How to beat a controlled market?

[Royal Bel]

Hello brothers and sisters, I am a new real estate investor and I am excited to be taught by you guys.
I am from a pretty country with pretty f*ck up government ( sorry for the language, but it's true ) and real estate is a mess, it keep going up and down with no direction at all and the bank is no more than robber in day light with their we-do-what-we-want interest rate ( changing over time by their will )  and secret policy about true market value of property, growth rates ( maybe they really don't know ).
So, in short, what will you guys do to find out about the true market price and what kind of leverage will you use if you are in my situation?
I am waiting for your help.
Thanks everyone.
