If your mortgage estimate keeps changing, you are not alone. In Fort Mill, your monthly payment is shaped by more than principal and interest. Local property taxes, insurance, HOA dues, and even your credit profile all play a role. In this guide, you will see what truly drives your payment, how Fort Mill’s millage affects escrow, and two quick scenarios that show the math. Let’s dive in.
The big pieces of your payment
Price, down payment, loan amount
Your loan amount starts with the purchase price minus your down payment. In a market where typical sale prices have been in the upper 400s to low 500s in 2025, the size of your down payment changes the loan amount and whether you need mortgage insurance.
Rate and term
Your interest rate and loan term drive the principal and interest portion of your payment. As a national benchmark, the 30‑year fixed averaged about 6.27% in mid October 2025. Rates move weekly, so always check current readings from the Freddie Mac Primary Mortgage Market Survey when you are shopping.
Mortgage insurance
If you put less than 20% down on a conventional loan, you will likely pay private mortgage insurance (PMI) until you reach enough equity. Some buyers consider a piggyback second loan to reduce or avoid PMI, but this option has its own tradeoffs. Learn how piggybacks work in this PMI alternatives explainer.
Fort Mill property taxes explained
How South Carolina calculates your bill
South Carolina uses an assessment ratio multiplied by a millage rate. The owner‑occupied legal residence ratio is typically 4%. The general formula is:
- Annual tax ≈ Market value × Assessment ratio × (Total mills ÷ 1,000)
Many lenders collect one‑twelfth of your annual tax with your mortgage each month and hold it in escrow.
2025 Fort Mill example
York County’s FY2025 schedule lists Fort Mill’s owner‑occupied levy at 237.2 mills. Using the 4% assessment ratio, that works out to an effective rate of about 0.95% of market value per year. See the county’s official levy table here: York County 2025 Millage Rates PDF.
Example using the formula: If a home’s market value is $488,100, the annual tax would be about $4,631, or roughly $386 per month in escrow. For address‑specific lookups and billing details, use the York County Auditor resources.
Insurance and flood considerations
Lenders require homeowners insurance. Recent state surveys place South Carolina’s average annual premium in the low thousands, often around the mid $2,000s, but your quote can vary based on age of home, roof condition, and claims history. For budgeting, review state averages from Insure.com, then get local quotes early.
If a property is in a FEMA Special Flood Hazard Area or near Lake Wylie or local creeks, your lender will require flood insurance. Here is a clear primer on lender‑required flood insurance.
HOA dues, closing costs, and points
Many Fort Mill communities have HOAs. HOA dues are usually paid directly by you, not through lender escrow, but lenders still count them when qualifying your debt‑to‑income ratio. Ask for the current dues and any pending special assessments.
At closing, you will also decide whether to pay discount points to lower your rate or take lender credits to reduce upfront costs. The Loan Estimate and Closing Disclosure explain fees, escrow setup, and rate options. The CFPB’s guide shows what to look for on these forms: Closing Disclosure explained.
Your borrower profile matters
- Credit score. Higher scores usually earn lower rates, which can save hundreds per month over typical Fort Mill loan sizes.
- Debt‑to‑income (DTI). Lenders qualify you based on your total monthly debts compared to your income. Program rules and product guidelines vary, and the GSEs buy only qualified mortgages under current policy. See FHFA’s update on QM limits: FHFA qualified mortgage guidance.

What to do next
- Pull the current county millage and verify whether the home is owner‑occupied at 4%. Start here: York County Auditor resources.
- Get quotes from at least two lenders and compare the Loan Estimate line by line for rate, points, and PMI. Review the CFPB guide.
- Request homeowners insurance quotes early. If the home is near water or mapped flood zones, ask about flood requirements.
- Ask the HOA for current dues and any planned assessments so you can budget accurately.
- Plan for escrow changes. If taxes or insurance rise, your servicer may adjust your monthly escrow. Here is a simple overview of how escrow balances work.
- Keep an eye on local budget actions. School and local levies can affect mills. For example, the Fort Mill school board discussed a potential millage change in April 2025, as reported by WRHI.

FAQs
How do I estimate Fort Mill property tax on a specific home?
- Use Market value × 4% assessment × (total mills ÷ 1,000). For the current levy, check the York County millage schedule and the Auditor’s page for tools and billing details.
Can I avoid PMI with less than 20% down in Fort Mill?
- Sometimes with a piggyback second loan or specific programs, but each option has tradeoffs in rate, fees, and risk. Compare total cost using this PMI alternatives explainer.
Are Fort Mill mortgage rates different from national averages?
- Your final rate comes from your lender and profile, but national benchmarks like Freddie Mac’s PMMS are useful for tracking weekly trends.
Do HOAs get included in my mortgage escrow?
- Typically no. HOAs are paid directly by you, though lenders count dues in your debt‑to‑income ratio when approving the loan.
Will school millage changes raise my monthly payment?
- Owner‑occupied homes receive an operating exemption, but other school and local levies can still affect total mills. If mills rise, your escrow can go up. See local reporting like WRHI’s April 2025 update and confirm with the county.
