TopConnector: The Largest Property Database - As Mobile As You Are!



About TopConnector App

TopConnector app provides instant access to data on over 110 Million U.S. properties and their owners, in all 50 states, updated weekly. All in one place - your hand.

Whether you are in real estate, insurance, home repair/renovation or any other business offering services to property owners, you will love the easy access to property data.

TopConnector is powerful yet incredibly simple. It takes just a few seconds to get data on any U.S. property – residential or commercial - just by touching the property on the map. It's such a cool way to lookup the info you need, whenever you need it! You'll get the property value, size, age, characteristics, tax, mortgage, last sale, how many years since the last sale, and more. You'll find out who is the property owner, their contact info, absentee status, how long they have been living there, key owner demographics. If it's a business, you'll find out who is the business owner, key executive, contact person, phone, key sales figures, and more.

Getting property and owner data doesn't have to mean breaking the bank. When you subscribe to the service, you will get unlimited access to all of the property and owner data, nationwide. You'll pay per month, not per record. No account is required, no membership. You won't find a better deal anywhere else!
