone and category rather than one citywide number. Read the ordinance before the listing and the deal gets a lot clearer.
Can I get a DSCR loan in Charleston?
Yes: we lend on 1-4 unit rental property across the Lowcountry, from the peninsula and West Ashley to Mount Pleasant, James Island, Johns Island, and Daniel Island. The qualification is the property's rent against its full payment (PITIA), documented by the appraiser's rent schedule or your lease. Tax returns stay out of the file. The mechanics are covered in the South Carolina DSCR guide; this page is the Charleston layer.
The Charleston numbers (dated, because they move)
Charleston is the state's priciest metro, and the reported median depends on which compilation and month you read: roughly $615,000 in May 2026 by one source, with other mid-2026 reports landing between $675,000 and $710,000. Condos average about $495,742 and single-family homes about $697,295. Roughly 44% of households rent, inventory is up 5-14% year over year, and forecasts sit around 2-3% appreciation for 2026. These are wide ranges, so treat any single hard number skeptically, ours included, and we underwrite the specific address, not the metro average.
What rent do I need? A worked Charleston DSCR example
A DSCR loan qualifies on one ratio: the property's market rent divided by its full monthly payment (principal, interest, taxes, insurance, and any HOA, or PITIA). Charleston rent depends heavily on source and property type. Apartments average about $2,137 (RentCafe, August 2026). All-property-type rent averages roughly $2,900 to $3,000 (Zillow Rental Manager, July 2026). Single-family homes, the usual DSCR target, commonly run $2,750 to $3,350, with Charleston County single-family averaging near $2,750 across bedroom counts. Here is how those numbers play out on a mid-range single-family rental.
| Line | Illustrative figure |
|---|---|
| Purchase price | $450,000 (below the metro median) |
| Down payment (25%) | $112,500 |
| Loan amount | $337,500 |
| Market rent, monthly | $2,900 (Zillow Rental Manager, all types, July 2026) |
| All-in monthly payment (PITIA)* | ~$3,050 |
| DSCR (rent ÷ PITIA) | 0.95 |
*We don't quote a rate on this site. The PITIA figure is illustrative and folds in Charleston's 6% assessment-ratio taxes and landlord insurance, which run higher here than a listing's owner-occupied estimate.
That 0.95 lands just under the 1.0 most programs want, which is honest for retail Charleston pricing: high purchase prices and the 6% tax line squeeze the ratio. The fix is usually one of four moves. Put more down, so the payment drops. Target a higher-rent or small 2-4 unit property, where combined rents clear the payment. Bring a signed lease above market to document the rent. Or use a no-ratio program that some lenders offer at a lower LTV. We run all four against your capital before you write the offer.
The Charleston tax line deserves its own warning. A rental is assessed at the 6% ratio with no school-operating exemption, so on a Charleston property the tax inside your PITIA runs far above the owner-occupied estimate a listing shows: 2.5 to 3 times an owner-occupant's on the same house. At Charleston price points that gap is real money against the ratio. Run it with the 6% tax trap page.
The Charleston STR rules, honestly
Charleston does not publish a single citywide permit cap the way Folly Beach (800) or Mount Pleasant (400) do. Instead it regulates by zone and category: the STR Overlay Zone (which includes Cannonborough-Elliotborough) allows commercially-zoned properties to pursue Commercial STR Permits, one permit equals one unit, and a lot tops out at 9 STR units; off-peninsula categories covering West Ashley, Johns Island, James Island, and Daniel Island add an off-street-parking requirement. We frame it qualitatively on purpose: confirm the current rules on the parcel with the city before you write the offer (as of August 10, 2026).
One live item: the city floated moving from the hard-to-enforce "4 unrelated adults" occupancy standard to a flat 8-guest cap per unit, and on July 15, 2026 the Planning Commission unanimously ruled the amendment "not ready" for City Council after neighborhood pushback. The 4-unrelated-adults rule remains current law. This is the highest-recency item on the whole site, so we re-check it before every Charleston STR deal. Full picture and every other jurisdiction: STR rules by city.
2026 DSCR program ranges (dated)
These are the levers a Charleston DSCR file turns on. They are ranges, not quotes, and they move by program and by month, so treat them as the shape of the box rather than a rate sheet. Verified August 10, 2026.

| Credit floor | ~620 to 660 FICO |
| Reserves | ~2 to 6 months of payments |
| Personal income / DTI | None. No W-2s, no tax returns, no DTI calc |
| Property types | 1 to 4 units, condos, and eligible short-term rentals |
Three things investors get wrong about DSCR
Three corrections come up on almost every Charleston call.
- "I need to show income." No. A DSCR loan reads the property's rent, not your paystubs or returns. There is no personal debt-to-income calculation in the file.
- "First-time investors can't get one." Many programs have no prior-landlord-experience requirement, so a first rental can be a DSCR purchase.
- "Airbnb income won't count." On a permitted Charleston short-term rental, projected or documented STR revenue is often usable, which can lift a file that misses on long-term rent. The catch is the parcel's STR eligibility, not the loan.

Frequently asked questions
What's the Charleston, SC housing market like for investors in 2026?
Priced high and reported in a range: roughly $615,000 median in May 2026, with other mid-2026 compilations landing between $675,000 and $710,000 depending on source and month. Condos average about $495,742, single-family about $697,295, and roughly 44% of households rent. Forecasts sit near 2-3% appreciation. We underwrite the specific address, not the metro average.
Can I get a DSCR loan in Charleston?
Yes, Lowcountry-wide, on 1-4 unit rental property. The property's rent-to-payment ratio qualifies the loan; 20-25% down and 620-660 credit floors are typical, and you close in an LLC at the attorney's table. We lend on the peninsula, West Ashley, James and Johns Islands, Mount Pleasant, and Daniel Island.
Are short-term rentals legal in Charleston in 2026?
Yes, with a permit, but Charleston regulates by zone and category rather than one citywide cap: the STR Overlay Zone allows commercial STR permits, one permit per unit, up to 9 units per lot. The proposed flat 8-guest occupancy cap was ruled 'not ready' for City Council on July 15, 2026, so the 4-unrelated-adults standard still governs (as of July 2026). Confirm the parcel's category with the city.
Does Charleston's 6% property tax ratio really cost that much more?
Yes. A rental is assessed at 6% with no school-operating exemption; the owner-occupant next door pays at 4% with it. On the identical Charleston house, the investor's tax bill routinely runs 2.5 to 3 times an owner-occupant's, and that sits inside your DSCR payment. Listing-site tax estimates usually show the 4% figure, so we model the real one.
What monthly rent do I need for a DSCR loan in Charleston?
Enough for the rent to cover the full payment (PITIA). Charleston rents run wide by source and type: apartments average about $2,137 (RentCafe, August 2026) and all-property-type rent averages about $2,900 to $3,000 (Zillow Rental Manager, July 2026), with single-family homes commonly $2,750 to $3,350. At retail Charleston prices a single-family DSCR can land just under 1.0, so a larger down payment, a higher-rent or small multi-unit property, or a no-ratio program is often the fix. We underwrite the specific address, not the metro average.
