The real estate broker knows what he would like but this buyer for ME property that just called that you have no history with, not much showing for details on your etch-a-sketch is not a "know exactly what you want" candidate.Whoa, not yet cowboy.
It starts with listening, active listening. Close pie hole, open two ear ports, listen. Ask a few questions like "tell me about your current home, what you like or don't like" and then you start to collect a top ten thumb nail collection of what this real estate buyer is hankering, wanting for his personal wish list.
Find out with pre-qualify what he can afford, keeping it real. But listening, not jumping to a quick role reversal of this is what you want. You insult a buyer insinuating you know what they want when you have no history, don't know what they want because they have not shared that with you. You're good, but not that good and a long long way from owning a fully functioning real estate crystal ball.
It is about the ME real estate buyer, not you. Example, guy on phone you just met wants a mobile home on acres, some ME land to build his own home in time behind that mobile. Using the existing well, septic, and as he and his partner can afford building, framing a home behind the mobile. Pay as you go...what a concept for a Bob Vila kind of guy with patience, know how and not wanting to do the head over heels in debt hokey pokey. Hey. If you take the approach "oooohhhh, mobile, gross" you are missing the mark.
Pushing what you would want is insensitive to what he asks for, spelled out in simple See Dick, See Jane fashion.
