I’ll also add value I’ve seen she adds from a buyers perspective:

-she has access to a lot of off market listings via her networks. Sellers will somethings keep things off market so that when they sell, the tax base stays relatively the same - the appraisers don’t see a sale in the official pipeline -my wife also is really good at sending bespoke letters to target homes of folks not yet willing to sell. She’ll ID a group of homes in the buyers range, send them letters, and usually gets a 5%+ response rate. These are from folks who wouldn’t have sold otherwise
