Further, the reason for sale sub to may be because of some property deficiency that does not allow the property to qualify for new financing, or the property may not be worth the amount owed forcing the seller to “compensate” a higher than market price with either “easy or no qualifying” or a low interest rate.

The lender can using the acceleration clause of the mortgage make it 100% due and payable but that would just force you to refinance it into a different kind of loan.

Hello @Sa'Mara Roberts,This is a tough situation to be in, but it seems you're being forced to file a partition. 

Long story short, my portfolio's equity has grown to the point where the return on equity is so low that it has forced me to consider selling my 14 unit apartment building. 4 years ago when I bought this property for 445k and I dumped in 200k and has performed incredibly well and rents have grown, the building is now worth around 1.1M.

I know the typical value add on a SFH is to fix up kitchens and bathrooms, and forced appreciation with ADU’s or new bathrooms and bedrooms, but how can you do this in a MFH?
