Seller wants to sell. Buyer wants to buy. Option contract in the middle

I represent the buyer. There is an option contract on the property with an investor/ loss mitigation company. I have been working on getting this contract executed for over three weeks. One of the main problems has been the listing agents lack of knowledge and personal issues as well as the broker.

We are very close to an agreement and then the government changes the laws and my client is having no luck getting a 30 fixed loan on this house based on the structure. My client is an A buyer with great credit.

The option was never recorded either.

The way I see it is this house will have to be sold to a cash buyer or the investor needs to step to the side and let the sale with the seller and buyer go thorough.

Any tips, connections, or advice on what to do?

Thanks,
