Key takeaways

Conventional loans usually require a minimum 3% down payment for qualified buyers.
Private mortgage insurance (PMI) is typically required if the down payment is less than 20%.
Conforming loan limits in South Carolina follow the federal limits (e.g., $726,200 in most counties).
State first‑time‑buyer programs can be paired with conventional loans for down‑payment assistance.
Most South Carolina closings involve a real‑estate attorney, which can affect costs and timing.

Conventional vs. Government-Backed Loan Options

What buyers in South Carolina actually weigh is a conventional loan against FHA, VA, or USDA financing. Here is how the four main programs differ at a national level — your lender will verify the exact numbers for your South Carolina situation.

Conventional: best for buyers with a credit score of 620+ and at least 3% down; private mortgage insurance (PMI) drops off automatically once your balance reaches 78% of the original value.
FHA: allows credit scores as low as 500–580 with a 3.5% down payment, but charges an upfront and annual mortgage insurance premium (MIP) that typically lasts the life of the loan on 30-year terms.
VA: offers $0 down and no monthly PMI for eligible veterans and service members, in exchange for a one-time funding fee (often waived for disabled veterans).
USDA: offers $0 down for eligible buyers in designated rural areas of South Carolina, with low mortgage insurance and county income limits.

Your ideal choice depends on your credit tier, down payment savings, and whether you qualify for VA or USDA programs. Run the numbers below with our calculator to see how each program shapes your real monthly payment.

Conventional loans are the most common type of mortgage used by homebuyers across the United States, including South Carolina. They are not insured or guaranteed by the federal government, which gives lenders more flexibility but also stricter qualification standards.

What Is a Conventional Loan?

A conventional loan is a private‑mortgage loan that conforms to the underwriting guidelines of Fannie Fi and Freddie Mac. It can be either a conforming loan (within the loan‑size limits set by the Federal Housing Finance Agency) or a non‑conforming "jumbo" loan that exceeds those limits.

Down‑Payment and Mortgage Insurance

Qualified borrowers can put down as little as 3% of the purchase price.
If the down payment is under 20%, lenders usually require private mortgage insurance (PMI) to protect against default.
PMI can be cancelled once the loan balance reaches 78% of the original value, assuming good payment history.

Loan‑Amount Limits in South Carolina

South Carolina follows the federal conforming loan limits, which are updated annually. In most counties the limit is $726,200, while higher‑cost areas may have a higher ceiling. Jumbo loans are available for purchases that exceed these limits, but they often have stricter credit and income requirements.

State‑Specific Considerations

South Carolina offers first‑time‑buyer programs, such as the SC Housing Homeownership Mortgage Program, that can provide down‑payment assistance when paired with a conventional loan.
Closings in South Carolina are frequently handled by a real‑estate attorney rather than a title company, which can affect closing costs and the timeline for document preparation.
Property tax rates vary by county, and some local jurisdictions provide homestead exemptions that can lower annual taxes for primary residences.

Choosing the Right Option

When deciding if a conventional loan fits your needs, evaluate your down‑payment amount, credit profile, and whether you qualify for any state assistance. If you can reach a 20% down payment, you’ll avoid PMI and may secure more favorable loan terms. Otherwise, explore the available South Carolina programs that can help bridge the gap.

FAQ

Can I use a conventional loan if I have significant student loan debt?

Yes, you can qualify for a conventional loan with student loan debt, but lenders will look at your debt‑to‑income (DTI) ratio. Keeping your total DTI below the lender’s threshold (often around 45%) improves your chances.

How does a conventional loan differ from an FHA loan in South Carolina?

A conventional loan is not government‑insured, so it usually requires a higher credit score and a larger down payment than an FHA loan. FHA loans allow down payments as low as 3.5% and are more forgiving of lower credit scores, but they require mortgage insurance premiums for the life of the loan.

What credit score do I need for a conventional loan?

Most lenders look for a credit score of at least 620 for a conventional loan, though a score of 700 or higher typically qualifies you for better interest rates and lower PMI costs.

Are there any South Carolina‑specific fees I should expect at closing?

In South Carolina, you may encounter attorney fees for the closing, as many transactions are handled by a real‑estate attorney. Additionally, there are state recording fees, transfer taxes, and possibly local jurisdictional fees.

Can I refinance a conventional loan later?

Yes, you can refinance a conventional loan to a lower rate, a shorter term, or to cash out equity, provided you meet the lender’s current qualification criteria.
