I have used her service numerous times to have my assessment appealed on my house. The tax saved for 3 years of the assessment cycle with the second installment of my 2014 real estate tax bill is $2557.59. They are very professional and would recommend them to reduce your taxes. My brother who owns two apartment buildings also has used their services. Angie's List had a $50.00 coupon off of their services which reduced my fee to $291.04.

Property Appraiser FAQs, answered by experts

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

Around 1-2 weeks, including inspection and reporting time for an official evaluation.

In most cases, installing a tennis court on your property will drive up your property taxes. Property taxes are determined, in part, based on improvements made to your property, which includes anything with a permanent foundation. Since most home tennis courts include a large concrete foundation, your property taxes will likely increase following the installation. A general rule of thumb is that if your project requires permits—like for a foundation or fencing for a tennis court—then your property taxes will be affected.

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.

Whether a scullery is worth it depends on how much you like to cook and entertain. If you frequently host gatherings—a scullery is likely worth the money. If you’re looking for ROI, it’s not so clear. It may not add significant value to your home, as it doesn’t increase square footage and may repurpose space that a buyer would have preferred to remain as-is (like a laundry room).
