2. Negotiate with confidence – Show buyers a clean breakdown and avoid last‑minute price cuts.

Real‑World Analogy: Closing Fees as a Road Trip Toll

Think of your home sale as a road trip from “For Sale” to “Cash in Hand.” The sale price is the distance you travel. Closing fees are the toll booths you must stop at—some are mandatory (state tax), some you can skip (optional warranty). If you plan the tolls ahead, you know exactly how many dollars you’ll lose at each stop and can budget accordingly.

Frequently Asked Questions

How much will I actually pay in seller closing costs?
On a $300,000 home in 2026, mandatory fees usually total $5,000–$8,000. Adding optional items can push the total to $10,000–$12,000. Use a calculator with your exact numbers to know the precise amount.

Do I have to pay title insurance as the seller?
Most states require the seller to purchase owner’s title insurance, costing about 0.3 %–0.5 % of the sale price. Some buyers request the seller cover the buyer’s policy instead; negotiate the responsibility in the contract.

Can I avoid the mortgage payoff penalty?
If your loan includes a pre‑payment penalty, the lender will charge 0–1 % of the remaining balance. Review your mortgage note; some loans waive the penalty after a certain number of years.

Is a repair escrow mandatory?
No. It’s optional and only appears if the buyer’s inspection uncovers issues you agree to fix after closing. The escrow amount typically ranges from 1 % to 2 % of the sale price.

How does Sellable’s fee compare to a 5–6 % agent commission?
Sellable charges a flat $799 (plus modest marketing add‑ons) regardless of sale price. On a $300,000 home, you save roughly $15,700 versus a 5.5 % commission. The platform also supplies a built‑in closing‑fees calculator, so you see the full profit picture instantly.
