I vote for 1st I'll take it. And then payment in reasonable/agrreable amount of time. I would frown on that buyer then backing out after a deal has been reached. Need a couple more days, sure. Backing out......Not so cool !!!
I know that when
I say, "I'll take it"......I mean it!! No if ands or but's. If I change my mind, too bad. It's mine to try and resell. I'd feel like a complete jerk backing out on a deal for no real reason. But that's just me. I know there are other things that are WAY more important in life that can change a situation.
If someone want's to think about it/mull it over. They better stay in touch, ask questions, pull my hair, or something... .
There are a handful of guys that I dealt with in the past that I would/could hold items for 4-6 weeks. I really try and be as flexible as possible for everybody.
