At this point I think the consensus is you need to find out exactly what is owned as lots of speculation.
Have dad copy what he has and get to you.
Hopefully enough info to go on line to County Clerk and get deed.
If a contract number can open an on line account.
Can also call Wyndham 800-251-8736 option 2 and then 3 and ask to check out. Will have to fake a little so have owner's address, ID number from owner's card, phone number, etc. handy.
At this point ball is in your court.
May need limited POA to resolve.
