I probably should not have said "never", but it would be out of pocket and not the closing company fee. In New Orleans there is a huge tax that has to be paid but can be bypassed with a quit claim deed. I am sure there are other locations that have expensive government charges.
I inquired recently on using First American Title which was linked within Redweek. The buyer wanted to use them. They wanted about $1,100 to close on an timeshare in HHI. They were hiring a closing company in SC since they do not handle closings there and also hiring an attorney. Needless to say the whole thing was beyond ridiculous. Obviously >$500 exists but it's unnecessary.
My no greater than $500 is based on not less than $350 as the closing fee, $125 for Marriott ROFR & transfer, and the rest as county recording. There are plenty of reliable closing companies that will fall within the $500 and that includes handling the escrow.
