@Tony F. This might go over better elsewhere - in CA I’d imagine it could get messy. In NC, when two or more parties own property You can file what’s called a petition to partition. I understand it’s about $15,000 in North Carolina. However if one party wants out cheap, you could potentially have a deal.
In particular there is one investor here who will buy a non-owner occupied interest, usually an out of town inheritor where there are others who have inherited, mortgage it to full value and then File a partition suit. It goes to auction to courthouse steps and no one else bids on it because its sold subject-to the mortgage. He gets it cheap. Other party gets screwed.
It could backfire for you in a few ways. First a title search would be necessary. I assume don’t know what debts are going to need to be paid out of the estate or how RE is handled in probate when it must be sold to settle debts. a potential Medicare Lien would affect the deceased’s share and could make t messier.
If you came up with the price you want to pay for the property, halved it and deducted the holding costs plus potential partition lawsuit costs , and then owner financed 100% it would seem a reasonable bet to buy the 1/2 interest.
Please let us know how it works out.
