I don't think this will be like the late 1990's through the bust. We owned at Sea Bluffs in late 1999 before "my ships came in" namely, Adaigo and Bella Vita. Sold our place for a solid triple after all the owners were getting valuations monthly. I asked one simple question, "If our values are rising every month, why not the rental price?" Nobody bothered to answer that one, and as a financial advisor, decided to sell in 2004....took one day to sell and was sold for $50k more than appraisal.
That, my friends, is a bubble. Buying on spec before it is out of the ground and flipping it. Now, with cheap money from the Fed, people have figured out that they had better get their final resting place before rates move up. We got our slice of paradise last May and I can assure you that we will not flip and got it at such a price that we do not have to rent.
Love it here and maybe because of low interest rates, repaired balance sheets and being a bit older, buyers are realizing they better buy now and enjoy.
