Customers say: Quality work

"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

The cost ranges from $300 to $500, depending on the property's size and location. Due to their complexity, commercial appraisals may cost more.

The condition and appearance of your yard can affect your home appraisal value. A well-maintained, attractive yard with curb appeal adds to a property’s value, while an overgrown, messy, poorly maintained yard can hurt your home’s appraisal. Even small cosmetic improvements to your yard, like adding mulch, trimming trees, and cleaning out plant beds, can help your appraisal value.

The entire appraisal process takes from seven to 10 days. This timeline accounts for the many steps of the appraisal process, including the post-inspection report completed by the appraiser.

Home appraisal services include the following tasks:

  • Inspect home interior and exterior

  • Evaluate materials, features, fixtures, and renovations

  • Review comparable properties

  • Write an appraisal report

Installing a flagpole can improve your home’s curb appeal, so it will often have a modest positive impact on your property value. You’ll see a much larger bump in property value if you install a custom wooden flagpole than you would if you install a standard aluminum pole. Adding lighting to your flagpole will also have a positive impact on home value, as will trimming trees away from the new lawn addition.

Basement bedrooms can count toward your room count and the square footage of your home on an appraisal if they’re fully legal, which means they have proper ventilation and points of egress, as defined by your local building code. Simply partitioning off a space for a bedroom in an otherwise unfinished basement that isn’t a legal living space won’t affect your appraisal value.
