@Chris Seveney While I'm not at that level to be able to provide personal experience I will follow to see what others respond with.One question I would have is, 'What is your current loan volume today?'   

If you follow up, please share what you learn here.

(And I would tell you to not buy a property that doesn't cash flow unless you have significant resources behind you that could absorb anything that could come at you - like replacing a $5,000 AC one month followed by replacing a $1,000 hot water heater the next).   

What I do gain is being able to place tenants much faster than my competitors who simply follow a mold. 

The systems you have in place to handle leads, follow-up and your sales processes are also huge factors.Another factor is what is your monthly marketing budget?

Real Estate has a lot of niche's one can follow thats what makes it exciting.

Lead paint testing requires no supervision or follow-up inspection.

Just be sure it’s documented and consistently applied to avoid any Fair Housing pitfalls.Another option is to stick with strictly quantifiable criteria—credit score, income ratio, etc.

Buying in your backyard eliminates so much for you.What strategy do want to follow?   

It will depend on where you are doing your deals and what the liability is that follows you after a sale.
