The property sold for 330K - that's an ROI of 15-30% per year assuming no loan.

i would be purchasing the property with an FHA loan. and im also looking for solid cashflow + long term holding 

The bank I have been talking to for the loan / construction loan seems to be willing to apply that logic. 

I am considering selling a single-family rental in DC and/or looking for a new commercial loan to purchase the building as much as I (or we if my brother decides t partner with me) can to be a majority owner.

For a lender to request a loan in full – they stop making money on it.

I know folks who bought strip malls and multi-tenant retail in 90s for 5-10 cents on the dollar at auction from Resolution Trust Corp after Savings and Loan crises in Texas, We are now going through similar deleveraging event after super frothy period in Multi-Family due to 0% fed funds x 20 yrs and many properties bought at 3-3.5 cap rates, especially in austin/dallas/H-town. 

Since all assets have already been pledged, offer the seller your stock in the acquisition company as security for the seller financed loan.  

Also would come with the stress of a loan, and debt servicing.

Another option was using equity to buy a 3rd home with FHA (the first 2 loans were under VA).

My current plan was to take out around 250k by refinancing to a 550k 7% loan from a $290k 3.25% interest loan.
