"I recently worked with Dan on a real estate appraisal. After speaking with a few appraisers, I chose Dan because he took the time to thoroughly explain the process, including IRS-qualified appraisal criteria, which made me feel the most comfortable. I was very impressed with his professionalism and expertise. He was punctual, thorough, and delivered a comprehensive report quickly. I highly recommend Dan and would work with him again in the future."

Property Appraiser questions, answered by experts

Yes, the age of your home can impact its value. However, age is just one of many factors that will have an effect. An older home may be perceived as needing more work and maintenance, but if you’ve kept up with repairs or done any renovations, this will increase its value. Buyers will also consider the size of the house, location, and how nearby homes are priced. Lastly, value also depends on whether it’s a buyer or seller’s market.

An FHA appraisal is valid for 180 days from the effective date of the report. In some cases, you can have the appraisal recertified if you make your request before the original expires so that you still may obtain an FHA loan. If approved, your appraisal update is valid for one year.

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). 

While there's not a lot of definite research, some experts suggest that an in-ground or wall-mounted basketball hoop can add value to your home by increasing curb appeal. In addition, having a basketball hoop is an attractive feature of a house since it promotes physical activity, especially for children.

The average cost for a home or property appraisal is about $355, with prices typically ranging from $250 to $500. The final cost is influenced by several factors, including the property's size, age, location, and how it compares to other homes in the area. Appraisals for larger, older, or non-conforming properties often cost more. While a single-family home appraisal usually costs between $300 and $400, appraising a multi-family home can range from $500 to $1,000 due to its increased size and complexity.
