Great find on this website, could be helpful to others trying to find average cost vs value add in projects: http://www.remodeling.hw.net/cost-vs-value/2018/

finish the project etc.I use a step in agreement when I do these..

@George Genovezos,Checkbook IRA (aka IRA-owned LLC) is not a DIY project.

My cash flow after all expenses is projected to be $2,592.

   I've been  in the construction and woodworking industries for ~25 years now, and I'm finally looking at investing into my own projects.

It will be hard to wholesale because a lot of buy and hold investors don't take on giant projects like this and many flippers don't deal in multifamily.

For estimating purposes you should plan on the lower appraisal numbers in your analysis and when you have the cost to do the project make a decision based on that. 

Actually new construction development project.

All in all, I'm projecting approximately $3,000 in rehab per unit ($12,000) plus $6,500 in exterior work plus $5,000 to update the electrical with a $3,000 contingency reserve and a $2,000 management reserve - about $30,000 total.  

If I do not project at least 20% short term return, I am not interested and my conservative ROI estimates so far have always under predicted my ROI.
