Whether it's blizzards or wind or flooding as Global Climate change proceeds is going to make some properties more expensive than others

 So, if your area is vulnerable to flooding or other calamities (even serious earthquakes or fires) this land will become less expensive over time. However, richer people might still live there as long as fire and flood and earthquake insurance is available. But, when it isn't available anymore that land will drastically decrease in value after insurance of whatever kind you need no longer is available.

Insurance companies have to be realistic as to their expenses from payouts. So, as properties become uninsurable more then they are going to suddenly or slowly drop in value for reselling them.
