How Do Mortgage Investors Actually Make Money?

Investors weighing a mortgage investment usually see one number first: a rate. Behind that number is a chain of payments that starts with a borrower and ends, after several deductions, with the investor. Knowing how mortgage investors make money means knowing each link in that chain, because the gap between what borrowers pay and what investors keep is where most misunderstandings start.

This guide sets out where mortgage investment income comes from, what is taken out before it reaches the investor, how a mortgage investment corporation (MIC) passes it on, and how it is taxed.

How do mortgage investors make money?

Mortgage investors make money from what borrowers pay for the use of their money: mainly interest, plus fees. Four sources make up the gross income of a mortgage or a mortgage pool.

• Interest. The borrower pays a rate on the outstanding principal, usually monthly and, in private lending, often interest-only.
• Lender fees. A fee charged to the borrower when a loan is funded, and sometimes when it is renewed or extended.
• Other borrower charges. Late-payment charges, default interest or fees for dishonoured payments, where the loan documents allow them. Some of these go to the mortgage administrator rather than to investors.
• Leverage, in some pools. A MIC or fund that borrows money to lend at a higher rate earns the difference. Subsection 130.1(6) of the Income Tax Act caps a MIC’s liabilities at three or five times its equity, depending on its asset mix, and leverage magnifies losses as well as income.

What is not on the list matters too. A lender does not share in rising property values; that gain belongs to the owner. Mortgage investment income is contractual income, capped by the loan terms, and it depends on borrowers continuing to pay.

Mortgage interest income: the main source

Interest is the bulk of mortgage interest income in almost every structure. On an interest-only loan, annual interest is the principal multiplied by the rate: a $300,000 loan at an assumed 9% produces $27,000 a year, or $2,250 a month, with the $300,000 itself due at maturity.

The rate a borrower pays reflects the risk the lender takes: the borrower’s credit and income, the property, the loan-to-value, the position on title, the term and the region. Higher yield comes with higher risk. A loan priced well above bank rates is priced that way because the chance of a late payment, a default or a loss is higher. Interest that accrues but is not paid is not income in hand; on a defaulted loan, it is recovered from the sale of the property only if the proceeds stretch that far.

Lender fees, and who keeps them

A lender fee is a charge the borrower pays to the lender, usually at funding and often deducted from the amount advanced. On short loans it can be a meaningful share of total income, because it is earned once on a loan that may last only months.

Who keeps the fee depends on the structure. In a mortgage held directly, it belongs to the investor. In a pooled vehicle, the offering memorandum states whether lender fees are income of the pool or are retained by the manager or a related company. The mortgage broker’s fee, also paid by the borrower, goes to the broker and is not investor income. The real fee stack in a mortgage investment itemises who is paid what.

What comes out before the investor is paid

Every structure takes costs out of gross income before the investor receives anything, and the size of those deductions is the difference between a loan rate and an investor’s return. The main ones are:

• Mortgage administration: collecting payments, holding them in trust, chasing arrears and handling renewals.
• Management fees, and any performance fee, in a MIC or fund.
• Operating costs: audit, legal, trustee and dealer costs.
• Credit losses: principal not recovered after a default, plus enforcement costs such as legal fees and selling costs.
• Cash drag: money waiting to be lent, or held back to meet redemptions, which earns little or nothing.
• Borrowing costs, where the pool uses leverage.

The result is three different numbers: the gross yield the loans earn, the net yield after costs and losses, and the after-tax yield the investor keeps. Gross, net and after-tax yield explains each.

Worked example (illustrative)

Assume a mortgage pool with $10,000,000 lent out for a full year, no borrowing, and no change in the number of shares. Every figure is an assumption chosen for round arithmetic, not a forecast or a typical result.

1. Interest: an average rate of 10% on $10,000,000 = $1,000,000.
2. Lender fees kept by the pool: $100,000. Gross income: $1,000,000 + $100,000 = $1,100,000, or 11% of the portfolio.
3. Management fee: 2% of $10,000,000 = $200,000.
4. Operating costs (audit, legal, administration): $50,000.
5. Credit losses: 1% of the portfolio = $100,000.
6. Net income: $1,100,000 − $200,000 − $50,000 − $100,000 = $750,000, or 7.5% of the portfolio.
7. An investor holding $50,000 of shares (0.5% of the pool) receives $750,000 × 0.5% = $3,750 before tax.
8. Tax at an assumed 40% marginal rate: $3,750 × 40% = $1,500, leaving $2,250, or 4.5% of the $50,000.

Now change one assumption. If credit losses were 3% ($300,000) instead of 1%, net income would fall to $1,100,000 − $200,000 − $50,000 − $300,000 = $550,000, or 5.5%, and the investor’s pre-tax share to $2,750. Borrowers paid the same rates in both cases; the investor’s income moved because losses did.

How a MIC turns mortgage interest into investor income

A MIC collects the interest and fees on its loans, pays its costs, and distributes its taxable income to shareholders instead of paying corporate tax on it. Under subsection 130.1(2) of the Income Tax Act, those taxable dividends (other than capital gains dividends) are deemed received by the shareholder as interest.

Distributions are paid on the schedule the offering memorandum sets, commonly monthly or quarterly; Lendmax Capital MIC, for example, pays quarterly, in cash or reinvested through a distribution reinvestment plan (DRIP). The timing of cash flow and the choice between taking and reinvesting income are covered in monthly income from mortgage investments. Distributions are declared from income actually earned, so they can be reduced or suspended when borrowers stop paying.

What is a realistic return on a mortgage investment?

A realistic return is the net rate a given investment has actually paid, over a stated period, judged against the risk taken to earn it. No general figure applies, because returns vary with the position, loan-to-value, borrowers, terms, fees, losses and leverage of each loan or pool.

Four questions make any quoted figure readable. Is it gross, net of fees and losses, or after tax? Over which period, and is it a full year or annualised from a shorter one? Was it paid, or is it a target? Is it audited? Lendmax Capital MIC, for example, publishes the net rate of return it has paid investors for each fiscal year on its Past performance page, and this site’s performance and risk overview explains how its portfolio is managed for risk. Past performance does not indicate future results. Mortgage investments are not guaranteed, returns are targets, not promises, and principal can be lost. They are also not deposits: CDIC insures eligible deposits at member institutions up to $100,000 per insured category, and mortgage investments carry no CDIC or provincial deposit insurance.

What reduces or stops mortgage investment income?

The same features that produce the income can interrupt it, and investors see the effect as lower or delayed payments, or a lower share value.

• Arrears and default: a borrower who stops paying stops the interest on that loan, and enforcement adds costs.
• Early repayment: a loan repaid early leaves cash waiting to be relent, possibly at a lower rate.
• Falling market rates: new loans and renewals are priced lower.
• Redemption demand: a pool that holds cash to pay departing investors earns less on it.
• Losses: principal written off reduces income and can reduce the value of the shares.

How is mortgage investment income taxed?

As at October 2026, mortgage investment income is generally taxed as interest at the investor’s full marginal rate. Interest from a mortgage held directly is reported as interest income; MIC dividends are deemed interest under subsection 130.1(2), reported on a T5 slip, with no dividend gross-up or tax credit. Held in a registered plan such as an RRSP or TFSA, the income is sheltered by the plan’s rules, provided the investment is qualified and not a prohibited investment for that plan holder. The after-tax yield calculator shows the effect of a marginal rate on a net yield; a Canadian tax professional can confirm the treatment for a particular investor.

Common mistakes when reading mortgage returns

• Comparing a loan rate with a fund’s net return. One is before costs and losses; the other is after.
• Reading a target as a promise. A target is what the manager is aiming for, not what will be paid.
• Ignoring the tax character. Income taxed as interest generally keeps less after tax than the same yield taxed as eligible dividends or capital gains.
• Watching distributions but not losses. Steady payments can coexist with write-downs that reduce the value of the investment.

What this means for a mortgage investor

Mortgage investors make money from borrowers’ interest and fees, and keep what is left after administration, management, losses and tax. The size of each deduction, and the risk of the income stopping, depends on seven axes: the borrower, the property, the loan-to-value, the security position, the term, the jurisdiction and the investment structure. Reading a return with all seven in view, and with its period and source, is what turns a rate into a figure an investor can judge. This is general education, not investment, tax or legal advice.
