You've decided to move in together. Exciting, right?
But here's what most couples don't talk about until it's too late: money.
Three months in, you're fighting about who should pay for toilet paper. Six months in, you discover your partner has $40K in credit card debt. A year in, you realize you want to save for a house but they're still spending like they're single.
The stat that should scare you: Nearly 40% of couples who move in together break up within five years. Financial stress is the #1 reason why.
Here are the 10 financial questions you MUST discuss before signing that lease.
Question 1: How Much Do We Each Make?
Why this matters: You can't split expenses fairly if you don't know what each person earns.
What to share:
- Gross annual salary
- Take-home pay (after taxes)
- Any side income
- Bonuses or variable income
The conversation: "I make $65K before taxes, about $4,200/month after. I also freelance and bring in another $500-$800/month. What about you?"
Red flag: One person refuses to share this information. If they won't tell you their income, don't move in together.
Question 2: What Debt Do We Have?
Why this matters: Debt affects credit scores, ability to rent/buy, and how much money is available for shared expenses.
What to disclose:
- Student loans (balance and monthly payment)
- Credit card debt
- Car loans
- Personal loans
- Past bankruptcies or foreclosures
The conversation: "I have $30K in student loans, paying $350/month. No other debt. Do you have any loans or credit card balances I should know about?"
Reality check: If your partner earns $50K but has $800/month in debt payments, they effectively have less disposable income than someone earning $40K with no debt.
Question 3: What Are Our Credit Scores?
Why this matters: Landlords check credit. If one person has bad credit, you might get denied for an apartment or have to pay a higher deposit.
What to share:
- Current credit score (check Credit Karma or your bank app)
- Any late payments or collections
- Any judgments or liens
The conversation: "My credit score is around 720. I had one late payment two years ago but it's clean now. What's yours?"
Important: If one person has significantly better credit, consider having only that person on the lease (with landlord approval).
Question 4: How Will We Split Rent and Utilities?
Why this matters: This is your biggest shared expense. Get it wrong and resentment builds fast.
Three common approaches:
Option A: 50/50 split
- Works if: Incomes are within 20% of each other
- Example: Both earn $50K-$60K
Option B: Proportional to income
- Works if: One person earns significantly more
- Example: Partner A earns $80K (62%), Partner B earns $50K (38%)
- Rent is $2,000/month
- Partner A pays $1,240
- Partner B pays $760
Option C: One person pays more, other contributes elsewhere
- Works if: Income gap is huge or one person chose the expensive place
- Example: He pays 70% of rent, she covers all groceries and utilities
The conversation: "Rent is $1,800. I think we should split proportionally since you make more. What do you think feels fair?"
Question 5: What Counts as a "Shared" Expense?
Why this matters: Couples fight because they never defined what "split everything" actually means.
Definitely shared:
- Rent/mortgage
- Utilities (electric, gas, water)
- Internet
- Renter's/homeowner's insurance
Maybe shared (decide together):
- Groceries
- Household supplies (toilet paper, cleaning products)
- Streaming services
- Furniture
- Decor
Probably personal:
- Individual phone bills
- Personal car payments
- Student loans
- Clothes
- Personal hobbies
The conversation: "I think rent, utilities, internet, and groceries should be shared. But I'll pay my own phone bill and gym membership. Does that work for you?"
Question 6: Joint Account or Separate Accounts?
Why this matters: This determines how you actually pay for shared expenses.
Three setups:
Setup 1: Fully separate
- Each person pays their share via Venmo/Zelle
- Pros: Full autonomy
- Cons: Constant transactions, easy to forget who paid what
Setup 2: Joint account for shared expenses only
- Open joint checking account
- Each person transfers their share monthly
- Shared bills auto-pay from joint account
- Pros: Clean separation, no daily Venmo requests
- Cons: Requires discipline to fund it monthly
Setup 3: Fully combined
- All income goes into joint account
- All expenses paid from joint account
- Pros: Total transparency
- Cons: Zero financial privacy
The conversation: "I want to keep my paycheck in my own account, but let's open a joint account just for rent and bills. We each transfer our share on the 1st. Sound good?"
Question 7: Who Handles What Bills?
Why this matters: Someone needs to actually pay the bills. Assuming the other person "has it handled" leads to late fees and credit damage.
What to decide:
- Who pays rent? (Whose bank account?)
- Who pays utilities? (Venmo reimbursement or split?)
- Who tracks shared expenses?
- Who reminds the other person to contribute?
The conversation: "How about you handle rent since it comes out of your account, and I'll handle utilities and groceries? We can check in monthly to make sure everything's square."
Pro tip: Use Halfway to track all shared expenses in real-time. Both people add purchases, see balances, and avoid the "did you pay the internet bill?" texts.
Question 8: What Happens If Someone Loses Their Job?
Why this matters: Job loss happens. Having a plan prevents panic and resentment.
What to discuss:
- Do we have an emergency fund? (3-6 months of expenses)
- If one person loses income, does the other cover more temporarily?
- Do we expect the unemployed person to still pay their share?
- How long is the "grace period" before we need a backup plan?
The conversation: "If I lost my job, I have about 2 months of savings to cover my share. After that, would you be able to cover more rent temporarily while I find something? I'd pay you back once I'm working again."
Reality check: If neither of you have savings, seriously reconsider moving in together. One unexpected expense or job loss will derail everything.
Question 9: What Are Our Financial Goals?
Why this matters: If one person wants to save aggressively for a house and the other wants to live it up, you'll fight constantly.
What to align on:
- Are we saving for anything big? (House, wedding, travel)
- How much should we save per month?
- Is one person's debt payoff a shared priority?
- Do we want to retire early or live for today?
The conversation: "I want to save $500/month for a house down payment. Are you on board with cutting back on eating out so we can do that together?"
Common misalignment: One person grew up wealthy and doesn't think about money. The other grew up poor and is terrified of financial insecurity. These need to be discussed, not ignored.
Question 10: What Happens If We Break Up?
Why this matters: Nobody wants to think about this, but 40% of cohabiting couples split up. You need a plan.
What to decide:
- Who stays in the apartment? Who moves out?
- Does the person who moves out still pay their share until the lease ends?
- Who keeps shared furniture?
- Who's responsible for breaking the lease (and paying the fee)?
The conversation: "I know this is awkward, but if we ever break up, let's agree that whoever wants to stay can keep the apartment, and the other person finds someone to sublease their half. Fair?"
Legal protection: If you're not married, consider a cohabitation agreement (especially if buying property together). It's like a prenup for unmarried couples.
The Actual Conversation: How to Have It
Step 1: Schedule it Don't bring this up casually over dinner. Say: "Hey, before we move in, we should talk about money stuff. Can we set aside an hour this weekend?"
Step 2: Come prepared
- Know your income, debts, and credit score
- Think about what split feels fair to you
- Write down your questions
Step 3: Stay calm This isn't an interrogation. You're building a plan together.
Step 4: Use "I" statements
- Good: "I feel anxious when I don't know how we're splitting bills."
- Bad: "You never talk about money."
Step 5: Write it down After the conversation, document what you agreed to:
- Rent split: 60/40
- Groceries: Shared, tracked in Halfway
- Internet: Partner A pays, Partner B reimburses half
- Utilities: Partner B pays, Partner A reimburses half
Red Flags That Mean You're Not Ready to Move In
Stop. Do not move in if:
- One person refuses to disclose income or debt
- One person has secret spending problems (gambling, shopping addiction)
- You've never had a single conversation about money
- One person expects the other to "take care of everything"
- You don't have ANY emergency savings between you
- You're moving in to "save the relationship"
Moving in together doesn't fix relationship problems. It amplifies them.
What to Do After "The Talk"
Week 1: Set up your system
- Open joint account (if doing that)
- Download Halfway on both phones
- Add recurring expenses (rent, utilities, subscriptions)
Week 2: Test run
- Track one week of shared expenses
- See how the split feels
- Adjust if something doesn't work
Month 1: First money date
- Review the first month
- Discuss what worked and what didn't
- Make changes as needed
Ongoing: Monthly check-ins
- 15-30 minutes
- Review shared expenses
- Adjust budget if income/expenses change
- Celebrate wins (paid off debt, hit savings goal)
The Bottom Line
Moving in together isn't just about combining furniture and sharing a bathroom.
It's about combining financial lives—or at least figuring out how your financial lives will interact.
The couples who succeed:
- Have the money talk BEFORE moving in
- Document their agreements
- Track shared expenses transparently
- Check in regularly
- Adjust when things aren't working
The couples who fail:
- Assume everything will "just work out"
- Hide financial problems
- Never discuss who pays what
- Resent each other silently
You're not planning for failure by having these conversations. You're planning for success.
