The pros of moving into multigenerational household
A few generations living under one roof is nothing new in US history. In fact, as much as 20% of all households in the US were actually multigenerational households when people frequently lived with their adult children. Nowadays, this trend is not as common, but there are some obvious advantages of multigenerational living to consider.

You can divide the household chores
Firstly, a family can function really well, even when the elders, the adults, and children live together. Household chores can be divided equally among the members of the family, with your grandmother doing the cooking, your dad doing the washing, you getting groceries, etc.
You can divide the household expenses
This is also applicable to household bills and other expenses. So, living with other members of your family could be beneficial for your budget, especially when there is more than one salary that is supporting the household. It is also easier to pay your rent or monthly mortgage if working members of your family participate equally.
You can take care of everything together
Otherwise, it is easier to do reparations around the house when you have someone to help you. This also goes for other types of assistance that you or your family members could need, such as when you are moving house. For instance, your parents could be struggling with driving in the wintertime, and you or your siblings can jump in and drive them when necessary.
Moving house is much easier
Also, it is easier to move house when there are many people that handle the packing, labeling, and moving furniture. You will be packed and ready to go in no time if everybody in your household puts in the weight.

The cons of moving into a multigenerational household
As we have seen, there are many benefits to living in a multigenerational household. One thing to consider is the fact that you may not have the same level of privacy. The noise, sounds, voices, music that are part and parcel of any household can be overwhelming to handle if you are used to having peace and quiet in your living space.
Also, moving into multigenerational household and having your parents around while you have kids may be tiring at times. Especially if you do not have a large home in which everyone has their own room.
