Every partnership has these two aspects in a vast variety of combinations as to what each partner will contribute.  

I'd be surprised if your vacancy and maintenance combined are only 10% for the long haul.

In my experience a partnership can be an excellent way to combine complementary strengths in order to realize a shared vision. 

Doesn't anyone throw the ex's crap out on the front yard anymore?

I'm on 15yd dumpster #2 and still have more crap to clear out ... 

Four of them I've had minimum repairs and one of them I've spent more than all the others combined.

the pros use heads that expand to the pipe diameter and really clean the crap put of it...  

I use a combination of my money and private money right now.

Combined cash flow pay the 3 single families off pretty fast.

And owner occupants, for rent to own, who did NOT pass prequalification that you can qualify in the next 12-36 months, have a strong combined household income, and are looking to purchase in the $150k+ range.
