If no one is a renter, or very few, then it's probably not a solid rental area.What class properties are you purchasing? 

Yes, if somehow you keep getting tenants who want to break your lease and you keep giving breaks to a protected class, that might be a problem. 

Hi All,I am currently looking at a potential deal in an solid C class neighborhood here in Miami.The building is a 4 plex that suffered fire damage and was completely gutted.

I avoid large old houses in once-prosperous, now C-class areas that were converted at some point into makeshift duplexes and triplexes.

There’s a few other well known classes around that will work based off of you schedule. - Steve  

Jonathan, thank you for the reply.5 - 20  door commercial properties is the type of mf  I will concentrate on ( b and c class). 

You do need to be careful these days about what's said in the letter, and leave HUD's protected classes out of it.

Hi @Kyle Knowles  NJ is mainly online for real estate classes right now. 

Provide a written report of income/expenses for the month.If you intend to manage for others, you my consider joining a professional organization like NARPM where you can take classes and accelerate your learning.

All you can do is make smart moves and buy cash flowing assets in working class areas.
