Not part of the original OP post but I have 3 sets of friends or co workers who moved up to vegas from Hawaii after they retired. They all seem to like the move. I don't think they would have moved to Pahrump since it is "far" away from vegas. They find vegas more convenient.
As for me, I doubt I would move, especially to the vegas/Nevada area. I don't like the weather changes, too cold in the winter and too hot in the summer. I like Honolulu just fine, I can golf just about every week of the year. But I am lucky, I bought my condo over 25 years ago for under $100k and my mortgage (after refinancing a few times) will be paid off next year so after I retire I won't have that many large expenses other than the usual maintenance fees and utility fees, property and income taxes, etc. I feel sorry for the kids nowadays who can't afford to buy a place and have to pay high rent prices to live. No wonder we have such a big homeless problem in Hawaii. Unaffordable to many. Doesn't help that they are mostly building condos for investors and the rich. In Honolulu "affordable housing" is something in the $400k to $500k range, unbelievable. Where are the rest of the people going to live?
