85% of Cubans own their homes. ... However, there is a catch: holding title to a property does not give you the right to sell it. The only legal way to move in Cuba is by swapping residences—a slow, bureaucratic and often corrupt process known as the permuta (“exchange”), which requires finding two roughly similar properties and getting state approval. To avoid this hassle, some Cubans prefer to marry the owner of a property, transfer the deed, and divorce.
