Disagreement On Personal Property Conveyed At Closing, In

We are scheduled to close next week on a house that had several personal property items written into the OG purchase agreement/ contract that was signed by both parties. Important: This contract included a clause that the sellers wouldn’t be obligated to pay repairs that cost less than $750.

After inspections we negotiated with the sellers for a credit to repair several items that the home needs and included quotes from local contractors. The sellers found better quotes that made the repairs go under the $750 limit, but they signed anyway and so did we!

Now, they are taking a big ($1000+) item from their personal property list and saying that they sold it already and want it out of the contract.

Our agent says we don’t have any recourse because they agreed to repair things that they didn’t have to repair, under the $750 threshold.

“if we did not have in writing where they have given credit for items less than the amount of $750 then we may be able to fight this through. They did do that which was not a contractual obligation.”

Is this even related?

They also keep stating that they have a better offer being strung along that keeps “checking in”.

This feels similar to them taking a refrigerator at closing that was written on the contract except we have advance notice…

What legal recourse do we have? If we choose to delay closing, I’m afraid they will just jump on the other offer like they want to do.

Happy to chat in comments. I just want to understand, legally.
