Vacancy and Rent Rates

[Shulem Elias]

hi 

while I'm looking through many "multifamily" deals, though to be honest I don't see that there are too many of those,

one of the things that I'm looking for is the average rent and vacancy %  in the area that I'm looking into ?

I did it  through checking other rentals or trying to reach locals (not easy at all)

is there an official website or so where I can find constant up to date information?

please let me know 

thanks to all
