Love the refinancing twist to improve your returns even further.

So we bought a fixer, improved it, moved and instead of selling, we rented the last one out, and by this slower method we collected rental doors.  

This usually assumes many things such as improved financials of the property, value-added, lower rates, more experience, more lenders competition, ... etc3.

He likes to give back and help others improve.

Is there any major improvements that you could have taken?

If this is, you likely will not be able to take out any equity to use to improve the property.

That will make this (or anything in the same price range) a much safer deal, generally.If it's been remodeled, why did you figure 3K for repairs - just miscellaneous improvements you'd want to make?

use those funds to improve credit worthiness, and finance more rehabs. 

Exterior capital improvements are complete, except for a laundry facility we are planning to add. 

Hard part is making sure you can improve/add to the existing property or a development is more ideal.
