Tips for Using Zillow Zestimates

When researching, it’s important to use this tool as a starting point. It is rarely an all-encompassing measure of a property’s value. Consider it alongside other resources and seek professional guidance for a better understanding of a home’s value.

Influencing a Zestimate

Property owners can boost their home’s value and increase their Zestimate price. A sustainable and healthy market can boost a home’s value by about 3-4% yearly, meaning your property could be worth more than last year.

Home improvements also help increase a property’s value. With some simple updating of your home’s siding, roof, deck, carpet, and more, you can increase your home’s worth.

Of course, your home’s value mainly depends on buyer demand. Like in any market, your value will increase if the demand is higher than usual. If the demand isn’t there, even with those improvements, it will decrease.

Seeking Professional Advice

A Zillow Zestimate is designed to give users an idea of a home’s worth. However, it’s not an official appraisal. An appraisal is a professional’s opinion and is always required when a mortgage is involved.

While an appraisal is costly, it is almost always more accurate and comprehensive. If you are selling your property, a professional’s opinion is a great way to decide how much to put it on the market for.

Agents and Appraisers

Consulting with real estate professionals (such as agents and appraisers) is a safe way to consider your options when making a big decision. Their expertise and insights can offer a more comprehensive understanding of a property’s value.

Real estate agents will likely provide context beyond what Zillow Zestimates offers. Their local market knowledge, understanding of property nuances, and negotiation experience can significantly benefit both buyers and sellers.

Zillow Zestimates have undoubtedly changed how people approach real estate transactions, constantly providing valuable insights and accessibility.
