Finding Deals : Below FMV Properties

[Vin Joy]

Greetings!

Wondering is there a way to find homes that are listed for sale (regular, shortsale, make me move) that are below FMV (preferred) or zestimate or other such measure by a specified %?

It will be great if one can specify additional search criteria like year of construction, type, price, zip etc.,

I am sure there has to be a better way of doing this which many of more savvy investors may be using.

Thank you in advance for your guidance!
