How to know and get real information about a particular estate 

Appreciation is an important fact to consider when you're trying to determine whether a home is an investment. If the appreciation rate is high enough, then the added value you'll earn from the home will make the investment worth it within a certain period of time.

You can ask the owner of the property who wishes to sell it for documents regarding the property like the sales deed, and get the information verified by a lawyer specializing in real estate transactions.
