Tap Home Equity to Buy Your Second Home

Whether you want a cottage, a vacation home, or an investment property, tapping your home’s equity can be an effective way to finance a second residence.

“Many prospective buyers don’t have the liquid cash required to buy a second home outright,” says Maxine Crawford, a mortgage broker with Premiere Mortgage Centre in Toronto. “They may prefer not to sell investments or redraw savings. Using home equity allows a buyer to leverage the value already built into their primary property to fund a second property purchase, either partially or in full.”

What is home equity?

Home equity is the portion of a property’s value that you own outright: the difference between the home’s current market value and the outstanding balance on your mortgage. To calculate your equity, subtract the remaining mortgage balance from your home’s estimated market value. For example, a house valued at $800,000 with $300,000 left on the mortgage represents $500,000 in equity. If your mortgage is paid off, your equity equals the full market value of the home.

What is a home equity loan?

A home equity loan—often called a second mortgage—is a loan secured by the equity you’ve accumulated in your home. Lenders commonly allow borrowers to access up to 80% of the property’s value when combining the first mortgage balance and the new lending. The borrowed funds are secured against the property and must be repaid under the terms agreed with the lender.

How to use equity to buy a second home

You can use home equity as collateral to borrow funds for a second property. Several common methods let homeowners access equity:

Mortgage refinance: Refinancing replaces your existing mortgage with a new one, either with your current lender or a new lender. Refinancing may let you borrow up to 80% of your home’s value, including the amount still owed on the original mortgage. The refinance proceeds can be taken as a lump sum to help purchase a second property, but you should factor in any prepayment penalties or closing costs when switching lenders.

Home Equity Line of Credit (HELOC): A HELOC behaves like a revolving line of credit secured by your home. Typical maximums range up to 65% of the home’s value, though some lenders allow higher combined limits. HELOCs usually carry variable interest rates tied to the lender’s prime rate and can be more flexible—borrowers only pay interest on the amount they draw. HELOCs can be useful when you want ongoing access to funds for a down payment or renovations on a second property.

Second mortgage: A second mortgage is an additional loan registered against your property while your first mortgage remains in place. Lenders may allow access to up to 80% of the home’s appraised value when combining first and second mortgages. Because a second mortgage ranks behind the first mortgage in priority, lenders typically charge higher interest rates to compensate for the increased risk.

Reverse mortgage: Available to homeowners aged 55 and older, a reverse mortgage lets you convert a portion of your home’s equity into cash—often up to 55% depending on the borrower’s age and the property’s value. Reverse mortgages generally have higher interest rates and do not require regular payments; interest compounds until the loan is repaid, usually when the borrower moves or passes away.

Options for leveraging equity in your home

Each option for accessing equity affects how much you can borrow, what interest rates are available (fixed, variable, or both), and how you receive the funds. Below is a summary of typical limits, rate options, and how funds are disbursed.

	Credit limit	Interest rate options	Financial impact	Access to money
Refinance your home	Up to 80% of appraised value (including current mortgage balance)	Fixed or variable	Your original mortgage terms may change; you could pay a new rate on the refinanced balance	Lump sum to bank account
Second mortgage	Up to 80% of appraised value (including current mortgage balance)	Fixed or variable	Usually higher interest than your first mortgage due to increased lender risk	Lump sum to bank account
Home equity line of credit (HELOC)	Generally 65% to 80% of appraised value (varies by lender)	Variable only	Rate and interest fluctuate with the lender’s prime rate	Revolving access, similar to a bank account
Reverse mortgage	Up to about 55% of appraised value for eligible borrowers	Fixed or variable	Higher interest than traditional mortgages; interest accrues until repayment	Lump sum or instalments

Pros and cons: Buying a second home with home equity

Using home equity to purchase a second property brings advantages and risks. Weigh these factors carefully before borrowing against your primary residence.

Pros

• Leverage an existing asset: Accessing home equity lets you finance a second home without liquidating investments or tapping savings.
• Potential tax benefits: Depending on how you use the second property—rental or business—certain expenses may be tax-deductible. Consult a tax professional for guidance tailored to your circumstances.
• Flexible borrowing: HELOCs and refinances offer different structures, including interest-only periods or revolving credit, which can provide flexibility for cash flow management.

Cons

• Higher overall debt: Borrowing against your home increases total liabilities and monthly payments. Variable-rate products can push payments higher if rates rise.
• Risk to your primary residence: Using the home as collateral means missed payments could lead to foreclosure on your primary home.
• Fees and closing costs: Appraisals, legal fees, penalty charges and other costs can offset the financial benefit of accessing equity.
• Market risk: A downturn in property values could leave you owing more than the combined worth of your properties.
• Reduced emergency buffer: Tapping equity reduces the financial cushion available for unexpected expenses or future goals like retirement or renovations.
• Ongoing costs: Second properties have recurring expenses—maintenance, insurance, property taxes and management costs—that affect cash flow and lifestyle.

How soon can you pull equity out of your home?

Lenders have varying rules about how soon after purchase you can refinance or draw on equity. Some require a minimum waiting period—often a year or more—while others evaluate requests case by case. More importantly, equity must first be built: as you pay down your mortgage and as your home’s value changes, your available equity grows.

The process of accessing equity also takes time. You’ll typically need to apply, undergo a property appraisal, and pass credit and income checks. Depending on the lender and the type of financing, funding can be available in a matter of days for alternative lenders or several weeks for traditional lenders.

Should you use home equity to buy a second home?

Deciding whether to use home equity for a second home requires a clear-eyed assessment of your financial situation and long-term goals. “Using home equity can help build net worth and provide liquidity for investments like a second home,” Crawford notes, “but it also raises monthly obligations and may impact lifestyle and future plans.”

Consider the total cost of borrowing, including interest, fees, and the effect on cash flow. Also think about contingency plans if property values fall or if unexpected expenses arise. If you plan to sell your primary residence, any outstanding financing tied to it will need to be repaid, which could affect proceeds available for other uses or estate planning.
