Consider an example: two friends have known each other since their children were in kindergarten together. Both are widowed now. One has a four-bedroom house that feels too quiet. The other's rent has gone up again. Over lunch, one of them says it out loud: "Why don't you just move in with me?" They both laugh, and then neither of them says anything for a moment, because it might actually make sense.

For many older adults, a friend or relative is the first person they picture when they think about sharing a home. In a 2024 AARP survey, 57% of women 50 and older said they would consider living with a friend as they age, but only 6% would consider living with someone they do not know1.

That instinct makes sense. You already know and trust this person. But sharing a home is different from sharing a lunch, and a relationship you treasure deserves some careful thought before anyone packs a box. This guide is not meant to talk you out of it. It is meant to help you go in with your eyes open and set it up so the relationship comes out stronger, not strained.

What can make it wonderful

The honest risks

The relationship is on the line. If a home share with someone you met through a program does not work out, you part ways. If a home share with your best friend or your brother does not work out, you may lose more than a living arrangement.

Knowing someone is not the same as living with them. You may know your friend's politics, her grandchildren's names, and how she takes her coffee, and still have no idea what time she goes to bed or how she leaves a kitchen. Our guide "Compatibility doesn't mean being alike" explains why enjoying someone's company and living comfortably alongside them are different things.

The hard conversations feel harder. Asking a stranger for rent on the first of the month is business. Asking your sister can feel impossible. The same goes for raising the dishes, the TV volume, or overnight guests. When those conversations do not happen, resentment grows quietly.

Old roles come back. Family members especially can slip into patterns set decades ago: the older sibling who takes charge, the child who worries, the cousin who always needed rescuing. Our guide "Could living with someone who isn't family be easier than you think?" looks at why.

Help can turn into caregiving. With a friend or relative, it is easy to drift from a ride now and then to daily care that nobody agreed to. Home sharing is housing. It is not caregiving, case management, counseling, or treatment. Trading help around the house for lower rent, or paying someone for help, can create employment, tax, and insurance obligations whether or not anyone intended it, so get advice before either of you agrees to it. Our guide "Help around the house is not caregiving" has more.

Money differences can strain things. If one person owns the home and the other is struggling financially, the arrangement can start to feel like charity to one of you, or like a debt to the other. Clear terms protect both people's dignity.

Ending it is harder. It can feel unthinkable to tell a friend or relative that the arrangement is not working. Without an agreed way to end it, people sometimes stay in a situation that makes them both unhappy.

Questions to ask yourself first

If most of your answers feel comfortable, that is a good sign. If some make you uneasy, talk them through with the other person before you decide. Their answers may reassure you, or they may tell you that the friendship is better kept as it is.

How to set it up so it works

The same tools that help people who meet through a program help friends and relatives, too. They may matter even more, because they take the awkwardness out of conversations you would otherwise avoid.

Money, benefits, and the law still apply

Being friends or family does not change the rules. A few things to check before you set the rent. Rules vary by state and change over time, so confirm the details with a free tax help site, Social Security, or local legal aid:

When another option may fit better

Sometimes, after talking it through, friends decide the relationship matters too much to risk, or that their daily lives would not fit. That is a wise outcome, not a failure. Some people then look at a matched home share, where a program helps them find someone whose routines fit theirs and whose relationship with them starts fresh. Our guide "The Golden Girls model, in real life" describes how that can work. Others decide they would rather keep living on their own, and that is a fine answer, too.

Clear terms are not a sign of mistrust. They are how you protect a relationship you care about.

Home sharing and older adults

Home sharing works at any age. Older adults are one of the fastest-growing groups sharing a home with someone who is not family2, and many more share with relatives. Whoever you share with, the same planning helps.
