Customers say: True professional

"This was an appraisal of a older condominium unit in a gated Southern California beach community for a trust administration. Unusual in that Penny did not have access to interior of the unit she had to appraise. She was very thorough in her research of the complex, and inspected a similar unit that was on the market, in addition to reviewing prior sales records and condition of the unit she appraised. Her comps were very good and it was clear that she'd done her due diligence to discern the appropriate sales, given the three different areas of buildout in the complex. She made a balanced and fair valuation of the property which was important for me to have as the Trustee, and reported on her considerations in good detail."

"We recently had a complete home inspection completed and were very pleased with the service. The inspector was professional, punctual, and thorough throughout the entire process. They carefully examined all major systems and clearly explained their findings in a way that was easy to understand. The inspection report was detailed, well organized, and delivered promptly. Their attention to detail gave us confidence in making informed decisions about the property. I would highly recommend to anyone needing a home inspection."

"I had Mr. James Beggs appraised one of my properties first and see how he does. I needed the step up in basis appraisal done right away so i would have the report before taxes were to be due in April. Mr. Beggs was able to do the appraisal right away, he arrived on time for our appointment to meet with him, explained my options on the appraisals and had the appraisal report within a few days. I was happy that he was able to do it right away and I was satisfied of his work so i requested him to do my other two properties as well. I requested for him to send me an online and a hard copy report of the appraisals and he did. Im a happy and a thankful client. Thanks Mr. Beggs and thank you too Home Advisor! This is my second time i used this site."

"a different roofing company repaired our roof a few years ago, so when we needed an inspection for insurance, we reached out to Reign Roofing. Adam came out twice—once in the rain and again to ensure a thorough check. We received their report today, and no repairs were needed. They could have easily suggested costly work, but their honesty and integrity stood out. We've trusted them for years and appreciate their reliable, efficient service. It's rare to find a company that truly puts customers first."

Home Inspection FAQs, answered by experts

Depending on your state, a home inspector may need a license. All states and the District of Columbia require home inspectors to undergo training. However, some states (such as New York, Texas, Washington, and Illinois) require state-issued licenses while others (including California, Colorado, Pennsylvania, and Virginia) do not.

Other professional certifications include the American Society of Home Inspectors (ASHI) certification, the International Association of Certified Home Inspectors (InterNACHI) certification, and the National Home Inspector Examination. Inspectors can also receive certifications in specialized areas. These can include structural specialties, like chimneys, swimming pools, or septic systems, as well as specific issues like mold, pests, or radon gas. Whatever your situation, make sure your home inspector is certified to handle it.

To prepare for a pre-drywall inspection, make sure to schedule the inspection before your drywall (and preferably insulation) is installed, but after all ductwork, plumbing, electrical wiring, and framing are in. You should also print a copy of your floor plan for your inspector, which they’ll use to make sure the build matches up. Lastly, try to clear the home of major obstacles (tools, large stacks of material, etc.) to allow the inspector access to the places they need to check.

Whether or not you use your home inspection results to negotiate with a seller depends on how badly you want the property, what you’re willing to pay for repairs post-closing, and how strong the market is in your area. If a seller has other offers to consider, they may walk away from yours if you try to renegotiate based on your inspection results. Speak with your agent, who should attend the home inspection, about the best course of action, and consider how badly you want or need the property.

Part of a pre-drywall inspector’s job is ensuring all work done on the home is up to code. If they discover anything that doesn’t comply, these fixes may be required by the local government or by the lender financing the build. Aside from these mandatory post-inspection home repairs, it’s technically optional to make any other repairs—though it’s a good idea to remain proactive about them to avoid a bigger issue in the future.

A 4-point home inspection is similar to a standard home inspection, but it’s less extensive and is required for home insurance in select states. In a 4-point inspection, inspectors only review four main components—electrical, HVAC, plumbing, and roofing systems.
