Negotiating seller concessions depends on knowing what the seller is interested in. Outside of more money, one of the biggest things you can offer is speed and certainty. This is why all-cash offers and waived contingencies are so popular; they make it more likely that a deal will get done, and get done quickly. Especially if you're confident about the home you're buying, waiving contingencies is a great choice. It exposes you to some risk, but you don't have to put any actual money down, which means you can use seller concessions to buy those discount points.
