Take stock of your current credit score and accounts.

i work full time too, so i can only do one big project at a time, and can only make about 1 offer every 1-2 months.my stock answer to anyone is to invest where they live - and for expensive metros that includes 1-2 hours out. 

That is just not realistic in this current market.So in my opinion it's important to expose yourself to a large number of deals, so you can develop an intuitive sense of what's reasonable and what's not (and quickly discard the ones that aren't).And it's true that there is no way to 100% protect from fraud (and not just in passive real estate investments but even in public stocks etc.).

One size does not fit all and I wouldn't take much stock in any advice stating that housing assistance tenants are better or worse as a whole. 

Like any city, there is dilapidated housing stock in rough areas that can cost more to upgrade than they are worth. 

but some parts of the country there is lots of old stock that can be recycled.I mean you could go into Gary indiana right now and buy 100 homes straight away.. 

These areas have affordable entry points, diverse housing stock, and steady demand.

I just did the math and it was obviously better than stock account retirement.

Just like bonds & stocks, different properties will have higher & lower risks.

I've looked into roof stock as a possible option but I've heard nothing but negative reviews about them.
