How to Budget for Your First Home Purchase

Buying your first home involves far more than saving up for a down payment. Between one-time closing costs, ongoing monthly expenses, and the unexpected costs of homeownership, a realistic budget can help you avoid financial strain after you move in. Here's how to think through the numbers before you start house hunting.

Start With Your Total Savings Goal

Your down payment is usually the first number that comes to mind, but it shouldn't be the only one. In Canada, minimum down payment requirements depend on the purchase price: 5% on the portion up to $500,000, 10% on the portion between $500,000 and $1.5 million, and 20% on homes priced at $1.5 million or more. Homes purchased with less than 20% down typically require mortgage default insurance, which adds a premium to your mortgage balance.

To illustrate, on a $500,000 home, a 5% down payment would be $25,000, while a 20% down payment would be $100,000. Beyond the down payment, you'll also want to set aside funds for closing costs, moving expenses, and an initial cushion for repairs or furnishings. Many financial professionals suggest budgeting an extra 1.5% to 4% of the purchase price for closing costs alone, depending on the province and specific transaction.

Factor In Closing Costs Early

Closing costs catch many first-time buyers off guard because they're due on top of the down payment, often within the same week you take possession. These can include land transfer tax (which varies significantly by province and municipality), legal fees, title insurance, home inspection fees, and adjustments for prepaid utilities or property tax.

First-time buyers in Ontario, British Columbia, and some other provinces may qualify for land transfer tax rebates, which can reduce this cost. It is worth checking what rebates or credits apply in your province before finalizing your savings target, since this could meaningfully change how much cash you need on closing day.

Estimate Your True Monthly Costs

Your mortgage payment is just one piece of your monthly housing budget. Property tax, home insurance, utilities, and, if applicable, condo fees all need to be factored in. Lenders typically look at your Gross Debt Service (GDS) ratio, which compares your housing costs to your income, generally aiming to keep this below 39%, though exact thresholds can vary by lender.

For example, if your gross monthly household income is $7,000, a GDS ratio of 39% would suggest keeping total housing costs, including mortgage, property tax, heating, and half of any condo fees, around $2,730 per month. This is illustrative only, as your actual qualifying amount depends on your income, debts, credit profile, and the specific lender's guidelines. Building this full picture, rather than just focusing on the mortgage payment, can help you avoid being house rich and cash poor.

Build in a Buffer for the Unexpected

New homeowners often underestimate how much cash gets absorbed in the first few months after moving in. Appliances may need replacing, window coverings and basic furniture add up quickly, and unexpected repairs can appear even in newer homes. Setting aside a separate fund, ideally a few thousand dollars depending on the size and age of the home, can reduce financial stress during the transition.

It's also wise to maintain some savings outside your home purchase fund entirely, so a job loss or unexpected expense doesn't put your mortgage payments at risk. A mortgage professional can help you stress test your budget against different scenarios, including rate changes at renewal, so you have a clearer sense of what's sustainable long term rather than just what you qualify for today.

Key Takeaways
