In one state I know an old person can defer the property taxes by signing up with a specific program.

If it stays on the market then consider a fresh offer (the same or lower) later.It could be that the people who will handle the paperwork and will actually approve the sale are unclear as to the condition.

By the way, they do have a mentorship program.

But our Declarations need to be approved by 80% of the Ho's and 75% of the mortgage holders.Good Luck,Jason

One thing they will encourage is refusing offers not presented on the approved forms.

If it was duly signed by the executor, or administrator with proper authority, and has no contingencies regarding all children's approval, what is the issue?

A few successful landlords have programs where they upgrade or refresh things in a rental even when the tenant is there.

I listed a short sale in January and we had to get 3 approvals from the lender to sell the property.

Certainly, for commercial properties, 80/20 combined would not be approved.

You could consider refinancing your primary residence using a HUD rehab loan (allows up to 97 ARV) for homeowners needing to make repairs as low as 5,000 (program will advance up to 50% of labor/materials at closing to minimize your out of pocket expense).
