re: Real Estate: What are my legal obligations if there are title issues?

Buyers can walk pretty much whenever they want. Tell your lender to send you a letter of disqualification. They do it all the time. Additionally, dont sign another extension (assuming you have). Just let contract expire.

Me personally, I'd use this as an opportunity to parlay it into $.
They're invested by having the house off the market. Make it worth your while. Ask for something (or go big during inspection requests).

Im a house flipper fwiw. I have a minimum of 10 or 12 contacts per year that the buyer just walks. Can be for no reason at all.

There is very little protection for sellers. Lots of protection for buyers.

You can walk whenever you'd like.
