He says the house is set up the same as a regular house but he took the bathtub out .

(This is assumed since the situation is fluid and changing regularly)

So now, I have 2 outlets coming from presumably the same line, supporting regular household items like a pc, and phone, and a lamp.

But, I think you can still find a banker to give you a regular mortgage or a HELOC and count the rental income.

My situation may be a little more complicated than a regular rehab because I am hoping to enlarge the width footprint of the back of the house toward an existing 3’ wide walkway/alley that provides rear access to the houses perpendicular to me on the cross street.    

I am hopeful that this is temporary and we will soon return to regular business.

The "extenuating circumstances" items in the contract refer more to natural disasters, severe weather, illness or death than they do to cold feet or market conditions.

It depends on your situation-your reserves, your income (not rental income, but your regular work) and your bills. 

Human nature is funny this way, we forget quickly and get used to new circumstances fast.

A few people suggested I still try to close by finding a new lender, including my wife, and I am going against my own nature by shutting down my desire to jump in right now.
