When moving into a rental home with roommates, you need to figure out how to split up the rent in a way that is fair.

What would you do if you were moving into a four-bedroom home and you and your girlfriend were taking one bedroom, and your friends were taking the master bedroom and one other room for their child? The rest of the house was shared among all of you.

That is what the friend group in this story is doing, but they are disagreeing about how the rent should be split up. This young couple feels that they shouldn’t have to pay half the rent when they are only getting one (smaller) bedroom.

I agree with them, and they should not pay half of the rent. Read through all the details below and see how you think it should be split up.

How to split rent with roommates who are also our friends?

My girlfriend and I will be moving in with our friends, and are having some trouble figuring out how to split rent!

Background: we will be moving in to a 4 bd house. It will be me, my gf, our two friends who are a couple, and their 4 mo old son. total rent is $1,836

  • They will be taking the master suite with a walk in closet and private full bath.
  • They are planning on making one of the rooms a nursery for their son.

Here’s the plan for the other rooms.

  • My girlfriend and I will be sharing one of the rooms.
  • We will all be sharing the extra room as an office/guest room.
  • We all have access to the shared spaces such as the garage, kitchen, living room and the basement (if that matters lol).

The friends should definitely be paying a larger share.

How do you guys suggest we split?

Per room makes sense to me but the numbers they suggested were us paying more than what I thought we would be.

This isn’t a situation where you just split the total cost by how many people will be living there. Their friends have two bedrooms, one of which is a master suite. Clearly they need to be paying well over half of the rent payments.

Read on to see if the people in the comments have any recommendations on how exactly this should be done.

Yup, open communication is essential.

This all needs to be figured out and in writing before anyone moves in. Things like this can ruin a friendship even when people have the best of intentions.

Having a serious conversation about what each of them wants and what they think is fair will help to get through this quickly.
