No, if a mortgage was recorded, it would have to be paid off, or the holder of the mortgage would have to agree to an assumption, or to write a new note/mortgage with the new buyer.

I had one owner who was stuck with only $700 of income for 4 months because it was the last remaining room lease before we could rent the house to a single lease holder.  

Are they foreign nationals on a work visa?

I assume the proceeds of the sale would go to pay back the tax certificate holder for back taxes, interest and court costs and then the overage would be split up by the heirs ?

It can just give the lien holder the right to accelerate the note.  

Make sure you have the right voucher holder.

Depending on whether you have US FICO, US bank, Visa, etc, the programs you can qualify will change.

Trust me they are ******** 5 they say they provide maid service well add this up cause i know they def dont pay the maids this 7 tennants times 89.00  yes not kidding they also demand that you either replace the air filters for the house lolololol. 7 tenants times 20 for filter no joke 140.00 for 2 air filters so how much do they cost at Lowe’s or Home Depot hmmmm for one less than 10.00 they demand you send a pic to them of you changing them if not they send the property manager of 500 names they call her runner,maintenance person ,lock changer , key holder, put up sign person 5 min later on floor, for any of those services  well thats a charge of 65.00.

You are the master lease holder.

In states where "source of income" is a prohibited discriminatory factor it would be illegal to only show voucher holders the rental.
