Most real estate investors hit a wall after buying just a few rental properties. Your bank tells you you’re maxed out. Your mortgage broker says you’ve reached your limit. But here’s the truth: you can buy way more properties than you think.
A note on “unlimited”: In this article, “unlimited” means beyond the caps most big banks impose — typically 4-5 financed rentals. It does not mean mortgage approval is unlimited. It means we work with lenders that scale past traditional caps. Lender qualification still applies at every step; no investor gets “unlimited” approval.
The secret isn’t finding more money or boosting your income. It’s understanding how to work with different types of lenders in the right order.
Why Most Investors Get Stuck
Financing is the biggest challenge in building a rental property portfolio. Not finding deals. Not property management. Financing.
Here’s what typically happens: You buy a few properties through your bank. Everything seems fine. Then suddenly, they tell you they can’t approve another mortgage. You assume you’re done. But there are ways to qualify for multiple rental properties that most investors never learn about.
But you’re not. You just need to know where to go next.
The Four Types of Lenders You Need to Know
A Lenders: Your Starting Point
Rate ranges below are as of April 2026 and shift with the market.
A lenders are the big banks, credit unions, and trust companies. They offer the best rates and terms, but they have strict rules:
- They only count 50% of your rental income when calculating your debt ratios
- They cap how many rental properties you can own (usually 5-12 depending on the lender)
- You need to fit within a 44% debt-to-income ratio
Here’s the problem with that 50% rule: Let’s say your property rents for $2,000 per month. Your mortgage and taxes are $1,500. You’re making $500 profit each month. But the bank only counts $1,000 of that rental income. So on paper, they see a $500 loss. This fake loss eats away at your ability to qualify for more mortgages.
B Lenders: More Flexibility, Higher Costs
B lenders work with borrowers who don’t fit the traditional lending box. Their rates typically run 1–2% higher than A lender rates, plus fees of 1% to 1.5% of your mortgage amount.
The big advantage? They’ll accept debt ratios up to 70% instead of the standard 44%. That’s a huge difference in borrowing power.
Commercial Lenders: The Hidden Gem
This is where things get interesting. Most people think commercial mortgages are only for apartment buildings or shopping malls. Wrong.
You can get commercial mortgages on residential rentals on single-family homes. And here’s why they’re powerful:
- Rates typically in the 6–8% range, competitive with or below B lender pricing
- They qualify you based on the property’s Cash Flow, not your personal income
- No stress test in many cases
- Lower down payment requirements
One real example: A fourplex worth $800,000 required a $320,000 down payment (40%) at a traditional bank. Through a commercial lender, the same property only needed $200,000 down (25%). That’s $120,000 in savings right there.
Commercial lenders use something called a Debt Service Ratio. They compare the rental income to the property expenses. Some want to see 1.3 (meaning 30% positive cash flow). Others accept 1.0 (break-even). Either way, your personal income matters way less.
Private Lenders and MICs: Your Last Resort
Private lenders and Mortgage Investment Corporations (MICs) charge the highest rates. Individual private lenders charge 10-12%. MICs charge 5-8%. Both charge fees between 1.5% and 3%.
MICs are better than individual private lenders because they’re stable corporations with millions in funds. Individual private lenders sometimes use personal lines of credit and might need their money back suddenly if they get divorced or lose their job.
You want to avoid this category as much as possible. But knowing it exists means you always have options.
If you didn’t know that commercial lenders can finance single-family rentals based on property cash flow — often at competitive rates below B lender pricing — there’s more to uncover. Book a free strategy call with LendCity and we’ll map out your lender sequence.

The Order Matters More Than Anything
Here’s the mistake that costs investors millions of dollars: going to lenders in the wrong order.
Some A lenders cap you at 5 properties total, no matter where your mortgages are. Other A lenders let you have 5 properties with them specifically, even if you own 10 properties financed elsewhere.
If you go to the flexible lender first, you waste that opportunity. Once you have 5 properties total, the strict lender will reject you. But if you go to the strict lender first, you can still use the flexible lender later.
- Start with A lenders that have absolute property caps
- Move to A lenders that count properties with them only
- Switch to specialized A lenders using 80-100% of rental income
- Transition to commercial lenders
- Use B lenders if needed
- Use private lenders or MICs as a last resort
The Specialized A Lenders Most People Don’t Know About
Not all A lenders are created equal. Some specialize in working with investors and offer way better terms:
- They use 80% to 100% of your rental income (not just 50%)
- They allow 10-12 properties instead of 5
- They don’t require you to keep $100,000 sitting in the bank doing nothing
These lenders have the same great rates as traditional banks. But they actually understand how rental properties work. Exploring all your residential mortgage financing options can double or triple your portfolio size before you need to move to other lender types.

Why Most Brokers Get This Wrong
Most mortgage brokers aren’t investment property specialists. When you max out with one or two A lenders, they send you straight to B lenders or private lenders because it’s easier.
They skip right over commercial options. They don’t know about the specialized A lenders. They cost you thousands of dollars in unnecessary interest and fees.
You need someone who knows the difference between lenders, understands the strategic order, and has relationships with Canadian commercial lenders who actually work with investors.
How Commercial Lending Changes Everything
When you shift to commercial lending, the whole game changes. Instead of asking about your job and income, they ask about the property.
Does it cash flow? What’s the debt coverage ratio? That’s basically it. This approach of qualifying for mortgages based on property cash flow is a game-changer for scaling.
This means you can keep buying properties even after you’ve personally maxed out on income qualification. The properties qualify themselves.
And don’t make the mistake of just walking into your bank’s commercial department. Different commercial lenders have wildly different requirements. Some require 1.3 debt coverage. Others accept 1.0. Some use stress tests. Others don’t. Some want 40% down. Others accept 25%.
The Real Strategy for Unlimited Properties
Here’s what “unlimited” actually means in this article: you’re not limited by the caps a single big-bank lender imposes. You’re limited by deal quality, down payments, and lender qualification at every step — no investor gets “unlimited” approval. The strategies here describe financing structures that allow scaling beyond traditional limits.
By working through all four lender types strategically, some investors build portfolios of 20, 30, or 50+ rental properties over many years. Each lender type gives you another batch of properties before you need to level up. Individual results vary with income, market conditions, property selection, and lender appetite.
The key is having a roadmap. Know which lender you’ll use for property number 6 before you buy property number 5. Have a plan for what happens when you max out traditional financing.
Stop accepting “you’re maxed out” as the final answer. It’s just the end of one chapter. Three more chapters are waiting.

Cash Flow
The money left over after collecting rent and paying all expenses including mortgage, taxes, insurance, maintenance, and property management. Positive cash flow is the primary goal of buy-and-hold investors. See also [NOI](/glossary/noi), [Cash-on-Cash Return](/glossary/cash-on-cash-return), and [Vacancy Rate](/glossary/vacancy-rate).
Commercial Mortgage
Financing for commercial properties like retail, office, or multifamily buildings with 5+ units, with different qualification criteria than residential mortgages.
Down Payment
The upfront cash payment when purchasing a property. For 1-4 unit investment properties, minimum 20% down is required. 5+ unit multifamily can use CMHC MLI Select with lower down payments, and house hackers can put as little as 5% down on owner-occupied 2-4 plexes. Your down payment directly affects your [LTV](/glossary/ltv) and the amount of [leverage](/glossary/leverage) you use.
Single Family
A detached home designed for one household, the most common property type for beginner real estate investors.
B Lender
Alternative lenders that serve borrowers who don't qualify with major banks, offering slightly higher rates with more flexible criteria.
Private Mortgage
A mortgage from a private lender rather than a traditional bank, typically with higher rates but more flexible qualification requirements.
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.
Blanket Mortgage
A single mortgage that covers multiple properties, often used by investors to simplify financing for a portfolio. Allows release of individual properties as they're sold.
Mortgage Stress Test
A federal requirement to qualify at the higher of your contract rate +2% or the benchmark rate (around 5.25%). For investors, rental income can be used to offset this calculation, though lenders typically only count 50-80% of expected rent.
Coverage Ratio
A measure of a property's ability to cover its debt payments, typically referring to DSCR. Commercial lenders often require a minimum of 1.2, meaning the property's net operating income exceeds debt payments by at least 20%.
Commercial Lending
Financing for commercial real estate or business purposes, typically qualified based on property income (NOI) rather than personal income. Includes mortgages for multifamily buildings (5+ units), retail, office, and industrial properties.
