I offered full price split closing.

My wife has a full time job that pays roughly $50k but I’m the stay at home dad who’s homeschooling our kids.

I’ve also been in touch with a company called Maintence supply headquarters, that provided me a very reasonable turnkey materials quote for each unit that included everything from door hinges to full appliance package.

We did allow painting but were specific about where (NOT in this location) and how much (she totally killed that budget and expected full payment!!!).

In this case, where you don't sound like you're doing a full rehab and you'll have a full mortgage, I would probably do 20k or more. 

What about the value of "hoods" as a RE investment and as a human potential?

I have an offer at full price the next day but am running into issues and questions from the real estate agent and buyer as neither of them are familiar with wholesaling. 

A little about me is that I'm new to investing but have years of experience in the commercial general contracting world which is what I currently do full time in D.C.

Someone gave me that advice and I listened to them. 6 months later I quit my job and have been doing this full time since '16 now. wouldn't have it any other way.

Put what's owed in writing with a serious note for filing next month not accepting partial payments if the balance isn't paid in full.
