I wrote the Far 9 contract and next to the financing contingency paragraph I checked off seller will apply for conventional, FHA and VA financing.
Probably the "Seller" wasn't applying for anything.
Does your form specify that the Buyer was to make application to a "financial institution" known for providing such financing ? I doubt that an Individual Investor would suffice.
We have a denial letter from the investor inside the commitment period.
It may be that a denial letter from the Mortgage Broker, who originally arranged the Financing, would be more in keeping with the terms of the P&S than the letter from the Individual Investor. That might satisfy the Seller's Attorney; but it sounds like you may be beyond that point.
Here, anytime we have a disputed deposit situation, our P&S prescribes that we immediately place the funds into the hands of a "Court of Competent Jurisdiction". Luckily, most of my defaults have gone UN-Disputed, and I have been able (after the required waiting period) to pay the Deposit to the Seller. Here, the Listing Agency gets to keep 50% of those Defaulted Deposits (not to exceed the amount of the Commission that would have been earned), so I have at least received something for my headaches. Good Luck.
