I would tap every source of money I can get.  

Hello BP,I am looking for some advice from other successful Investors, we have a number of properties now under our Belt, all owned Free and clear. We currently have properties in Tennessee, Ohio and Michigan and want...

Consider the source of where it came from and take the writings of some of the premier real estate CPAs such as @Brandon Hall and @Steven Hamilton II to heart.  

So it's more of a trade-off that you'll probably make less but you get to be much more passive (literally you just wire money) vs getting your hands dirty in sourcing, funding, and maintaining 10 SFH.

They are a great source of information and help.For your BRRRR Refinance planning purposes you need to try and keep your all-in costs (Purchase price, Rehab costs, Closing and Holding costs) to no more than 70% of your ARV.  

Anyone source deals at the meetings?

I know when banks loan, having a W-2 income source is a huge factor in lending. 

@Tony Velez, Good way to follow up.. try to source the area and ask tenant in #2 to try and limit smoking times and areas if possible that's causing the problems,, people with asthma and allergies are more sensitive and could get a doctors note saying they can no longer live in unit due to second hand smoke and you'd be hard pressed to hold them to their lease if you can't solve the issue. 

Hubzu - indeed, most auction sites - will not be a good source of profitable properties unless you're buying to owner occupy.

@Jim Brozny thanks Jim as always for being a great source.
