Oh, right, I agree. I guess my further point is that I'd prefer that after you close the sale and finish the transaction, you're sure you have the money. Cash and some electronic transfers give you that, while checks don't.
one surprising use of a check is that one could write five checks, each with an amount and further away date.. e.g. dated the first of the month for the next four months. Those checks are now a reliable source for a loan in cash, since you signed each one. there are many other examples..
that is absolutely false IANAL
they say a Federal Bank can do that. I was talking about contracts between private parties (see above)
you neglected to say "bank" .. you said it as if anyone can do it. Look at what you wrote
