How do you find the equity?

[Ashley Swift]

I'm just getting started out and would like to know how do I find the balance a home owner owes on their mortgage?

[Thomas Weir]

The easiest way would be to ask the potential seller when they call you in response to your marketing. There are paid sites out there like Realty Trac that can give that information, but as Ned C stated it's probably an estimate based on how long the seller lived in the property.
