The math that sends people to the coast is simple. A paid off house in a landlocked suburb is dead money, and a pension that feels thin in Denver or Manchester feels generous in Vlore. Sell the house, keep the pension, and the arithmetic flips: the sale funds the move and the monthly check covers the life. What follows is twenty eight seaside towns grouped by region, from the American Gulf and Atlantic to the Mediterranean, the Balkans and the Black Sea, Latin America and the Caribbean, and Southeast Asia. Each region opens with its best value town. Because a house is the whole point here, every entry says what you actually get for the money: the kind of apartment or house that is typical there, what it costs to buy against what it costs to rent, and whether a foreigner can hold the title at all. Every figure is dated, because visa and ownership rules move faster than the tide.
Gulfport, Mississippi, the Gulf Coast Bargain That Leads This List

Start here, because nowhere else on the American coast gives you this much water for this little. Zillow put the typical Gulfport home at about $230,000 in early 2026, down roughly 1.6 percent on the year, with average rent near $1,124 a month. What that buys is usually a single story brick ranch on a deep lot a few minutes from the sand, or a raised cottage rebuilt after Katrina to a stricter code. Overall costs run about 15 percent under the national average. Americans buy freely, of course, and Mississippi does not tax Social Security or qualified retirement income, which quietly adds a few hundred dollars a month to a pension. Budget around $2,800 to $3,000 for a couple who arrive mortgage free. The catch is insurance: coastal wind and flood premiums are the line item that surprises everyone.
