Before you permanently uproot your life, consider an extended trial run in your prospective retirement destination. Renting for several months or a year will give you a better sense of what it's actually like to live there.
Talk to the locals about what they love, along with their pain points. For example, many Floridians will tell you that they love the beaches, the warm winters, and the lack of a state income tax, but they've also been hard-hit by soaring property tax rates.
2. Compare overall housing costs
Many people have built significant home equity by the time they retire. Cashing in and buying a smaller home for retirement could free up money in your budget.
But don't just look at home prices. It's essential to consider the overall costs of housing, including property taxes and insurance. If you will need a mortgage, also consider that you'll likely pay a substantially higher interest rate if you locked in a low-interest mortgage in the past few years.
If you're considering a move to a condo or homeowner's association, don't forget about the association fees. Also, consider the potential financial hit in the event of a special assessment.
3. Look at the entire tax picture
If you're worried about taxes in retirement, your first impulse may be to move to a state with no state income tax. Or you may be toying with the idea of moving to a country with generous tax incentives for foreigners.
But be sure to consider the entire tax picture, including income taxes, property taxes, and sales taxes. States with no income taxes often have to levy higher property taxes or sales taxes.
