Scenario: You have a spare room or basement suite. One of you thinks renting it out would help with the mortgage. The other isn't sure they want a stranger in the house. How do you decide?

The decision: do we become landlords?

Before discussing income splits, agree on whether to rent at all. This is a lifestyle decision as much as a financial one.

Questions to discuss:

  • Are we comfortable with a tenant sharing our space?
  • What kind of tenant are we open to? (Student, professional, family member, short-term/Airbnb?)
  • Who handles landlord responsibilities — finding tenants, maintenance calls, conflict?
  • What's our minimum acceptable rent vs. our ideal?
  • What are the legal requirements for landlords in our province?

When co-owners disagree

If one person wants to rent and the other doesn't, you'll need to find common ground. Options:

  • Trial period: Agree to try it for 6-12 months and reassess.
  • Conditions: Agree to rent only if certain conditions are met (e.g., long-term tenant only, no Airbnb).
  • Compensation: The reluctant person might agree if they get a larger share of rental income.

What you shouldn't do: One person unilaterally deciding to rent out space.

How to split rental income

Option 1: By ownership percentage

If you own 50/50, you split rental income 50/50. If you own 60/40, you split 60/40.

Pros: Simple, consistent with ownership.

Cons: Doesn't account for who does the landlord work.

Option 2: Offset shared costs first

Rental income goes toward mortgage/expenses before anyone takes a cut.

Example: Rental income is $1,200/month. You put it all toward the mortgage. Your individual contributions are reduced accordingly.

Pros: Reduces everyone's out-of-pocket costs.

Cons: No "extra" income to either person.

Option 3: Compensate the landlord

If one person does most of the landlord work (finding tenants, handling repairs, dealing with issues), they might get a larger share.

Example: 60% to the active landlord, 40% to the passive owner. Or a flat monthly "management fee" off the top.

Option 4: Hybrid

Rental income offsets costs first. Anything left over is split by ownership or effort.

How to split rental expenses

Being a landlord comes with costs:

  • Advertising and tenant screening
  • Repairs and maintenance (tenant-caused and normal wear)
  • Insurance (consider landlord or rental property insurance)
  • Potential vacancy periods
  • Legal costs if there are disputes

Common approach: Deduct rental expenses from rental income before splitting. Net income (income minus expenses) is what you split.

What to agree on before renting

Write down your agreement on:

  • Decision to rent: Both owners agree to rent out [room/suite].
  • Tenant criteria: What kind of tenant, minimum lease term, etc.
  • Income split: How rental income is divided (or used).
  • Expense handling: How rental-related costs are paid.
  • Landlord duties: Who handles what.
  • Exit clause: How to stop renting (notice to each other, not just the tenant).

Basic landlord obligations (Canada)

Landlord-tenant rules vary by province, but generally:

  • You must provide a safe, habitable space.
  • You need a written lease (required in some provinces, recommended everywhere).
  • Security deposits are regulated — know the rules in your province.
  • Eviction requires proper process — you can't just kick someone out.
  • Rental income is taxable — track your income and deductible expenses.

Before becoming a landlord, research your provincial rules or consult a professional.

Special case: Airbnb and short-term rentals

Short-term rentals have different considerations:

  • Municipal rules: Many cities restrict or require permits for short-term rentals.
  • More work: Higher turnover means more cleaning, key handoffs, and guest communication.
  • More income (maybe): Higher nightly rates, but also more vacancy and expenses.
  • Insurance: Standard home insurance may not cover short-term rental guests.

If considering Airbnb, check local regulations first.

Practical takeaways

  • Both co-owners must agree: Renting is a joint decision, not unilateral.
  • Agree on income split before listing: Ownership-based, cost-offset, or effort-based.
  • Document your arrangement: Tenant criteria, income split, expense handling, duties.
  • Know your obligations: Research landlord-tenant rules in your province.
  • Track income and expenses: You'll need this for taxes anyway.

FAQ

Can one co-owner decide to rent out a room without the other's agreement?

Generally, no. Major decisions like bringing in a tenant should require agreement from all co-owners. If your co-ownership agreement doesn't address this, you should discuss and agree before listing.

How should we split rental income?

The most common approach is to split rental income according to your ownership percentages. But you could also use it to offset shared costs, or split differently if one person does more landlord work. Agree before the tenant moves in.

What if the tenant damages the property?

Security deposit should be used first. Beyond that, repair costs are typically shared like any other maintenance. Consider landlord insurance to protect against larger claims.
