First thing that jumps out to me is that he put "All Stock" in his ad....That's evidently not the case. Deception always makes me weary. And second, he states he's selling it because he has "Too Many Toys"....If it is a fact that he just purchased it a few weeks ago, why would he have bought it if he had "Too Many Toys"
I may be looking into the wording a little too close, but I'm very cautious. I'm in Construction Management and contract wording is something I review on a daily basis. Little indicators jump out at me.
