The reason I say this is that with a 5+ unit a lender will evaluate based on NOI and a cap rate, so adding a 5th unit COULD (or could not) substantially increase the value of the building and make it worthwhile to refinance and pay off the existing loan (that is tied to the "old" quad) anyway.

Currently we would be at 8.5% interest rate.  

Don't let the idea of a low interest rate trap you from upgrading to size/scale.

-interest rates AND prices are high right now, which have REALLY hurt cash flow.  

There is a perfect recipe brewing where inventory is at an all time low, with interest rates significantly higher than we're use to, capitalized by the insane economic struggles that are going on in our every day lives.... 

I'm looking at monthly cost to seller vs. anticipated rental income, purchase price relevant to the ARV of the area and interest rate, balloon, etc.

With insurance companies canceling policies and raising rates has anyone uncovered a way to self insure rental properties?  

Rates are too high.

The amount of capital required depends on the city's appreciation rate.
