@Eric Smith You are not going to like the mileage when you are traveling out to Ohio to chase a $500 rent that won't ever be paid, find the unit trashed, have to travel back because property mgr didn't handle repairs right and you need to chase down deadbeat contractor who will never return your money nor finish the work etc etc. 

My hobbies include yelling at the TV while watching sports and popping bubble wrap.

With that math I am seeing that my property should be worth $280 -$300k when I am finished and fully occupied.

This is including MEP work being completed, but no upgraded finishes at all. 

(www.realestateexpress.com) I'm in Southern California also (Pasadena) so my road to licensure includes three 45hr college level pre-license online classes (California Real Estate Principles, California Real Estate Practice, and California Real Estate Finance).

One of the pieces of work included was a complete rewiring of the house to remove the active knob & tube system.

However, I have the price appreciations and I have included them below:Those cities have seen some massive price appreciations.Best,Brad

Therefore, any offer price you make would include the realtors fees with the Owner and likely the leftovers that would have gone to the buyer's agent.  

My question is, as a wholesaler is it possible to construct such agreement whereas the cash buyer agrees that the son (a realtor) is the one who is able to list the property after the cash buyer has finished with the rehab.??

Most of the work was done after I finished my work at my W2 job and on weekends.
