I have no idea what the market is like in Walnut, but if I saw a seller here pull the de-list/re-list trick *and* only dropped the price $8,800 on a $1.5 million dollar property, I’d say he’s pretty attached to his price (and maybe just a bit delusional).
That said, it really comes down to what you can lease it for and if you think the added payment option is worth it to you. Tough to research “fair market” on a lease like that though. I’d do your best, make him an offer and see what he comes back with.
