Short answerIt depends on the house and how prepared you are. Small requests for safety items may run a few hundred dollars. Requests involving a roof, furnace, panel, sewer line, or basement water can reach thousands. The best protection is knowing those items before you list, so price and terms already account for them.

How do I protect my net?
- Fix cheap safety items before listing. What to fix before listing.
- Get quotes on big aging systems before you list, so you can answer with real numbers.
- Disclose known issues up front so they are priced into offers instead of renegotiated later.
- Answer requests with options: repair some, credit others. Repair, credit, or price reduction.
Frequently asked questions
Do I have to agree to repairs?
No. A repair request is a negotiation under your purchase agreement.
Can I get quotes before the buyer's inspection?
Yes, and it helps. A condition walk can point to what is worth quoting.

Want to know what a buyer's inspector may find before they do?
Book a free pre listing condition walk. I walk the house with you, point out what inspectors and FHA, VA, and USDA appraisers tend to flag, and give you planning ranges so you can decide what to fix, credit, price in, or disclose.
Book a condition walkOr call or text (812) 525-5489, or email john@yourpropertynegotiator.com.
The condition walk is a REALTOR® and contractor evaluation, not a home inspection, and it does not replace one. If you have already signed a listing agreement with another agent, please take these questions to your agent.
