Don't create conditions that create unnecessary roadblocks for buyers agents and their buyers. The bottom line is this: The purpose of the listing is to sell the home for the best price and terms. No more, no less.
A real estate transaction is seldom a completely smooth ride. This has been particularly true since the financial crisis of 2008. From appraisal issues, to title issues, to unexpected glitches in the lending process, there can be quite a few obstacles between the signing of a contract and a closing. Agents handle many transactions. We've been down this road before and can anticipate the problems preventing many of them from asserting themselves.
Traditionally, it is thought that (real estate agents) fill out a few forms, stick a sign in the ground, throw a listing onto the MLS and disappear. Then we reappear magically at closing to collect a ginormous check.... If it were that simple, homes would fly off the shelf and listing agents as well as buyers agents would have disappeared (a long way back).
Don't try to beat the market! This is one of the biggest mistakes I see. Instead of dealing realistically with the market that they are given, some buyers dig in their heels and try to hunt down the last bargain in Westchester.
Downsizing can be challenging. But one thing many didn't expect was "sticker shock". Downsizer's are finding is that the slick townhouse or condo they have their eye on can cost almost as much as what they can sell their far larger single-family home for.
