Finding and vetting the right co-buyer
Co-buying is a long financial relationship, not a house share. Here's what to ask, what to check, and the warning signs worth walking away from — before you view a single property.
Your best mate isn't automatically your best co-buyer
The right person is the one whose money habits, timescale and appetite for risk look like yours.
Someone planning to stay eight years and someone hoping to sell in two will crash into each other eventually — no matter how well you get on now.
Start with the dull questions. How long do you see yourself here? What would make you want to sell? What would you do if the boiler died next month?
Tap a card to flip it over.
Tap each one to see what you're really listening for.
Show each other everything, both ways
Before anyone makes an offer, everybody puts the same facts on the table: income and how secure it is, savings available for the deposit and fees, all debts and monthly commitments, and a credit report.
It feels intrusive — right up until you remember that each person's payment history will affect everyone else for decades.
Doing it both ways at the same time makes it fair rather than an interrogation.
- 1
Income
Payslips or accounts, plus how secure the job is and whether you're past probation.
- 2
Savings
What's genuinely available for the deposit and fees, and what's untouchable.
- 3
Debts
Cards, loans, car finance, buy-now-pay-later. All of it, monthly figures included.
- 4
Credit report
Pull it from one of the main agencies and swap. Missed payments show up here.
- 5
The emergency pot
What each of you could put in if the roof went tomorrow.
The awkward lifestyle chats people skip
Partners staying over, and eventually moving in. Pets. Working from home and who gets the quiet room. Noise, guests and how tidy is tidy. Whether a spare room can be let out for extra income.
None of these ends a deal on its own. All of them can end one if they're discovered rather than agreed.
Warning signs worth walking away from
Reluctance to share financial information. Pressure to move faster than you're comfortable with. Refusing to sign a Deed of Trust. Debt that turns up later, having not been mentioned. A track record of not sticking to shared commitments.
If you can, run a trial. Six months of a shared savings account with agreed monthly payments tells you more about someone than any conversation will.
