"Very professional, and on-time. I was glad to see that Nancy had a lot of knowledge about different construction techniques and materials. At least in my experience, not every appraiser will be able to recognize and grade the quality of construction the way she did. So, I have consistently found that her appraisals are spot on for what we actually sold the home for. I can definitely recommend her."

Antiques and Jewelry Appraisals questions, answered by experts

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.

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.

While there’s technically no limit to the dollar amount you can borrow for a home addition, the standard limit is around 80% of the value the addition is expected to add to your home. That means you could feasibly borrow up to $80,000 if an appraiser determines that the addition or bump out will add $100,000 in value to your property. You might also be limited by your debt-to-income ratio or credit score.

While a finished basement adds value to your home, it is assigned a different value than space on the main floors. An appraiser will assess the square footage of a finished basement at about 50% to 60% of the value of the square footage for the rest of your home. Appraisal value for a finished basement depends on your location’s real estate market and the specifics of the basement and how it was finished. 

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).
