Valuable and extremely important. We should consider all the experiences we have. They give us the courage and consciousness of why we do everything. For example, housing. Young people often deal with a common dwelling. It's also a good experience for someone who hasn't lived with anyone before. Everyone should probably try it before they get into something bigger. For something bigger you need money and it's more complicated, of course you can look at the comparison of mortgages where you choose the best.
Of course, if the young couples wanted to deal with something bigger, it is probably premature to not try to live together, for example, in the already mentioned apartment. It's an ideal solution. They may not be theirs, it is enough to move to a smaller place where the rent will be paid. The ideal solution for young couples who really want to try it out if they would work together.
