Answer: Since our new blog went live in September, we’ve received a few questions about Cyberhomes’ valuations from our readers.

You can refine your home’s estimate on Cyberhomes with a few easy steps. The Cyberhomes database includes more than 100 million property, ownership, sales and mortgage records, covering more than 85 percent of the U.S. population. Much of our home-value evaluations are based on publicly available facts.It’s likely, however, that you know more about your property than what is publicly known about it. Information about your house that you can supply — such as recent renovations or additions — can modify our estimate of your home’s value.

To get to your home’s property page, click on the “Find My Home” tab at the top of your Cyberhomes page and type in your home address. Clicking on “Change Home Value” will allow you to fix any inaccuracies listed for your property and to note recent home improvements, to possibly impact the estimated value of your home.

To note a home improvement, choose the type of home improvement (e.g., major kitchen remodel or deck addition) from the pull-down menu and add in the completion date and total cost of the project.

Cyberhomes’ valuations are based on a complex process and a variety of data, including those that reflect local housing market trends and economic factors. So in some cases, changes to your home’s facts won’t alter its estimated value.

For instance, the facts about my home on Cyberhomes included the size of the house and the lot, but didn’t include the number of bedrooms and baths or total number of rooms, and incorrectly listed my house as a single-story home.

I refined the facts to note the correct number of bedrooms and baths, number of total rooms and that my house has two stories (we’ve made no major renovations since we’ve owned the home), only to find that doing so didn’t increase (or decrease) the estimated value of my home. Home values in my ZIP code are down just over 10 percent over the past 12 months, according to Cyberhomes. This is not surprising considering the state of the housing market and the economy, but disappointing all the same.—Lauren Baier Kim
