To a large degree relators are a commodity. If you agree with that premise then choose a relator through an affinity group. Usually credit unions have these arrangements. By doing this you can get a bonus, this does not cost you anything, it comes from the relators commission. Naturally, relator's dislike this arrangement. Because the affinity group is getting the bonus and not you, this is legal. The affinity group keeps some of the bonus and gives some to you.
Really it is a symbiotic relationship, they get some commission and you get 1,000 or so on a designer home purchase. It could be more or less depending on home value.
Here is one:
