What is a jumbo loan in South Carolina? 2026 jumbo mortgage limits and requirements

Living in South Carolina offers a mix of coastal charm, historic cities, and fast-growing communities – and in many parts of the state, home prices are increasingly pushing above national norms. Continued growth in areas like the Charleston metro, Mount Pleasant, and Sullivan’s Island has more buyers relying on jumbo loans, which are mortgages that exceed standard conforming loan limits.

Below, we’ll break down what a jumbo loan is, the current jumbo loan limits and requirements in South Carolina, and how to decide whether this type of financing makes sense as you explore buying a home in the Palmetto State.

What is a jumbo loan in South Carolina?

In South Carolina, a mortgage is considered a jumbo loan when the amount borrowed goes beyond the annual loan limits established by the Federal Housing Finance Agency (FHFA). Those benchmarks define the largest loans Fannie Mae and Freddie Mac are willing to buy or back. Once a loan exceeds that threshold, it falls outside the conforming category and must be financed as a jumbo loan.

Jumbo loans exist because housing markets don’t grow evenly. In areas with strong demand, limited inventory, or desirable amenities, home prices can quickly exceed federal lending limits. In South Carolina, this is increasingly common in coastal communities, Charleston-area suburbs, and other low-inventory neighborhoods where even mid-range homes may surpass conforming thresholds.

Buyers who use jumbo loans in South Carolina often include high-income or dual-income households, self-employed professionals, investors, and eligible military borrowers using VA jumbo loans. While often associated with luxury homes, jumbo financing is frequently used simply to remain competitive.

Jumbo loans function similarly to conventional mortgages, but because they aren’t backed by Fannie Mae or Freddie Mac, lenders assume more risk. As a result, borrowers typically face stricter underwriting and qualification standards. That said, today’s jumbo loans South Carolina buyers have access to are often more flexible than many people expect.

Jumbo loan limit in South Carolina (2026)

The Federal Housing Finance Agency reviews and updates conforming loan limits annually to keep pace with shifts in nationwide home values. For 2026, South Carolina does not include any FHFA-designated high-cost areas, meaning every county in the state follows the national baseline limits.

For a single-unit home, the maximum conforming loan amount in South Carolina is $832,750. Borrowing above this limit places the loan in jumbo territory, making it ineligible for purchase or guarantee by federal agencies.

Higher limits apply for multi-unit properties:

• Two-unit property: $1,066,250
• Three-unit property: $1,288,800
• Four-unit property: $1,601,750

While these limits apply statewide, local market conditions are pushing more buyers into jumbo territory. Coastal and metro-adjacent communities continue to see price growth driven by limited inventory and strong buyer demand. Sullivan’s Island, for example, consistently posts median home prices well above $2 million, making jumbo financing a necessity rather than a luxury. While in Mount Pleasant, steady population growth and proximity to Charleston have pushed median prices upward, with many homes crossing the conforming loan threshold.

Beyond the coast, areas like Charleston County and Berkeley County have experienced sustained appreciation as buyers seek space, amenities, and access to employment hubs. As prices rise across multiple tiers, jumbo loans in South Carolina are becoming a common tool for buyers who aren’t necessarily shopping at the very top of the market.

Requirements for a jumbo loan

Because jumbo loans aren’t backed by government-sponsored enterprises, lenders apply stricter approval standards to manage risk. While requirements vary by lender, most jumbo loans South Carolina buyers encounter share common qualification guidelines.

Property type

Jumbo financing is available for a broad variety of homes, including primary residences, vacation properties, investment homes, and properties with up to four units. This range is particularly valuable in South Carolina, where buyers often consider coastal second homes and unique mixed-use residences in select markets.

Credit score

A solid credit profile plays a key role in qualifying for a jumbo loan. Many lenders look for credit scores in the upper 600s as a starting point, while scores of 720 or higher typically unlock more favorable jumbo mortgage rates. 

Down payment

• Jumbo loans typically require a higher upfront investment than conforming mortgages.
• Most buyers should plan for a down payment between 10% and 20%, depending on loan size, property type, and overall financial strength.
• Larger loan amounts may increase down payment expectations, while VA jumbo loans may allow low or no down payment for eligible military borrowers.

Debt-to-income ratio (DTI)

Most lenders prefer a DTI ratio of 43% or lower, though stricter limits may apply for higher balances. Keeping monthly obligations manageable is especially important when qualifying for jumbo financing.

Steady income

Borrowers must demonstrate consistent, verifiable income. This typically includes: 

• Two years of W-2s or tax returns
• Documentation of bonuses or commissions
• Additional income verification for self-employed applicants 

VA jumbo loans may also incorporate residual income requirements as part of the approval process.

Cash reserves

Expect to show 6 to 12 months of mortgage payments in liquid reserves, and sometimes more for very large loans. These reserves provide reassurance that you can maintain payments during unexpected financial changes.

For buyers who meet these criteria, specialized programs can offer added flexibility. Rocket Mortgage offers jumbo loans through its Jumbo Smart loan program, which allows eligible borrowers to finance loan amounts up to $3 million, helping South Carolina buyers navigate higher-priced markets with peace-of-mind.

Pros and cons of buying a home in South Carolina with a jumbo loan

Jumbo loans can unlock opportunities in competitive markets, but they come with important considerations. Understanding both the advantages and tradeoffs can help you decide whether this financing approach aligns with your goals.

Pros

• Competitive rate potential: Although jumbo loans once carried a noticeable rate premium, that gap has narrowed significantly. Many well-qualified borrowers now find jumbo mortgage rates that closely align with – and in some cases undercut – conforming loan pricing, making this option more attractive than expected.
• No PMI on many programs: A key benefit of jumbo financing is that private mortgage insurance is often not required, even when the down payment is less than 20%. Removing PMI can meaningfully lower monthly payments and enhance long-term affordability.
• Broad loan flexibility: Jumbo loans are available in a range of structures, including fixed-rate and adjustable-rate options, and can be used for primary homes, vacation properties, or investment real estate. This versatility allows buyers to match their loan structure with both lifestyle needs and future goals.

Cons

• Stricter approval criteria: Because lenders assume more risk with larger loan amounts, jumbo loans typically come with tighter credit standards, lower allowable debt-to-income ratios, and more thorough income and asset verification. Borrowers should expect a more detailed review process.
• Greater cash required upfront: Jumbo financing often requires a larger down payment at closing, which can place additional demands on savings. Careful planning is essential to ensure sufficient liquidity without overextending finances.
• Higher reserve requirements: Lenders frequently expect borrowers to maintain several months of mortgage payments in accessible reserves. While these funds provide a safety net, they can temporarily limit flexibility for other financial goals or investments.

Is a jumbo loan right for me?

Choosing jumbo financing is about more than just qualifying – it’s about comfort, planning, and long-term sustainability. Before moving forward, consider the following factors:

• Interest rates: Even small differences in jumbo loan rates can significantly impact payments over time.
• Closing costs: Jumbo loans often carry higher closing costs due to loan size and underwriting complexity.
• Tax implications: Mortgage interest deduction limits may affect higher-balance loans.
• Lender specifics: Requirements and available products – fixed-rate, ARMs, or interest-only options – vary by lender.
• Personal comfort: Consider how comfortable you feel managing a larger monthly obligation over time.

As you consider whether a jumbo loan fits into your overall home-buying strategy, taking a look at today’s mortgage rates in South Carolina can offer valuable perspective on what your monthly payment could be over time.
