Lender Fails To Close

[Larry W Boyd]

Started with 6 month Bridge loan, Oct, 2022. Started refi to long term fixed rate rental loan, April, 2023. After 3 extensions and 7 months time, costing $4900 in points, and not including appraisal fees, lender informs buyer they can't close the loan. Borrower is now faced with finding a new loan source, defaulting on the bridge loan or selling the property. What responsibility does the lender bear for not getting the refinance closed? Are there any legal remedies for the borrower?
