If someone won’t pm you their cell based on the description you gave........they are not the person you are looking for.......that’s been my experience.
I’ve sold a lot here and the way you get a simple transaction is just the way your approaching it.........you already have interest from a few who are serious enough to pm a cell.
Describe it......offer pictures if they pm a cell number.......boom......set up the meeting and sell it with the serious buyer......it never fails.......especially when you are offering a bargain, let alone a fair price.
