And, of course, practice is the key. Only your own experience can answer that, since it is different for every person. But some basic information may help you in your investigation. Foreign residents and tourists can own a house and property in Costa Rica, and there are houses, condos and apartments available for rent in most areas of the country. And up, depending on your choice of location and type of house.
Location also dictates the house prices, whether buying or building.
The cost of an automobile is relatively expensive in Costa Rica. While visiting, check around for prices on the type of car you would prefer. Some people ship their own cars from home, so check the cost of the import tax and shipping charges. Your decision to bring your personal household goods should be carefully evaluated. Contact others who have done it and consult with them.
