The contract in general states nothing along the lines of cosmetic repairs can be used as a rebuttal.

For most of the house, I've done nothing but cosmetic updates and in doing so changed many/most of the outlets to a new color and in doing so, bought three prongs even though the house is 2 wire romex.

(My offer was made prior to the major Corona Outbreak in the US)It's a triplex in Dunellen, NJ (B- Neighborhood) I would be house hacking and there's is a massive fully paved lot in rear of the home that has a heated garage with a gated entrance (Between 1-2 car garage) which tenants don't have access to and is not rented since the owner kept it for his son who is a mechanic.The house needs a good amount of repairs such as stucco siding repairs, lot re pavement, new furnaces, and cosmetic updates.

If there is any rehab to be done, it would only be cosmetic in nature. 

You don't need to say you are going to flip it, Banks think right there that you will need a construction loan, even if all you're doing is cosmetic fixes.

Cosmetic rehab What was the outcome?

But an easy way to think about it is “cosmetic rehab”.

Or a Doctor to perform surgery on you before graduating from Medical School?

This is not brain surgery.

I made some small changes to the property heating system and other small cosmetic upgrades.
