How do realtors estimate repair costs?

How do you estimate house repair costs from a report?

Realtors estimate repair costs two ways, and neither is a guess. Send safety findings, and any line whose price could swing by thousands, to a licensed contractor for a written bid. Price the routine lines straight from the report. Then put a number, a scope and a named source on every line your client sends.

The split fits a short window. A bid needs a contractor at the property, which means scheduling around the seller. A report-based estimate needs only the PDF.

Key takeaways

• Don't expect the inspector to price it. The International Association of Certified Home Inspectors (InterNACHI) standards don't require repair cost estimates.
• Forward bids only from licensed, insured contractors, as the Federal Trade Commission (FTC) advises, and check the license first.
• On the sample report below, two routine lines come to $1,037 to $2,426 on national figures, permit included, and the roof leak waits for a roofer's bid.

Can't the inspector or you just give your client a number?

Neither is the right source. The InterNACHI Standards of Practice list what an inspector is not required to determine, and repair or replacement cost estimates are on that list. The report tells you what's wrong, not what it costs.

Before you ballpark a repair yourself, read Article 11 of the National Association of Realtors (NAR) Code of Ethics. It bars Realtors from providing specialized services outside their field of competence unless they bring in someone who is competent or fully disclose the facts to the client. It also requires that anyone brought in be identified to the client. So tell your client who produced every figure.

Which findings go to a specialist first?

Safety findings go to a licensed specialist before the deadline, ahead of any pricing. That means gas, carbon monoxide, sparking or scorched wiring, active leaks and structural movement. Wiring goes to a licensed electrician, and an active leak to the roofer or plumber whose work it is. Ask each specialist for the scope in writing, since that scope becomes the line on the request.

For a gas smell at the property: leave, then call the gas utility's emergency number or 911 from outside, then a licensed professional. The Public Service Commission of Wisconsin puts the first step plainly: "If you smell natural gas leave the area immediately." For suspected carbon monoxide, the Consumer Product Safety Commission (CPSC) says to "get outside to fresh air immediately, and then call 911." A licensed professional finds the source after that.

Send structural findings to a structural engineer, who defines the repair before anyone prices it. The same InterNACHI standards say the inspector is not required to "provide any engineering or architectural service."

How do you price the rest of the report?

Use two routes, each for the lines it suits.

For bids, the FTC says to consider only contractors who are licensed and insured, and to get more than one estimate. A written estimate should include a description of the work, materials, completion date and price. When estimates differ widely, ask why, and don't default to the lowest one. Check the license with the state or county before you forward a bid to your client.

For the routine lines, pick an estimate that shows its parts. Kept prices every line of an inspection report for $79, usually under 4 hours, and flags findings that need a professional's quote instead of pricing them. Each line shows labor, materials, contractor charges and tax, with wages anchored to Bureau of Labor Statistics (BLS) data for the home's metro area (how the prices are built).

What does a priced list look like?

Say your client's report has three lines. The inspector recommends replacing the water heater, one bathroom outlet lacks ground-fault circuit interrupter (GFCI) protection, and there's an active roof leak at a vent.

The permit gets its own line because HomeAdvisor lists it as a separate cost from the unit and install.

The leak waits for a bid. It's active, so it goes to the roofer anyway, and the report can't show what's under the shingles. Today's Homeowner says small leaks around vents typically cost $80 to $120 to fix, but leaks caused by deeper structural issues may require costly repairs, and major structural repairs can reach $15,000 or more. Only the roofer can tell you which one your client has. The request goes out with local figures in place of the national ranges, plus the roofer's number.

What goes on the repair request?

One line per finding, in the report's order. Each line carries the finding in the inspector's words, the report page, the scope of work, the dollar figure and who priced it.

If a bid won't land before the deadline, list that line with its scope and a note that the price will follow the contractor's written bid. Don't fill the gap with a guess. Pricing inspection findings as a buyer's agent covers how to set each figure. The buyer repair request letter template gives the wording.

What if the listing side disputes your numbers?

Ask for their contractor's written bid on the disputed line, with the same parts the FTC lists. Then compare the two line by line. A lower bid that leaves out the permit, disposal or trip charge is not the same job. When a price shows its parts, you can point to the part in question instead of defending a single total.

If the gap won't close, your client chooses: accept the smaller figure, take a credit, or walk away inside the contingency. The contract sets the exact dates and termination terms, so confirm them with your broker or a real estate attorney before your client relies on walking away.

How do you compare realtor repair estimate tools?

Check three things: each line shows its parts, lines it can't price are flagged, and the turnaround beats your deadline. Inspection report repair estimate services compared puts price and turnaround side by side.

Can you use national cost ranges?

For triage, yes. They show which lines are small and which need a bid. They aren't priced to the home's metro, so replace them with local figures before the request goes out.

How do you get a number on every line before the deadline?

Order the bids the day the report arrives. Price the routine lines the same day. The request is then ready when the last bid lands.

If your client's report is sitting unpriced with the deadline this week, upload it to Kept and have the routine lines priced before you draft the request.
