Also, I would just be careful not to over leverage.

Maybe I'm simply just caring too much haha.

If it is more extensive then let the buyer take care of it.  

You would also need to be very careful to only hire licensed and insured subcontractors and gather a COI from each one of them you hire.

The rates will be a little higher but they won’t care much about your income.

I suspect that as part of what is considered in doing a full blown appraisal, your overall risk profile and DSR (Debt Service Ratio) will be looked at.You have to be careful about your assumptions and ensure that the stuff you're adding to your portfolio is capable of producing the income where that looks favorable, especially if you don't have other earnings (or much of them). 

The quality matters, so be careful what you select.

Chronically late, normally gets caught up, and takes pretty good care of the property.

Rents aren't keeping up with sale prices right now, so be careful what you buy.
