Frequently asked questions

Are these numbers exact?+

No. They are estimates built from public-record averages: median home price (Zillow ZHVI), effective property-tax rate (Tax Foundation), state-level homeowners-insurance averages. Your final Loan Estimate and Closing Disclosure are the authoritative figures.

Why does the same loan amount cost so much more here than in other states?+

Two big drivers: state and county taxes (transfer, recording, intangible) and homeowners-insurance pricing. Florida and Texas pay heavier insurance. New Jersey and Illinois pay heavier property taxes. Nevada and Washington layer on real-estate excise taxes. The calculator shows each line item so you can see where the money goes.

Who pays which costs at closing?+

Most line items are negotiable but follow strong local custom. In Florida, the seller pays doc stamps on the deed and the owner's title policy. The buyer pays doc stamps on the note plus intangible tax. In California, the seller pays the owner's title policy in Northern CA but the buyer pays it in Southern CA. In Texas, the seller customarily pays the owner's title policy. Always confirm with your title officer.

All numbers shown are estimates for planning purposes. Closing costs, taxes, and fees vary by lender, title company, county, and individual transaction. LoanElk is not a lender, broker, or financial advisor. Your final Loan Estimate and Closing Disclosure are the authoritative figures.
