🏡 Loan-to-Value (LTV): What It Really Means

When you're buying a home, one of the first numbers a lender looks at is your Loan-to-Value ratio, or LTV. It's a simple concept with a big impact on your mortgage approval, interest rate, and insurance requirements.

Let's break it down in a friendly, straight‑to‑the‑point way.

✨ What Is LTV?

Loan-to-Value (LTV) measures how much of the home's value you're borrowing versus how much you're putting down as a down payment.

Think of it like this:

  • LTV = What you owe
  • Equity = What you own

The higher your LTV, the smaller your down payment—and the more risk the lender takes on.

📊 How to Calculate LTV

It's a very simple formula:

LTV=Loan AmountProperty Value×100LTV = \frac \times 100

Lenders always use whichever is lower: the purchase price or the appraised value.

Example

You're buying a home for $500,000 with a $50,000 down payment:

  • Loan amount: $450,000
  • Calculation: 450,000 ÷ 500,000 = 0.90
  • Your LTV = 90%

🏷 The "Magic" LTV Buckets

LTV determines which mortgage rules apply to you. Here are the key categories in Canada:

🔹 80% LTV or Lower — Conventional Mortgage

  • You have 20%+ down payment
  • No mortgage default insurance required
  • Often eligible for 30-year amortization
  • Fewer government restrictions

🔹 80.1% to 95% LTV — High-Ratio Mortgage

  • Down payment is less than 20%
  • Requires mandatory mortgage default insurance (CMHC or Sagen)
  • Usually limited to 25-year amortization

🔹 Over 95% LTV — Not Allowed

Canadian rules prevent LTV above 95% for standard residential purchases.

💡 Why LTV Matters

LTV impacts several key parts of your mortgage:

1. Interest Rates

Surprisingly, high-ratio (insured) mortgages sometimes get lower interest rates because the lender's risk is covered by the insurer.

2. Refinancing Rules

If you're trying to take equity out of your home:

  • Lenders cap refinancing at 80% LTV
  • You cannot refinance to 95% LTV like you can when purchasing

3. Insurance Requirements

  • U.S.: PMI applies when LTV > 80%
  • Canada: Insurance is a one-time premium added to your mortgage (not monthly)

🔄 LTV vs. Equity: Two Sides of the Same Coin

  • If your LTV is 75%, your equity is 25%.
  • As you pay down your mortgage or as your home value rises, LTV decreases and equity increases.

Higher equity = more borrowing power + better rates + more flexibility.

🏁 Final Takeaway

LTV plays a huge role in:

  • Whether your mortgage is insured or conventional
  • What rules you're subject to
  • The interest rate you'll be offered
  • How much you can refinance later
