How Much Down Payment Do You Actually Need?

You've saved $25,000. You're ready to buy a $500,000 home.

Then you get to closing and find out you need another $15,000–25,000 that nobody mentioned.

The deal falls through. You're crushed.

This happens more than you'd think. Because beyond the down payment, there are closing costs, taxes, fees, and reserve requirements that first-time buyers often don't know about.

Down Payment Reality

The down payment is the percentage of the purchase price you pay upfront. Here's what different programs require:


Down PaymentProgramNotes
3.5–5%CMHC insured (first-time buyers)Minimum down, but you pay mortgage insurance (CMHC fees)
10–15%Many conventional programsBetter rates than 5% down
20%IdealNo mortgage insurance required, best rates

For a $500,000 home:

  • 5% down = $25,000

  • 10% down = $50,000

  • 20% down = $100,000
  • But that's only the beginning.

    The Hidden Cost: Closing Costs

    Beyond your down payment, you'll need cash for closing costs:

    Land Transfer Tax: Provincial tax on property transfer (varies by province, roughly 1–4% of purchase price)

    Legal Fees: Your lawyer's fee (typically $1,500–2,500)

    Appraisal & Inspection: Property assessment (~$300–500) and home inspection (~$400–600)

    Title Insurance: One-time premium (~$300–500)

    Adjustments: Prepaid property taxes, utility adjustments, interest adjustments

    Total closing costs: Typically 2–5% of the home's purchase price

    For a $500,000 home, that's another $10,000–25,000 needed at closing.

    Cash Reserves: The Safety Net

    Lenders like to see you have money left over after closing. This is called "cash reserves" or "seasoned funds."

    Typical requirement: 2–6 months of mortgage payments in a savings account.

    Why? Because life happens. They want to know you can keep paying if you lose your job, get sick, or face an emergency.

    For a $2,500/month mortgage payment, that's another $5,000–15,000 lenders want to see sitting in your account.

    Seasoned Funds: The 60-Day Rule

    Here's something that trips people up: Your down payment needs to be "seasoned."

    This means the money has been in your bank account for at least 60 days before your mortgage application.

  • Large deposits right before applying? Questions about where it came from

  • Gift funds? Need a gift letter from the donor

  • Selling assets? Document the sale
  • Lenders want to see a clear paper trail. They're protecting against money laundering and undisclosed debts.

    The Real Cash You Need

    For a $500,000 home, here's the reality:


    RequirementAmount
    Down payment (5% minimum)$25,000
    Closing costs (3% avg)$15,000
    Cash reserves (3 months)$7,500
    TOTAL$47,500

    And that's assuming you're going with the minimum down payment. If you're targeting 20% down to avoid mortgage insurance, you need over $100,000.

    The "Ready Money" Checklist

    Before you start house hunting, make sure you have:

  • □ Down payment saved and seasoned (60+ days in account)

  • □ Closing costs covered (2–5% of purchase price)

  • □ Cash reserves (2–6 months of payments)

  • □ Documentation ready (tax returns, pay stubs, bank statements)

  • □ Pre-approval letter (not just pre-qualification)
  • Know Your Numbers Before You Offer

    Nothing's worse than falling in love with a home and then finding out you're $10,000 short.

    Do the math before you start looking. Know exactly what you can afford, including ALL the costs—not just the down payment.

    When you're prepared, you're a strong buyer. You can move fast when you find the right home. You can negotiate confidently.

    And you won't be surprised at closing.
