What is the best way to know about price history of a property?

[Giridhara Gowdra chandranna]

Are there any websites which keep track of the price history of the retail housing properties

? Redfin gives some info on this, but not all the properties have this. But if I have a off market property(not on MLS) and want to know the price history what is the best source?

Texas is a non-disclosure state, so if the property was exchanged privately, there is likely no way to know the true sale price.  You might get a rough idea from a note if you find one attached to the property, but you'd have to read through it in detail to maybe decipher any holdbacks or down payments.
