Ontario Real Estate Investors: What the HST Rebate Really Means for Your Numbers

Could HST relief make a new construction rental property a better investment? For eligible Ontario investors, the savings could be substantial—but the amount you may recover is only part of the story.

Following a conversation with Mark Weisleder of RealEstateLawyers.ca, hosted by the Ontario Real Estate Association (OREA), I wanted to share the practical implications for investors considering a new build.

My biggest takeaway: understand both the property’s cost after rebates and the cash you need to complete the purchase. Those numbers can be very different.

How much could an eligible investor recover?

Ontario’s enhanced rental rebate, combined with the existing provincial rental rebate, can return up to $80,000 of the provincial portion of HST.

Eligible landlords may also qualify for the Ontario New Home Affordability Payment, providing relief equivalent to the federal portion of HST, up to $50,000, reduced by any federal rental rebate entitlement. Together, the relief can reach $130,000, including existing rebates. CRA rebate details

Here are some illustrations:

Purchase price before HST	HST at 13%	Potential combined relief	Purchase cost after relief*
$600,000	$78,000	$78,000	$600,000
$700,000	$91,000	$91,000	$700,000
$900,000	$117,000	$117,000	$900,000
$1,000,000	$130,000	$130,000	$1,000,000
$1,200,000	$156,000	$130,000	$1,226,000

These examples assume full eligibility and fair market value equal to the purchase price before HST. They exclude financing, land transfer tax, legal fees and other adjustments. Relief depends on fair market value and applicable program rules.

Plan for the cash required upfront

For investors, the application process matters just as much as the potential savings.

The builder cannot pay or credit the Ontario enhanced rental rebate to a purchaser/landlord. You must apply directly to the CRA, so your financing plan needs to account for the tax payable before relief arrives. CRA application rules

Consider a property priced at $700,000 plus HST:

• The purchase amount, including HST, is $791,000 before other closing costs.

• Deposits and mortgage proceeds cover part of that amount.

• You need sufficient funds to cover the remaining balance and closing expenses.

• If you qualify for $91,000 in combined relief, your purchase cost eventually returns to $700,000 before expenses.

That last step happens after you receive the relief. Until then, the money needs to come from somewhere. If you borrowed the full $91,000 at an illustrative annual interest rate of 6%, interest alone would be approximately $455 per month. Your actual cost depends on how much you borrow, your rate and how long the funds remain outstanding.

Total relief and additional savings are different numbers

A $91,000 recovery does not necessarily represent $91,000 in new savings.

For an eligible $700,000 purchase, the existing Ontario rental rebate could already provide $24,000. Compared with that baseline, $91,000 in combined relief represents $67,000 in additional savings. CRA rental rebate guide

This also makes advertised pricing worth a closer look. If a builder quotes a price “including HST, net of rebates,” ask for a written breakdown showing:

• The purchase price before HST.

• The total HST payable.

• The rebates assumed in the advertised price.

• The amount you must fund to close.

That breakdown helps you compare properties on the same basis and avoid counting a rebate twice.

Confirm eligibility before building the savings into your budget

For a typical new house or condo purchased from a builder for long-term residential rental, the enhanced rebate’s timing requirements generally include:

• Construction beginning between April 1, 2026, and March 31, 2027, inclusive; or construction beginning earlier, with the purchase agreement entered into during that window.

• Construction being substantially completed by December 31, 2029.

• HST becoming payable by December 31, 2032.

Other requirements apply, including existing rental rebate eligibility and a fair market value below $1.85 million. Assignment purchases and early sales require particular attention. Signing an agreement within the window does not, by itself, establish eligibility. CRA eligibility requirements

Have your lawyer or tax professional confirm how the rules apply to the specific property and purchase agreement before you rely on the projected savings.

Does the investment work while you wait?

HST relief can reduce your acquisition cost and free up capital once received. A sound investment still needs realistic rental income and a complete expense budget.

When reviewing an opportunity with you, I want to account for mortgage payments, property taxes, insurance, condo fees where applicable, maintenance, vacancy and the cost of financing any anticipated rebate. Run the numbers twice: during the waiting period and after the relief arrives. That gives you a clearer picture of both your cash requirements and the property’s longer-term performance.

Thinking about adding a new build to your portfolio? Let’s review the purchase price, cash needed to close and projected rental income together, so you can make an informed decision about your next investment.
