• Three-unit property: $1,288,800

Homes in downtown Charleston, Mount Pleasant, Sullivan's Island, and Isle of Palms regularly exceed these thresholds, so jumbo mortgages are the usual form of financing in these markets.

Borrowers with strong qualifications can obtain a jumbo loan in South Carolina of several million dollars. The ceiling for a given file is a function of credit score, loan-to-value ratio, and reserves. Higher scores and deeper reserves usually bring lower jumbo rates and better terms.

No. A credit score of 750 or above earns the strongest jumbo pricing. A borrower with a somewhat lower score may still qualify when the file offers compensating strengths, such as more money down or large liquid reserves.

Yes. Jumbo Non-QM programs exist for this purpose, and the two most used are bank statement loans and asset depletion loans. Business owners, consultants, and retirees buying in Mount Pleasant or on the islands may qualify without W-2s or conventional tax returns. South Carolina bank statement loans calculate income from 12 or 24 months of deposits, and jumbo loan amounts reach $7M.

Jumbo lenders finance single-family homes, warrantable and non-warrantable condos, townhomes, and 2–4 unit properties in the Charleston area. We arrange jumbo financing for a South of Broad single house, an I'On residence, a Wild Dunes villa, or a Kiawah Island home. Coastal properties in a mapped flood zone require flood insurance, and we account for the premium when we qualify the loan.

Jumbo rates in the Charleston area are frequently in line with conventional rates and occasionally below them. Lenders compete for strong jumbo borrowers in established markets such as Mount Pleasant and Daniel Island.

It may be, and the length of time you plan to own the home decides the question. A 5/1 or 7/1 jumbo ARM fixes the rate for five or seven years and often prices below a 30-year fixed. The lower early payment can help on a Mount Pleasant or Isle of Palms purchase, which is one reason ARMs have returned for jumbo borrowers. Executives who relocate often and buyers who plan to refinance are the common candidates. Holding period drives the decision, so a borrower should weigh whether an ARM fits a planned sale.

Credit, reserves, and the appraisal all enter the decision, and maximum loan-to-value is commonly about 80% on a primary home and lower on very large loans. Owners in Mount Pleasant, on James Island, and on the peninsula can draw on equity through a jumbo cash-out refinance. The existing mortgage is retired by a larger jumbo loan, and the owner takes the difference in cash. Charleston homeowners with VA entitlement may be able to borrow a higher share of value through a VA cash-out refinance or a VA jumbo cash-out refinance. Monthly mortgage insurance is absent from both VA loans.

Eligible veterans and active-duty service members, including personnel stationed at Joint Base Charleston, may be able to use a VA loan above the conventional limit. For those who qualify, a higher-priced home may be purchased with $0 down and no monthly PMI. A borrower with full entitlement may use VA jumbo loans without a set loan limit.

Yes. A jumbo refinance can lower the rate, exchange an ARM for a fixed loan, or take equity out of a high-value Charleston home. Retired owners may also qualify for the new loan with an asset depletion loan in South Carolina, which counts investment balances as income.

A denial at one bank tends to say more about its overlays than about the borrower's capacity to repay. Treatment of bonus income, RSUs, business income, and large asset balances is far from uniform among wholesale jumbo lenders. A broker can move the same file to a lender whose guidelines match it. Buyers under contract still have options after a jumbo loan denial in South Carolina.

Jumbo lenders generally require 10% to 20% down on a primary residence in Charleston County. Borrowers with the strongest credit and reserves receive the lowest down payments, while second homes and investment properties call for more. Lenders weigh the reserves left after closing as heavily as the down payment. Minimums are set program by program, and jumbo and Non-QM mortgage down payments rise or fall with credit, occupancy, and loan size.
