Additionally, I would like to attempt to do the process Owner/Builder with subcontracting work out as well as doing some of the work I'm comfortable with (I have some experience with bathroom & kitchen remodeling an am not new to the construction industry).

I will also be doing all the cosmetic things you can think of: paint, flooring, bathroom reno, kitchen reno, so I am open to carpenter or design suggestions.  

The store needs a deep clean of the floor, fridges, kitchen area, decluttering, etc., and it is in the Bronx, NY.

Improvements that drive the ARV the most: Roof, New Kitchen & Bathrooms, Flooring, Paint2.

Bathroom and kitchen need redone.

For me as well as the seller.First, you have to define Sub to financing.Do you mean the reckless kind where you overpay for a property, take over the financing and borrow from others to cover closing costs and holding costs when you have no money, no credit, no income, no reserves and can't tell a warranty deed from a deed of trust and you close on the kitchen counteror do you meanbuying below market value, already having a nice income, having reserves, using escrow and title, already understanding the due on sale clause, have done a lot of creative purchases and know when to use and when not to use creative finance and how to recover if something goes amiss?

That stopped when I stopped using third-party cleaners, but I also started to only leave enough for the stay.I use a small Dawn hand dish liquid that I fill between guests and larger hand soap dispensers in the bath and kitchen that I fill between guests. 

I renovated the kitchen with paint and cabinets.

I installed some updates like new flooring and Kitchen appliances.
