Ok, "... rather than sell up and leave them homeless" indicates they were still living at home with their parents. This is a a generational thing, because I loved my parents to death and could not wait to become an adult and go off on my own. In fact, it was I that eventually moved back to my home town and brought my parents into my home so that they could live their remaining years in peace and not have to worry about their finances.no but just seems the thing a caring parent would do, provide a home for their children and grandchildren rather than sell up and leave them homeless especially when there are no affordable homes for the next generation. A home can actually last for more than one generation if its built right. It's not like people are all living in tents!
But if your parents don't do this then we have a Father in heaven who will provide, He never said you had to earn your way to heaven. If that was the case then only rich people would have homes there.
Being an adult comes with numerous phases: Gain an education, become independent, start a career, start a family, raise your family, retired from your career, and enjoy the latter part of your earthly life with sufficient financial independence to enjoy what you spent your entire life working on.
