South Carolina’s development pipeline is as active as anywhere in the Southeast. Charleston’s suburbs are absorbing new townhome communities faster than builders can complete them, Myrtle Beach’s Horry County issued over 17,500 residential permits in the most recent fiscal year, and Greenville has quietly become one of the most in-demand smaller metros for spec development in the region. If you’re a developer looking to break ground in South Carolina, the opportunity is real — and so are the financing specifics you need to get right before you approach a lender.
This guide covers how South Carolina construction loans work for ground-up developers: loan terms, LTC limits, draw schedules, what lenders actually require, and what makes the state’s major markets distinct from a financing standpoint.

Why South Carolina Is Attracting Ground-Up Developers
The fundamentals driving development activity in South Carolina are straightforward: in-migration is strong, housing supply is still catching up to demand, and land remains comparatively affordable against many other Sunbelt states.
In the Charleston metro, new construction is concentrated in Summerville, Nexton, and Moncks Corner — areas where land is still available and suburban infrastructure is building out. Mount Pleasant’s median home price reached $913,000 as of late 2025, up 13.1% year over year, which has pushed more buyers into new construction communities where pricing can be right-sized. In Myrtle Beach’s Horry County, the latest permit data shows 17,552 residential permits issued in the most recent fiscal year, a figure that has held relatively steady — reflecting sustained but not overheated demand.
For developers, what matters most is exit velocity. A spec home or townhome in Charleston’s suburbs or the Myrtle Beach coastal corridor can typically move within 30-90 days of completion if priced correctly. That’s the exit timeline that makes construction financing viable without becoming a carry-cost problem.
According to the Mortgage Bankers Association’s 2026 CREF Forecast, total commercial mortgage originations are projected to reach $805.5 billion in 2026 — a 27% increase from 2025 — driven in part by accelerating development activity in markets like the Carolinas.
How South Carolina Construction Loans Work
Ground-up construction loans are short-term, interest-only financing products designed to cover the cost of building from land acquisition through project completion. They’re not permanent financing — they’re the bridge that gets you from shovel in the ground to a finished, sellable or rentable asset.
Here’s what a typical non-agency construction loan in South Carolina looks like:
- Loan term: 12-24 months, interest-only throughout the construction period
- Loan-to-cost (LTC): Up to 80-85% for experienced developers with strong exit strategies; some programs reach 90% LTC on larger deals
- Loan-to-completed value (LTCV): Most lenders cap this at 65-70%, regardless of LTC. LTCV is often the binding constraint — run both calculations before you assume your loan amount
- Rates: Roughly 9.5-12% in the current rate environment, depending on LTC, credit, and market, plus 1.5-3 points origination upfront
- Interest charges: You only pay interest on drawn funds, not the full loan commitment — so early-stage carry costs are lower than the rate alone suggests
- Draws: Funds are released in phases tied to project milestones, with third-party inspector verification before each draw
For a detailed look at how draws are structured and what triggers each disbursement, see our guide on how construction draw schedules work.
Loan Requirements: What Lenders Look For
South Carolina construction loan requirements vary by lender and deal type, but most non-agency programs expect:
- Credit score: 650 minimum, with most lenders preferring 680-700+. Below 660, expect higher points or a reduced LTC offer
- Developer experience: Prior ground-up completions matter. First-time builders can qualify at lower LTC with an experienced, licensed general contractor under contract
- Down payment / equity: Budget for 15-25% of total project costs out-of-pocket. This is your skin in the game — lenders underwrite based on how much you stand to lose if the project goes sideways
- Shovel-ready status: Most lenders won’t commit capital until the project is fully entitled — permits pulled or in process, plans approved, and GC selected
- Exit strategy: Either a credible sale pipeline (comps to support pricing) or a pre-approved DSCR refinance path. Lenders are making a 12-24 month bet that you’ll pay them out. Make that path specific
- Project budget: Fully itemized, including contingency. Budget gaps get caught in underwriting. Include soft costs — architect fees, permit costs, insurance
Charleston vs. Myrtle Beach: What Makes Each Market Different
Charleston offers higher price points, more supply-constrained submarkets, and a more institutionally sophisticated buyer pool. Mount Pleasant, James Island, and the North Charleston submarkets each have their own absorption dynamics. New construction in the $400K-$700K range moves fastest. Luxury spec above $900K can sit longer and carries more carry-cost risk — build that into your pro forma timeline.
Lenders are generally comfortable in the Charleston market, which can translate to more flexible terms for experienced local developers. Competition for desirable land is real, though, and land costs have moved materially over the past 24 months.
Myrtle Beach / Horry County features a broader price band, more buyer variety (retirees, vacation buyers, primary residents), and strong rental demand that creates DSCR refinance exit options post-construction. Coastal proximity adds value but also adds lender hesitation around flood zone positioning — FEMA flood zone designation affects appraised value and loan sizing. Know your flood zone before you go to a lender; it will come up in underwriting.
Townhome and condo projects in the Myrtle Beach corridor are financeable, though condo construction carries additional requirements around pre-sales. See our overview of condo construction loans for the specifics on presale thresholds and how lenders think about attached-unit development.
Greenville is worth a mention for developers looking beyond the coast. Lower land costs, a strong job market anchored by BMW, Michelin, and a growing tech presence, and less competition from national homebuilders than Charleston or Myrtle Beach. Entry price points in the $280K-$450K range have strong absorption. I’ve seen increasing out-of-state developer interest in Greenville over the past 18 months — usually a leading indicator that land prices are about to move.

From a Recent Deal
From a recent deal: I worked with a developer on a 6-unit townhome project in the Summerville market — his first multi-unit build after completing two single-family spec homes. Total project cost came in just under $2.1M. We structured a non-agency construction loan at 80% LTC, but the 70% LTCV cap on the $2.1M completed value estimate worked out to $1.47M — so LTC wasn’t the binding constraint, LTCV was. The developer funded the gap plus closing costs from proceeds on his prior two sales. The loan ran 18 months at interest-only, the project went through six draws over 14 months, and all six units sold within 45 days of the final CO. The economics worked cleanly. The key was running the LTCV math before we approached the lender, not after.
What to Bring When You Approach a Lender
The faster you get a lender to “yes,” the sooner you can move on land. Most non-agency construction lenders in South Carolina will need upfront:
- Fully executed or site-controlled purchase agreement for the land (or proof of existing ownership)
- Construction cost breakdown — itemized by trade, with a contingency line
- Architectural plans (preliminary is acceptable early in the conversation; full plans are needed for a commitment letter)
- Signed GC contract or a letter of intent from a licensed South Carolina general contractor
- Pro forma: projected sale price supported by comparable sales, project timeline, total cost, and projected developer profit
- Borrower personal financial statement and two years of tax returns
- Photos and brief description of prior completed projects if you have development experience

Frequently Asked Questions
How long does it take to close a construction loan in South Carolina?
Most non-agency construction loans close in 21-30 days for well-prepared borrowers — full plans, a GC contract, and a signed purchase agreement in hand at the time of application. Bank programs typically run 45-60 days due to committee approval processes. If you’re under contract on land with a tight closing window, non-agency is usually the faster path.
Can I use a construction loan to build rental properties in South Carolina?
Yes. Build-to-rent is an active use case, particularly in the Myrtle Beach and Columbia markets where short-term rental and long-term rental demand are both strong. The exit strategy shifts from a sale to a DSCR refinance at certificate of occupancy. We structure bridge-to-DSCR exits frequently for build-to-rent developers in SC.
Do lenders require presales for South Carolina construction loans?
For single-family spec homes and most townhome projects, presales are not required — lenders underwrite to the completed value and your sale exit strategy. For condominium projects, presale thresholds typically apply — usually 20-30% of units under contract before funding.
What’s the difference between LTC and LTCV, and why does it matter?
LTC (loan-to-cost) is your loan amount divided by total project cost. LTCV (loan-to-completed value) is your loan divided by the appraised after-construction value. Most lenders cap both, and LTCV often becomes the binding constraint. Example: $1.5M cost, $1.8M completed value — 85% LTC gives you $1.275M, but 70% LTCV gives you $1.26M. Run both numbers before assuming your loan size.
