Guess that depends on where you're leaving and where you're going to. Some places have great housing prices but property tax may be high while others may have crazy car insurance rates, still others will cost you much more in health insurance. It's all a balance and why you need to do your research ahead of time and look at ALL costs. For us going to AZ, the only cost increase we're going to have that I've found in health insurance but that's a no brainer since my wife will stop working full time and lose the insurance she currently has. We'll have no house payment, a little bit lower property taxes, homeowners will be a push, MUCH lower car insurance, MUCH lower car registration fees, food is a push, water bill will be almost half and gas for the vehicles is almost 25% lower.
Some places like Colorado give you tax breaks as you age. Your 1st $20K in income isn't taxable at age 55 and that goes to $40K at age 65. Tennessee has no income tax except on stocks, bonds, etc and that's at a 6% rate. They don't tax retirement income at all. They have no inheritance tax and the estate tax supposedly expired in 2016. I've been to TN a few times and it's a beautiful state but I don't think I could handle the summer humidity. There's a lot of options out there.
