For me, the cash flow would need to be very good and sustainable (not above market rents).

Boring things like average purchase price to average income in an area ratios being one of the most stable and time tested. 5-6x income = average sale price is long term sustainable.

Partner A: Owns and runs a business, has comfortable consistent cash flow to sustain estimated payments for such a property but minimal credit history.

There may be other resons to do different things with the funds, but if you are deciding between those two choices that's what I'd do.

You do not want to pay a price for the building based on an amount that is not sustainable for that business.

I would have much better luck in my endeavor and most likely start moving forward in my progression to self sustainable income.   

I'd appreciate some comments as to whether this property, and the quality of the rehab from the photos, is one that can command the $1,250/mo and whether or not it can sustain this in the long run.https://drive.google.com/folderview?

Depending on what price point you are talking about just bringing the sustainability rebate/grant/credits etc experience might not make sense for the developer (they would generally contract with a consultant to handle this).  

"It is possible that bond markets will become worried about the sustainability [of yearly deficits over $1 trillion], and we may find ourselves facing higher interest rates even today."

We are expecting light rail also, between Durham, Chaoel Hill, and Raleigh.I think the reason people are moving here is, because while the costs of living are climbing, they are still lower in relation to other larger cities, but offer a more sustainable career path by transitioning here during this window of time to establish yourself before the economic boom in this area slows down.
