I have considered it for three weeks (the two I'm on OBX and the following week) every year since 1986.
Purely financial arnold. When I go on vacation to OBX, I must stay oceanfront. In my opinion if you are going to stay at the beach, then stay at the beach, or why bother. Therein lies the problem in that I would want to purchase oceanfront. I know, it stupid, but that is the only thing I would buy. But of course, I would need to be extremely wealthy to first afford to purchase the property, second to maintain it, and third not to worry if it got destroyed in a storm and my property was rendered worthless.
I remember when first when up to Whalehead Beach you could buy oceanfront lot for $20,000. OMG was that tempting!
