Final Verdict

Appraising your belongings online can feel like a scam, but there are many legitimate businesses that can get you real-world valuations to help you understand what your property is worth. If you are looking for a simple price valuation to see what your items will sell for, using a free appraisal service will help you get a relatively accurate market price. Services like Zillow (for real estate) and WorthPoint (for collectibles) use real-world selling price data to show you what you can expect from selling your personal property.

If you need a formal appraisal for insurance or tax purposes, working with a bespoke auction house service, such as Sotheby’s, Bonhams, or Christie’s, will give you a more detailed report from an industry expert, which is valid in a court of law. We chose Heritage Auctions as our top pick for its extensive offerings of free and paid expert online appraisals.

Online Appraisal Services vs. Desktop Appraisal

While both online appraisals and desktop appraisals can refer to getting an appraisal without a physical inspection of your items, desktop appraisals are more commonly referred to as real estate appraisals.

Online appraisal services typically refer to free or paid appraisals for items such as art, antiques, currency, or other collectibles. These services help individuals find the value of their belongings, and can help with insurance and tax purposes as well.

A “desktop appraisal” refers to a home or property appraisal that occurs at the "desk" of the appraiser based on home details, photos, and tax records. Most real estate transactions require the appraisal of a property or home, which usually means a physical inspection from a professional appraiser. But in some cases, a desktop appraisal will suffice.

Frequently Asked Questions

Are Online Appraisal Services Expensive?

Most online appraisal services are not expensive, but some can be. In fact, many of them are free when being used for auction estimates, but formal appraisals can get very expensive, with some billed by the hour or at a daily rate.

Can I Receive an Instant Quote Using Online Appraisal Services?

Some services provide instant pricing estimates, such as Zillow (for homes) and WorthPoint (for valuables). These estimates are basic valuations for selling the item and cannot be used for insurance or tax purposes. Most appraisals will take at least 48 hours or more for an official, written appraisal.

Do Online Appraisal Services Use Experts to Conduct Valuations?

Quality online appraisal services will have on-staff certified gemologists, antique appraisers, auction house experts, and other industry experts to review your valuables. Other online services don’t employ the experts, but rather, consult with them to get their direct valuation for your items.

Can I Obtain a Certificate for Insurance Purposes Using Online Appraisal Services?

Many online appraisals provide a PDF valuation certificate that contains a “replacement value” that can be used by insurance companies to insure your items. That said, most of the free appraisal services do not provide certificates of valuation and are simply for re-selling or auction estimate purposes.
