If you move to Thailand at age 50+ or above, meet the love of your life and get married, and she wants a house?
Be very conscious of signing up for a long term mortgage if you do not have the cash outright to buy a house.
Taking out a 30 year mortgage when you are age 50+, if you can only afford the monthly payments the next 30 years, is a high risk trapping your family with a mortgage they may or may not be able to afford in the future and will force them to have to sell/move when you die.
You may be living on a pension or social security and can afford the monthly payments, however, what about when you die?
Do you have enough savings to pay off the mortgage?
Do you have enough life insurance to cover the mortgage?
Can your family afford the pay the mortgage themselves?
Before making any mortgage decisions in the here and now, think hard what happens during the 30 year span of the mortgage.
If you die will be hard enough, if you die and your family has no way to finish paying for the house could be even worse.
Think wisely.
