The Palmetto Stack + the Flood-Insurance Gotcha
Palmetto DPA: 0% second mortgage, forgivable over ~10 years of occupancy — covers the 3.5% down and a slice of closing. SC's affordable stock means it covers more of the deal than coastal states.
The flood trap: homes in FEMA high-risk zones REQUIRE flood insurance before closing — $60-300+/mo that lands on your DTI at the worst time. A qualifying deal can die on the insurance line, not the loan.
Income caps ~$100-135K by county — pass the cap AND Palmetto's purchase limits. Charleston's hottest listings can clear FHA but fail the agency gate.

The SC Reality Check: Coastal Premium, Inland Value
Charleston vs Columbia is a 2x price gap. Charleston metro median ~$420K as of late 2026 vs Columbia ~$250K and Greenville ~$320K — all under the ~$524K floor, but only inland SC gives FHA buyers true room. Charleston's pricing means the state DPA matters most on the coast.
SC Housing Palmetto Home Advantage is the lane. ~4% deferred assistance (forgivable over ~10-15 years depending on vintage) stacks with FHA — on a $280K Columbia purchase, ~$11K covers down payment plus closing buffer. The forgivable structure makes it one of the south's cleanest programs.
The flood-insurance trap is real: coastal SC's flood zones add ~$1,500-4K/yr to PITI on FHA deals — the DTI that qualified you pre-quote may fail post-flood-quote. Check the FEMA map BEFORE you write the offer, not during underwriting.
5 FHA Gotchas in South Carolina
1. Flood insurance eats DTI
In FEMA high-risk zones it's mandatory pre-close — $100-300+/mo near Charleston and Myrtle Beach. Run the flood-zone check BEFORE offering; it kills more coastal deals than credit does.
2. Wind/hail zones add up
Coastal SC adds windpool coverage on top of standard homeowner's — stack flood + wind + hazard and the insurance load rivals the taxes.
3. Lifetime MIP under 10% down
3.5% down = MIP for the loan's life. The refi exit at 20% equity is fast on SC's appreciating metro stock — but watch the Palmetto forgiveness clock.
4. Palmetto-state overlays
HUD allows 580; SC lenders overlay 620-640, Palmetto runs 640. A 615 denial is a lender choice — shop the participating list.
5. Beach-condo investor ratios
Beach condo projects need FHA approval or single-unit approval — many Myrtle Beach buildings fail the investor-ratio test.
Frequently Asked Questions
Q1. What are the FHA loan limits in South Carolina for 2026?
Nearly all 46 SC counties sit at the national floor (~$541K for 2026); Charleston metro gets a slight bump. With SC median prices under the ceiling almost everywhere, the limit rarely blocks a deal. Verify your county at HUD.gov.Get FHA pre-approved →
Q2. Can I stack SC Housing Palmetto with FHA?
Yes — the standard SC play. Palmetto pairs FHA first mortgages with forgivable DPA: a 0% second that burns off over ~10 years of occupancy. On a $300K Greenville starter it covers the $10.5K down plus closing help.Check Palmetto stacking →
Q3. What credit score do I need for FHA in South Carolina?
HUD floor: 580 for 3.5% down, 500-579 at 10%. SC reality: lender overlays at 620-640, and Palmetto pairs run 640. At 640+ the full stack opens cleanly.
Q4. How does FHA MIP work on an SC purchase?
1.75% upfront financed + ~0.55% annual monthly. On $300K: ~$5.25K rolled in + ~$135/mo. With 3.5% down it's lifetime — the exit is conventional refi at 20% equity, typically 5-7 years in metro markets.Compare FHA vs conventional →
Q5. Is flood insurance required on FHA loans in SC?
If the home sits in a FEMA high-risk flood zone, yes — lenders require it before closing, and it adds $60-300+/mo to your payment on the coast. Always run the flood-zone check BEFORE making an offer near Charleston or the coast — it can kill the DTI.
Q6. What if my score is under 580?
Below 580 rules out FHA and Palmetto. Rebuild fast: utilization under 30% plus report disputes typically adds 20-40 points within 60 days — free HUD counseling runs across the Carolinas.Spike my score →
