Irving, I think you and I are just thinking about different circumstances.
I'm envisioning a catastrophic financial meltdown, where everyone is hurting, unemployment skyrockets, and the dollar tanks severely. If all the worthless cash people have must be used to buy bread, Real Estate values will tank also, because few will have the money to buy it at pre crisis values. The potential market for your Real Estate product will fade away, and with that so will the price you can command for it.
