Sure, if the money is there. But until the matter is finally resolved (appeals run out, and a check is cashed) how does anyone know that there will be money available for a realty purchase?
What if someone contracts to buy a home today with $20,000 in cash due at closing in 60 days, money that will be generated from the settlement of a suit. And what happens if the suit is delayed? Money at closing is still required, and if the buyer does not close, there could be substantial damages—and maybe another suit.
