"Excellent Home Appraisal Experience! Review: I recently had the pleasure of working with a fantastic home appraisal service for a home in Diamond Bar, CA. From start to finish, the team was professional, thorough, and provided exceptional service. Being on another coast, choosing an Appraiser was daunting. The final appraisal report was comprehensive and well-documented, providing me with a clear understanding of my home's value. Not only did the appraisal process go smoothly, but the team also demonstrated excellent communication skills. I highly recommend this home appraisal service for anyone in need of a reliable and professional assessment of their property. Their expertise and attention to detail truly set them apart. Thank you to the entire appraisal team for their outstanding service. Kind regards, Brody D"

"Mike Anderson was the consummate professional and was very knowledgeable. We had a great connection and he followed through on getting both estimates completed during the timeline that we agreed to which was in less than a week. I would definitely recommend Accelerated Appraisals to my friends and family. I would just like to suggest paying closer attention to the small but important details prior to emailing the appraisals to the customer."

Property Appraiser FAQs, answered by experts

In most cases, you can expect home automation to boost your home value. This technology makes the homeowner’s life easier and more comfortable, and some provide increased safety and protection. Buyers will likely recognize value in security systems and utility monitors, as well as comfort-focused upgrades that save on electric bills while keeping interior rooms at the desired temperature and humidity. On average, you can expect a 50% and 75% return on investment on home automation services, and potentially even more if the automation reduces homeowner’s insurance.

Appraisals are not mandatory but are helpful for pricing accuracy and negotiation purposes.

Yes, installing a tennis court can be a worthwhile home improvement project that adds value to your property. The potential increase in value can range from $20,000 to $150,000, and in some cases, the return on investment can cover more than 60% of the installation cost. However, the impact on value heavily depends on the size of your property. For homes with multiple acres, a tennis court is often a valuable amenity. In contrast, for homes on smaller lots, installing a court can decrease the property's value because it consumes a significant portion of the usable yard space. It's crucial to consider your property size and the remaining usable yard before proceeding.

In cases where an appraisal comes in lower than an offer price, sellers might opt to lower their asking price to meet the appraisal, especially if the market is slow, and replacing the offer with a higher one may take a long time. Sellers can also offer to make repairs to boost the appraised value, hire another appraiser to get a second opinion, or just move on to another offer that isn’t contingent on the buyer getting a mortgage or an appraisal inspection.

Some appraisers hold a Member of the Appraisal Institute designation. This accolade is the highest credential property appraisers can earn. An MAI appraisal is typically used for commercial properties.

While your lender will likely recommend an appraiser, you can also hire a professional home appraiser on your own. Choose someone who is experienced in your type of residential property, and ensure they hold all of the necessary credentials that your state or region requires.
