What things are we missing? 

Hopefully I did not miss anything and this was somewhat helpful.

Seems like there is something I am missing if the rent payments for these properties are less than 1% of the purchase price. 

What happens if they agree to the "deep clean" but the people they hire miss some spots? 

Only 3.4% cash on cash returnI would not, but maybe there is something I am missing

Should something happen even out of your control the "What if factor" and you miss any payment on any debt on credit. 

I'm missing out on over $1k per month by not turning the units over, and the property is not an attractive investment to me as the cashflow currently stands. 

I've had the home inspection and wood destroying insect inspection so far and they both say for this house to be this old, the report wasn't bad.Problem: I feel like I may be missing something, so I am here to brain storm.

Without spending an incredible amount of time asking myself (because you all are the experts) what am I missing?

As a lender, it doesn't make sense to have money that can't be invested elsewhere but also is only earning interest when someone else decides.I'm currently considering a couple of options...Interest paid only on drawn funds, but with a larger minimum draw amount and a higher interest rate (~10%)Low rate (2-4%) paid on unused funds, moderate rate paid on drawn funds (6-8%)What am I missing?
