The “You’re Maxed Out” Problem Every Investor Faces

Here’s a story I see play out all the time.

An investor comes to me frustrated. They’ve got a solid portfolio. Cash flow is good. Properties are performing. But when they went to their bank for another rental property — or even just a credit card — they got shot down.

“Your debt ratios are too high.”

Sound familiar?

Here’s the thing: that investor wasn’t actually maxed out. The bank was just calculating their rental income wrong. And this happens constantly because most lenders — and honestly, most mortgage brokers — don’t know how to properly account for rental income.

The solution? Rental worksheets. And if you’re not using them, you’re leaving money (and deals) on the table.

Why Banks Think You’re Losing Money (When You’re Not)

Let me break this down with real numbers because this is where it gets frustrating.

Say you’ve got a rental property:

• Rent: $3,000/month
• Mortgage payment: $2,000/month
• Property taxes: $200/month
• Total expenses: $2,200/month

In the real world, you’re cash flowing $800 a month. Nice, right?

But here’s how most lenders see it. They only count 50% of your rental income. So instead of $3,000, they’re using $1,500.

Now do the math: $1,500 income minus $2,200 expenses = negative $700 per month.

According to the bank, you’re LOSING $700 a month on a property that’s actually making you $800. That’s a $1,500 swing in the wrong direction — and it’s completely artificial.

Multiply that across three, four, or five properties? Your debt ratios look terrible on paper, even though your actual cash flow is great.

How Rental Worksheets Change Everything

Rental worksheets are specialized calculation tools that allow certain lenders to use almost 100% of your rental income instead of just 50%.

Here’s how it works:

Instead of the standard rental offset calculation, the lender takes your entire portfolio and runs it through their rental worksheet. They input 100% of the rent, apply their own expense formulas, and if there’s a surplus — which there almost always is for well-bought properties — that surplus gets ADDED to your income.

It’s like erasing all your rental properties from the liability side and moving the cash flow to the income side.

The result? Dramatically higher buying power.

I had a client recently who couldn’t get approved for a $10,000 credit card because of “debt ratios.” But using a rental worksheet on his existing portfolio, we got him approved for a full mortgage on his next investment property. The mortgage was easy. The credit card was hard. Think about how backwards that is.

That’s the power of this tool.

Why Most Brokers Don’t Use Rental Worksheets

Here’s the honest truth: rental worksheets take work.

Every lender has their own version. There’s no universal form. Each one has a slightly different formula, different expense assumptions, different ways of calculating the numbers.

Some lenders’ worksheets work better than others. Some will give you more buying power for the same portfolio. Finding the right match takes time and experience.

Most brokers don’t bother. They submit the application the standard way, get a decline or a tough approval, and tell the client they’re maxed out.

But if you’re working with a broker who specializes in investment properties, they’ll know which lenders have the best rental worksheets and how to maximize your numbers. If you’ve been told your debt ratios are too high, talk to a LendCity mortgage professional who actually knows how to run these calculations properly.

The “Too Many Properties” Myth

While we’re at it, let’s tackle the other common rejection: “You have too many properties.”

Most banks have a limit of five financed properties. But here’s what they don’t tell you:

• Some banks count five properties TOTAL, even if the mortgages are elsewhere
• Other banks allow five properties WITH THEM, regardless of what you have elsewhere
• Some lenders specialize in portfolio investors and don’t have these limits at all

So when a bank says you have too many properties, what they really mean is: “We don’t know how to work with investors like you.”

The right broker knows which lenders to match you with based on your current portfolio size and where you want to go.

What This Means For Your Next Deal

If you’re an investor — or you work with investors — here’s what you need to know:

Don’t accept “maxed out” as final. Get a second opinion from someone who actually specializes in investment mortgages.

Ask about rental worksheets. If your broker doesn’t know what you’re talking about, find one who does.

Shop lenders strategically. The best lender for your portfolio depends on how many properties you have, where your current mortgages are, and what your rental income looks like.

Get your numbers ready. Rental worksheets require detailed information on every property — rents, expenses, mortgage balances, everything. The more organized you are, the faster you’ll get approved.

Here’s my advice: before you start shopping for your next property, book a free strategy call with LendCity to see exactly how much buying power you actually have. You might be surprised.

The Bottom Line

The banks aren’t trying to screw you over. They just have rigid systems designed for typical homeowners, not investors.

Rental worksheets are the workaround. They let you show your real financial picture instead of the artificially deflated version that standard calculations create.

If you’re serious about building a portfolio, you need a mortgage professional who knows these tools inside and out. It’s the difference between buying one more property and buying five.

Key Terms in This Article

Rental Worksheet

Rental Worksheet

A Rental Worksheet is a standardized form used by Canadian lenders to calculate the net rental income from an investment property, typically accounting for a vacancy allowance and operating expenses to determine how much rental revenue qualifies toward mortgage approval. This document helps investors demonstrate their property's cash flow when applying for financing on rental properties.

Debt Ratios

Debt Ratios

Debt ratios are financial calculations lenders use to determine how much of your income goes toward debt payments, with the two main types being Gross Debt Service (GDS) and Total Debt Service (TDS) ratios. For Canadian real estate investors, these ratios are critical qualifying factors that determine borrowing capacity, with most lenders requiring GDS below 39% and TDS below 44%, though rental income from investment properties can help offset these calculations.

Rental Income

Rental Income

Revenue generated from tenants paying rent on an investment property. Gross rental income is the total collected before expenses, while net rental income subtracts operating costs to show actual profitability.

Cash Flow

Cash Flow

The money left over after collecting rent and paying all expenses including mortgage, taxes, insurance, maintenance, and property management.

Buying Power

Buying Power

Buying power refers to the maximum property value or mortgage amount a real estate investor can qualify for based on their income, credit score, existing debts, and available down payment. For Canadian investors, this determines how much property they can acquire and is directly affected by current interest rates, lending guidelines from OSFI, and stress test requirements.

Portfolio Investor

Portfolio Investor

A portfolio investor is a lender, often a credit union or private institution, that funds mortgages using their own capital and keeps the loans on their books rather than selling them to insurers like CMHC. For Canadian real estate investors, portfolio lenders are valuable because they often have more flexible qualification criteria and can approve deals that traditional banks following strict insurer guidelines would decline.

Mortgage Qualification

Mortgage Qualification

Mortgage qualification is the process where a lender evaluates an investor's income, credit score, debt ratios, and financial assets to determine their eligibility for a mortgage and the maximum loan amount they can receive. For Canadian real estate investors, this includes passing the federal stress test at a qualifying rate typically 2% above the contract rate, which directly impacts purchasing power and investment strategy.
