If you are looking to get into real estate investing without draining your savings, there are more financing options than most people realize. The two most common are residential loans and commercial loans, and the difference between them is not a technicality. It changes your down payment, how you qualify, how long you have to repay, and what happens to your rate five years from now.
Here is how they actually work.
Residential Loans
A residential loan is the familiar one. It funds primary residences, and it is flexible enough to fund investment property too.
Many investors use residential loans for smaller properties of one to four units. The draw is the 30-year fixed structure. Payments are spread over three decades at a rate that does not move, which gives you room when something goes wrong. If your rental hits a vacancy stretch or needs a costly emergency repair, the monthly cash flow is usually there to absorb it without you writing a check from your own pocket.
The tradeoff is paperwork about you. Residential underwriting looks at your personal financial history in detail. Expect to hand over pay stubs, tax returns, asset statements, and more. The bank is assessing you first and the property second.
Commercial Loans
Commercial loans can finance rental property, an owner-occupied business property, or in some cases a personal home.
They also carry higher down payments, shorter terms, and rates that reset. So why would anyone choose one?
Usually because they have to. Here are the four situations that push an investor into commercial financing.
1. The property has five or more units
Residential loans are for properties with four units or fewer. Five units is commercial. This is a hard line, not a guideline.
2. You are buying in the name of an LLC
Buying under an LLC with residential financing creates real problems, particularly around quitclaiming, which is transferring ownership. Quitclaiming a residential loan into an LLC can trigger a due-on-sale clause, which means the bank can call the loan and demand the full balance. Your title insurance may not transfer either. With a commercial loan, the LLC is on the paper from day one, so there is nothing to transfer and nothing to trigger.
3. Your income does not fit the residential box
If you are self-employed, paying yourself in distributions, or otherwise short on the W-2 history residential underwriting wants, commercial can be the easier path. Commercial approval leans on what the property produces rather than what your pay stub says.
4. You have hit the financed-property limit
There is a ceiling on how many financed properties you can carry with residential financing. More on that next, because the way this rule works is widely misunderstood.
When You Outgrow Residential Financing
This is the question most investors are actually asking, so let us answer it directly.
The four-unit cliff. Residential financing stops at four units. Buy a five-unit building and you are in commercial territory, no exceptions.
The 10-property limit. Fannie Mae limits a borrower to 10 financed one-to-four-unit properties when the property being financed is a second home or an investment property.
Here is the part people get wrong, and it is worth understanding properly.
The count follows you, not your household. It counts every one-to-four-unit property you are personally obligated on, including your own home if it carries a mortgage. A property you own free and clear does not count, because nobody is obligated on it. And the count is added up across everyone on the application.
That last piece is what surprises people. A married couple applying together shares one limit of 10, not 10 apiece. The limit is not a marital allowance, and it does not key on whose name is on the deed. It keys on who signed the note.
Whether two spouses could each build toward their own 10 by applying separately depends entirely on whether each one qualifies alone, on their own income, their own credit, and their own reserves. That is a much harder test than it sounds, and it is the test that usually decides the answer. Reserve requirements also step up as your property count rises.
One more thing worth saying plainly: the agency limit is a ceiling, not an offer. Individual lenders set their own limits, often well below 10.
Past that line, residential financing is done and you are in commercial and portfolio territory. That is not a wall. It is a different conversation, and it is one worth having before you are under contract rather than after. We wrote more on financing limits for one-to-four-family rentals if you want the detail.
How They Differ
Some financial jargon is unavoidable here, so we will keep it plain.
Down Payment
Residential mortgages generally ask for less money down.
A conforming loan is one that meets Fannie Mae and Freddie Mac requirements and falls under the annual limit. For 2026, that limit is $832,750 for a one-unit home, and every Minnesota county sits at that baseline. The FHFA resets this number each November, so check the current year before you rely on it.
Down payment minimums on conforming loans start at 3%. That 3% used to be first-time-buyer territory only, and it is not anymore. Programs like HomeReady and Home Possible reach 3% down for moderate-income buyers who have owned before. A 5% down conventional loan remains the common path for buyers who do not fit those programs. If you put less than 20% down on a residence, expect Private Mortgage Insurance. The good news is that it is not permanent: on a conventional loan you can request cancellation at 80% loan-to-value, and it terminates automatically at 78%.
Commercial real estate is simpler and more expensive. Plan on roughly 20% down as a starting point. If you want specific terms, such as cash out at closing, your lender may look for more. There is no mortgage insurance on the commercial side. The lender manages that risk through the loan-to-value and the guaranty structure instead.
Qualifications
This is the real dividing line.
Residential underwriting qualifies you. Your income, your credit, your history.
Commercial underwriting qualifies the property. The more income the building produces, the less your personal financials drive the decision. Understanding the underwriting process and knowing what to bring is often the difference between an approval and a maybe. Our commercial loan applicant checklist lays out exactly what to have ready, and there is more in our guide to getting approved for a commercial real estate loan.
Where the Loan Comes From
You can get a residential loan almost anywhere: a national lender, an online shop, a broker.
Commercial real estate loans usually come from community banks. Ideally one that already knows you, because commercial underwriting has judgment in it, and judgment goes better when the lender knows your history and your market. You can see how we structure commercial financing in Minnesota including real estate, equipment, and SBA options.
Rate Structure
This is the difference most people miss, and it matters more than the rate itself.
A residential mortgage is typically fixed for the full 30 years. The rate you sign is the rate you keep.
A commercial real estate loan is typically fixed for a term, then repriced. A common community bank structure is a rate fixed for five years on a 20 to 25 year amortization schedule, with a reset or a balloon at the end of that fixed period. The rate you get at closing is not the rate you keep for the life of the loan.
That is worth planning around. Truly floating rates, the kind that move with an index every month, are normal for lines of credit and construction loans, not for stabilized commercial term debt.
Amortization Period
Amortization is the schedule that pays the loan down. Residential loans typically amortize over 15 or 30 years. Commercial loans on 1-4 family rentals amortize over 20-25 years and commercial real estate over 15-20 years on average, which means higher monthly payments for the same borrowed amount.
Which Loan Is Right for You?
There is no clean answer to this in the abstract, and any article that gives you one is guessing about your situation.
What we can tell you is that the decision usually turns on three things: how many units, how many properties you already carry, and whether your income tells the story your tax returns tell. If you are near the four-unit line or the ten-property line, that is the moment to have the conversation, not after you are under contract.
Our lenders know Minnesota real estate and they know what makes an investment work here. If you are building a real estate investment plan, or you are just trying to figure out which side of the line your next deal falls on, we should talk.

Frequently Asked Questions
What is the main difference between a residential and a commercial loan?
Residential loans finance properties with one to four units and qualify you based on your personal income and credit. Commercial loans finance five or more units, or property held in a business entity, and qualify based on what the property produces.
How many residential loans can one person have?
Fannie Mae limits a borrower to 10 financed one-to-four-unit properties for second homes and investment properties. The count is cumulative across all borrowers on the application, so a couple applying jointly shares one limit of 10 rather than getting 10 each.
Can a married couple each finance 10 properties?
The limit follows the borrower, not the marriage. It counts the properties you are personally obligated on, added together across everyone on the application. A couple applying together shares one limit of 10. Whether each spouse could build toward their own 10 separately comes down to whether each qualifies alone, on their own income, credit, and reserves, without the other on the note. That is a harder test than most people expect, and it is worth walking through with a lender before you plan around it.
Can I buy a rental property in an LLC with a residential loan?
It is generally a bad idea. Transferring a residentially financed property into an LLC can trigger a due-on-sale clause and can disrupt title insurance. A commercial loan puts the LLC on the paperwork from the beginning.
Do commercial real estate loans have fixed or variable rates?
Most community bank commercial real estate loans are fixed for a term, commonly five years, on a longer amortization schedule, and then reprice. That is different from a 30-year fixed residential mortgage, where the rate never changes.
What is the conforming loan limit in Minnesota for 2026?
$832,750 for a one-unit property. Every Minnesota county is at that baseline. The FHFA resets the limit each November.
