If you own rental properties right now, there’s a good chance you’re dealing with something that shouldn’t be happening – negative cash flow. Your properties should be making you money, not costing you money every month.
Here’s what happened: A lot of investors chose variable rate mortgages because they made sense. Lower rates, easy to exit if needed, and you could pay them down faster if you wanted. But when rates shot up, those same mortgages became a problem. Now investors are calling every day asking about selling their properties because they can’t afford to keep them anymore.
The good news? You don’t have to sell. There are three solid strategies that can flip your situation from negative to positive cash flow. Let me walk you through each one.
Strategy 1: Switch to Interest-Only Payments
This one surprises a lot of people, but it works really well for serious investors. You can convert your current mortgage into an interest-only mortgage or line of credit.
Now, I know what you’re thinking – doesn’t interest-only mean a higher rate? Yes, it does. But here’s the thing: you’re not paying any principal anymore. That chunk of money that was going toward paying down your mortgage? It stays in your pocket instead.
When you do the math, your monthly payments drop significantly. Even with the slightly higher rate, you end up paying less each month. And that’s exactly what you need when cash flow is tight.
Why Real Investors Like This Option
If you’re building a real portfolio, you probably aren’t trying to pay off your mortgages anyway. That money sitting in home equity doesn’t do anything for you – investors call it “dead equity.” You want your money working, earning more money through Appreciation and cash flow.
One more bonus: if you get the line of credit version, you can convert it back to a regular mortgage later if rates drop or your situation changes. You’re not locked in forever.
Keep in mind, this option depends on where your properties are located, your overall debt ratios, and your credit score. Not everyone qualifies, but it’s worth checking.
Strategy 2: Change Lenders and Extend Your Amortization
This strategy is simple but powerful. Instead of staying with your current lender and locking in your variable rate, you switch to a different lender.
Why does this matter? Because when you stay with your current lender, they lock you into whatever Amortization you have left. If you started with 30 years and you’ve been paying for 7 years, they’ll give you 23 years. That’s it.
But when you move to a new lender, you can get a fresh 30-year amortization. Same rate (or sometimes even better), but way lower monthly payments.
Here’s a Real Example
Let’s say your current lender offers you 5.2% if you lock in your variable rate. Sounds okay, but you’re stuck with that shorter amortization and higher payments.
Now imagine switching to a new lender at that same 5.2% rate. The rate is identical, but you get 30 years instead of 23. Your monthly payment drops, and suddenly your cash flow improves.
This strategy works especially well if you’ve been on a variable rate for a while and your amortization has gotten shorter. Adding those years back gives you breathing room.
Switching to a new lender for a fresh 30-year amortization at the same rate could be the simplest fix for your cash flow — book a free strategy call with LendCity and we will check what terms you qualify for.
Strategy 3: Add a Second Suite or Renovate
This one requires more work upfront, but it can completely transform your property’s performance. You refinance your mortgage, pull out some equity, and use that money to add a second rental unit.
Yes, your mortgage payment goes up when you take money out. But you’re also adding a whole new stream of rental income. If you do it right, that new income covers the increased payment and then some.
Important Steps Before You Start
Before you run out and start building, check with your local municipality. Make sure second suites are allowed in your area. Check the zoning rules. You don’t want to spend money on renovations only to find out you can’t legally rent the space.
If adding a full second suite isn’t possible, you can still use this strategy. Pull out equity and use it to renovate the property instead. Maybe the place needs updating, or there are repairs you’ve been putting off. A renovated property can command higher rent.
The key is making sure the numbers work. Will the rent increase cover your higher mortgage payment? If yes, then it makes sense. If no, then this might not be your best option.
Which Strategy is Right for You?
Each of these strategies works in different situations. Some investors use just one. Others combine two or even all three approaches across different properties.
The interest-only option works great if you need immediate payment relief and you’re focused on cash flow over everything else.
Switching lenders and extending your amortization makes sense if you want to keep things simple while lowering your payments.
Adding a second suite or renovating is the best choice if you’re willing to do some work upfront for a bigger payoff long-term.
Whether you combine interest-only payments with a second suite or just extend your amortization, the right strategy depends on your full portfolio picture — book a free strategy call with us so we can review your options together.
Don’t Give Up on Your Portfolio
Too many investors are ready to sell because they think they’re out of options. But selling in a tough market often means losing money. And if you’ve held these properties for years, you’re giving up all that future appreciation. If you’re facing a Made a Bad Investment? Here’s How to Recover, understanding your options can help you make rational decisions rather than emotional ones.
These three strategies have helped countless investors stay in the game. Instead of selling at a loss, they fixed their cash flow problems and kept building wealth.
If you’re struggling with negative cash flow right now, don’t wait until you’re completely underwater. The sooner you explore your options, the more choices you’ll have.

Amortization
The period over which a mortgage is scheduled to be fully paid off through regular payments of principal and interest. In Canada, common amortization periods are 25 or 30 years, though the mortgage term (when you renegotiate) is typically 1-5 years.
Appreciation
The increase in a property's value over time, which builds equity and wealth for the owner through market growth or forced improvements.
Cash Flow
The money left over after collecting rent and paying all expenses including mortgage, taxes, insurance, maintenance, and property management.
Credit Score
A numerical rating (300-900 in Canada) that represents your creditworthiness, affecting mortgage rates and approval. 680+ is typically needed for best rates.
Equity
The difference between a property's current market value and the remaining mortgage balance. If your home is worth $500,000 and you owe $300,000, you have $200,000 in equity. Equity builds through mortgage payments, appreciation, and property improvements.
Principal
The original amount of money borrowed on a mortgage, not including interest. Each mortgage payment includes both principal (paying down what you owe) and interest (the cost of borrowing). Over time, more of each payment goes toward principal as the loan balance decreases.
Refinance
Replacing an existing mortgage with a new one, typically to access equity, get a better rate, or change terms. Investors commonly refinance to pull out capital for purchasing additional properties (cash-out refinance) while retaining ownership of the original property.
Variable Rate Mortgage
A mortgage where the interest rate fluctuates with the prime rate, meaning your payments or amortization can change over time.
Mortgage Broker
A licensed professional who shops multiple lenders to find the best mortgage rates and terms for borrowers. Unlike banks, brokers have access to dozens of lending options.
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.
Zoning
Municipal regulations that dictate how properties in specific areas can be used, including residential, commercial, industrial, or mixed-use designations. Zoning bylaws affect what investors can do with properties, including rental restrictions, multi-unit conversions, and home-based businesses.
Rent Increase
The process of raising rental rates for existing or new tenants. In provinces with rent control, annual increases for existing tenants are capped at government-set guidelines, while new tenancies can often be set at market rates.
