Customers say: True professional

"This was an appraisal of a older condominium unit in a gated Southern California beach community for a trust administration. Unusual in that Penny did not have access to interior of the unit she had to appraise. She was very thorough in her research of the complex, and inspected a similar unit that was on the market, in addition to reviewing prior sales records and condition of the unit she appraised. Her comps were very good and it was clear that she'd done her due diligence to discern the appropriate sales, given the three different areas of buildout in the complex. She made a balanced and fair valuation of the property which was important for me to have as the Trustee, and reported on her considerations in good detail."

"Very friendly, punctual (I will never work with people not on time). He kept his word on the report being done in 5 business days. He contacted me to make sure I received the report, which I appreciate. I'd definitely recommend John and would use him again if I need another appraisal!"

"I needed to have a fair and unbiased appraisal by a certified appraiser to assess property values as of the date of my mother's passing. I spoke with Randy and by the answers he gave to my questions, I determined he was the right professional to engage with. His reports were consistent in methodology, clearly explained in each category, and well accepted by my estate attorney for the exercise. Beyond that, he was professional with his dealings with me and did not hesitate to take the necessary time to ensure I understood the appraisal contents."

Property Appraiser FAQs, answered by experts

Land doesn’t depreciate in the same way that a house, vehicle, or other property does, but it can lose value based on various factors. Environmental changes, nearby development, zoning changes, and economic downturns can all cause land to lose value over time. Value is a comparative figure, so as other related factors change, so can land’s value.

If you can’t find any records online, you’ll need to contact your county clerk’s office to do further research. They should have property records on file, or can at least point you in the right direction of who to contact. You can also speak with your neighbors about when their houses were built because they were likely built around the same time.

A comprehensive smart home system can be really attractive to buyers and increase the value of your property. Components such as a smart security system, smart lawn and garden systems, and smart appliances can all drive up the value of your property.

The purpose of the home appraisal determines which party pays for it. You’re generally responsible for the cost if you need to know the current value of your home to refinance your mortgage, though in some instances the lender will pay for it. The buyer pays for the appraisal when they are applying for their mortgage.

Wainscoting isn’t a design element that can be directly tied to an increased house price. Despite that, it is a highly marketable element that can generate significant interest from potential buyers who enjoy the style, and is relatively inexpensive to remove for those who don’t. If you are on the fence about paneling, just know that it certainly wouldn’t result in depreciation of your home’s value—usually the opposite.
