Down Payment Assistance in South Carolina: Charleston Buyer's Guide to Getting to the Closing Table in 2026
A large down payment is not the only path to homeownership in Charleston. For many buyers, the bigger challenge is covering the down payment, closing costs, prepaid taxes, and insurance at the same time.
South Carolina homebuyers may have access to state housing programs, forgivable second liens, gifts from family, seller contributions, and lender-specific assistance. When these options are paired correctly with an FHA, VA, USDA, or conventional loan, they may significantly reduce the amount of money you need to bring to closing.
This guide explains how down payment assistance works in 2026 and what Charleston-area buyers should know before choosing a program.
Start With the Right Assistance Program
Down payment assistance, often called DPA, is usually designed to help with your upfront homebuying costs. Depending on the program, assistance may be structured as a grant, a deferred loan, or a forgivable second mortgage.
The most important distinction is that not every assistance option is free money. Some programs require repayment if you sell the home, refinance, or stop using it as your primary residence before the required period ends.
SC Housing Homebuyer Program
The SC Housing Homebuyer Program is intended primarily for first-time buyers and families with low to moderate income. In general, a first-time buyer is someone who has not owned a principal residence during the previous three years. Veterans may qualify for an exception to that requirement.
The program offers:
- FHA, conventional, USDA, and VA financing options
- Competitive fixed-rate mortgage loans
- Forgivable down payment assistance
- Assistance that may help with the down payment, closing costs, and prepaid items
- A 0% interest second lien with no monthly payment under the current forgivable DPA structure
The current SC Housing Homebuyer Program describes a 15-year assistance term. If you remain in the home for the full term and continue meeting the program requirements, the lien may be forgiven. Charleston County income and sales price limits apply, so eligibility should be reviewed before you make an offer.
Palmetto Home Advantage
The Palmetto Home Advantage program is broader. It is available to first-time, move-up, and repeat buyers purchasing homes anywhere in South Carolina.
The program currently offers:
- Conventional, FHA, VA, and USDA loan options
- No first-time homebuyer requirement
- No sales price limit
- A minimum 640 credit score
- Forgivable assistance options of 0%, 3%, or 4% of the first mortgage amount
- No monthly payment on the assistance
The published statewide borrower income limit is currently $135,750, although program requirements can change. Your lender will verify the current limit, income calculation, credit requirements, and forgiveness terms for your application.
Palmetto Heroes
The 2026 Palmetto Heroes Program offered $10,000 in forgivable assistance to eligible public servants, including teachers, nurses, law enforcement officers, firefighters, EMTs, paramedics, veterans, active-duty service members, and National Guard members.
However, SC Housing lists the 2026 program as closed as of April 13, 2026. The agency says buyers should watch for the 2027 program in spring 2027. If you are a public service professional, it is still worth asking a participating lender whether another SC Housing option may fit your circumstances.
County and Local Programs
SC Housing’s County First Initiative provides additional assistance in selected underserved counties. Charleston County is not included in the current list of targeted counties, so Charleston buyers should not assume this program applies to a property in the Charleston area.
Local grants, nonprofit programs, employer assistance, and municipal initiatives may also become available from time to time. Funding can be limited, and requirements vary. A local mortgage professional can help you check whether a program is active and whether it can be combined with your first mortgage.
How Assistance Works With FHA, VA, USDA, and Conventional Loans
DPA does not replace your first mortgage. Instead, it is usually layered behind it as a second lien or applied as an eligible source of funds.
FHA Loans
FHA financing generally requires a minimum down payment of 3.5% for qualified borrowers. FHA can be useful for first-time buyers and buyers whose credit or debt profile does not fit conventional guidelines.
Assistance may help cover some or all of the required down payment, as well as eligible closing costs. Buyers should compare the total monthly payment, mortgage insurance, interest rate, and assistance repayment terms, not just the amount needed upfront.
If you are comparing FHA lenders in SC, ask whether the lender actively works with SC Housing programs and understands the documentation required for a forgivable second lien.
Conventional Loans
Some conventional programs allow down payments as low as 3% for eligible buyers. Conventional financing may also provide flexible options for borrowers with strong credit, stable income, or lower debt.
Palmetto Home Advantage can pair conventional financing with forgivable assistance. Under program guidelines, some conventional options may also provide reduced mortgage insurance for eligible borrowers.
VA Loans
Eligible veterans, active-duty service members, and surviving spouses may qualify for VA financing with no down payment in many situations. DPA may still be useful for closing costs, prepaid expenses, or other approved charges.
A VA borrower should not assume that a down payment assistance program is automatically better than keeping cash reserves. The right approach depends on the loan terms, funding fee, cash-to-close, and long-term plans.
USDA Loans
USDA loans may offer 0% down financing for eligible borrowers purchasing a qualifying property in an eligible area. Some communities outside the urban core of Charleston may meet USDA property requirements, but eligibility must be checked by address.
When a USDA loan is paired with assistance, DPA may be directed primarily toward closing costs and prepaid items rather than a down payment.
You can review Coastal Funding Corporation’s Charleston loan programs to see how these loan types may apply to different homebuying situations.
Gifts, Grants, Seller Contributions, and Loan Limits
Buyers can sometimes combine several sources of assistance, but the funds must be documented and coordinated correctly.
Gift funds may come from an eligible family member or another approved donor. The lender typically requires a gift letter and documentation showing where the funds came from and how they were transferred.
Grants and DPA may be used for eligible down payment and closing costs, subject to the program’s rules. A forgivable second mortgage is still a lien, even when it does not require monthly payments.
Seller contributions may cover certain closing costs, prepaid expenses, and discount points. Common maximums are approximately 6% for FHA and USDA transactions. VA loans have separate rules for customary closing costs and additional seller concessions. Conventional limits depend on occupancy, loan-to-value ratio, and other factors.
These sources cannot usually exceed your actual eligible costs. If you combine DPA, gift funds, seller credits, and lender credits, your lender will determine how the amounts may be applied.
Assistance also does not increase the applicable loan limit. For 2026, published figures show a one-unit FHA limit of approximately $690,000 in Charleston County and a conforming conventional limit of $832,750. These figures should be confirmed through current HUD, FHFA, and lender sources before you structure an offer.
What Charleston Buyers Should Prepare
A strong application begins before you find the right house. Preparing early gives your lender more time to identify programs and solve documentation questions.
1. Review Your Credit
Ask for a credit review before applying for assistance. Avoid opening new accounts, moving large balances, or closing established accounts without understanding the effect on your mortgage application.
A lower score does not always end the conversation. It may affect the loan type, interest rate, mortgage insurance, or assistance options available to you.
2. Gather Income Documentation
Prepare recent pay stubs, W-2s, tax returns when required, bank statements, benefit letters, and documentation for child support, commission, overtime, or self-employment income.
Single parents and buyers with more than one income source should tell the lender about all consistent, documentable income early. The way income is counted can differ by loan type and assistance program.
3. Complete Homebuyer Education
Many DPA programs require homebuyer education. A course can explain budgeting, inspections, insurance, escrow accounts, maintenance, and the responsibilities attached to a second lien.
Completing education early may help you move more smoothly once you are under contract.
4. Confirm Occupancy and Property Eligibility
Most forgivable assistance programs require the property to be your primary residence. Condos, townhomes, manufactured homes, and single-family homes may be eligible, but property standards vary.
Investment properties and second homes generally do not qualify for first-time buyer DPA programs.
5. Ask for a Full Cash-to-Close Estimate
Do not focus only on the down payment. Ask your mortgage professional to estimate:
- Down payment
- Closing costs
- Prepaid taxes and insurance
- Inspection and appraisal expenses
- Earnest money and due diligence funds
- Seller credits
- DPA amount and repayment terms
- Estimated cash reserves after closing
A Local Conversation Can Make the Difference
Down payment assistance is not one-size-fits-all. The best option depends on your income, credit profile, military or public service status, property location, loan type, and plans for the home.
Coastal Funding Corporation has served South Carolina borrowers since 2004 and works with multiple lenders and loan programs. As you compare mortgage companies in Charleston, SC, look for a team that will explain both the benefits and obligations of each assistance option.

Down payment assistance may make homeownership more manageable, but the right plan begins with clear information, careful preparation, and a lender who stays available throughout the process.
Important Note
Program availability, income limits, loan limits, credit requirements, funding, and forgiveness terms can change. Assistance is subject to program guidelines, lender approval, underwriting, and available funds. Confirm current requirements with an approved lender and the applicable program administrator before relying on any specific option.
