Best Online Home Appraisal Tools (2024)

Go Back To Previous Page

Online home appraisals can give homeowners and buyers a basic understanding of a property’s value. However, it is advisable to engage a professional appraiser for more precise and legally recognized appraisals, particularly when financing or selling. Let’s review the Top Online Home Appraisal Tools for 2024.

Many people, whether they’re thinking about selling their property, refinancing their mortgage, or simply curious about their investment’s current market value, often ask, “What is my home worth today?” Free online home value estimators can provide you with an estimate of what your house might sell for or how much equity you’ve accumulated so far.

Many lenders and real estate companies offer an automated valuation model (AVM) on their websites, where you can enter your address to receive an estimate.

However, these tools should not be considered substitutes for a formal appraisal or the in-person expertise of a real estate agent; they serve as a helpful starting point.

Most of these estimators combine various sources, including county auditor and property tax assessor records, user-submitted data, and multiple listing service (MLS) listings and sales, to generate their estimates.

What Is an Online House Appraisal?

An online house appraisal estimates a property’s value using online tools and databases. These tools use recent sales of comparable homes, current marketBest Online Home Appraisal Tools trends, and property details to estimate a home’s value.

If you’re wondering which online home value estimator is the most reliable and accurate, it’s essential to consider several key factors. Key data points used to calculate a home’s value include its square footage, acreage, number of bedrooms and bathrooms, and the year it was built. However, each tool may have limitations, such as gaps in data or coverage restricted to specific market areas.

While they offer convenience and quick results, they may not be as accurate as a professional appraisal conducted by a licensed appraiser. These online tools are also known as home value estimators. (HVA)

How Do Online Home Appraisals Work?

Online home appraisals use an algorithm called Automated Valuation Modeling (AVM) to estimate the value of your house. The algorithm considers the information you provide, the house’s sale history, and the sale prices of homes nearby.

However, the accuracy of the residential appraisal depends on the available data, meaning that online appraisals may not be as accurate as traditional ones, as they may not easily account for factors such as new renovations and variations in the quality of finishes between homes.

The convenience of online home appraisals means real estate professionals can obtain them for free with minimal effort, making them appealing to those who are short on time and cash.

How to Get a Home Appraisal Online

To receive an online home appraisal, visit a website that offers online appraisals, such as Ownerly, and request an appraisal. You’ll need to provide details about the house you want appraised. After that, they will give you an approximate estimate of the property’s value based on similar homes in your area.

It’s a straightforward process, but note that online home appraisals provide only a rough estimate of your home’s value. Even the most accurate estimators can typically only be within 4-6% of a property’s actual value.

How Accurate Are Online Home Appraisals?

Remember that online home appraisals can provide a general idea of your home’s value, but they are rarely entirely accurate.

Online appraisals often overlook several key factors, including damage to your home, updates, renovations, and the historical value of your property. For example, they may not be able to detect issues such as leaky pipes or wall damage, which can significantly reduce your home’s value.

Additionally, the appraisal may not reflect updated features, such as remodeled bathrooms. Furthermore, if your home holds historical significance and is not accounted for in the online appraisal, you might receive an underestimated value.

We recommend you obtain multiple appraisals from different websites to minimize the risk of receiving a low estimate.

What’s the Most Accurate Online Home Appraisal Tool?

Finding the most accurate online home appraisal tool can be challenging, as new providers frequently introduce new tools and improve their technology. However, the real estate giant Zillow owns one of the market’s most notoriously inaccurate home valuation tools.

Their Zestimate appraisal is well known for its inaccuracy despite their claim of always being within 4.5 percent of a home’s actual value. Some high-profile examples include former Zillow CEO Spencer Rascoff listing and selling his homes at more than 30% off the Zestimate appraisal.

Why Do Online Home Appraisals Vary?

If you obtain a home appraisal online, you may receive different estimates from various sources. This can happen because each site uses multiple data sources and algorithms.

Therefore, it’s important to remember that these estimates are rough approximations and may not be reliable.

Can a Free Online House Appraisal Replace a Standard Appraisal?

Free online house appraisals can give you a general idea of your home’s value, but they may not be as reliable as in-person appraisals because they don’t account for all the damages and upgrades.

If you’re serious about buying a specific house and are seeking bank funding, an in-person appraisal is necessary.

Lenders require an official appraisal before finalizing the purchase. A free online appraisal is sufficient for general curiosity about your home’s value. Just remember not to base significant decisions solely on an algorithm.

Online Home Appraisal Bottom Line

Online house appraisals are becoming increasingly accurate and popular. They can provide a general idea of your house’s current value, but are not recommended for severe homebuyers, as most lenders won’t accept them for buyer’s appraisals.

If you’re serious about buying a house, hiring a local appraiser is best to get an accurate valuation. While online home appraisals are convenient, hiring a live person can save you time and money in the long run, ensuring you get the best price for your home.
