Two different limits govern how far a Minnesota rental portfolio can grow on conventional financing. One caps the dollars on any single property. The other caps how many properties you can finance at all. Most investors learn about the second one the hard way, on the deal where it finally bites.
| $832,750 2026 conforming loan limit on a one-unit property |
| 10 Maximum financed properties under Fannie Mae guidelines |
| 87 of 87 Minnesota counties at the baseline limit. None is high-cost. |
If you own two rentals and you are shopping for a third, none of this is in your way yet. If you own six, it is the whole conversation. Knowing which limit you are approaching, and roughly when, is what lets you plan an acquisition instead of reacting to a decline.
When investors say a bank hit them with a "financing limit," they usually mean one of two very different rules.
The conforming loan limit is a dollar ceiling on a single mortgage. It is set each year by the Federal Housing Finance Agency, it changes every January 1, and it varies by how many units the property has. Go above it and the loan is no longer conforming, which does not mean it cannot be done. It means it is a different kind of loan.
The financed property limit is a count. It caps how many financed residential properties one borrower can hold and still qualify under agency guidelines. It has nothing to do with the size of any individual loan, and it is the one that quietly stops portfolios.
You can be well under the dollar limit on every property you own and still be shut out by the count. That surprises people, and it is the single most useful thing to understand before you write your next offer.
The Federal Housing Finance Agency announced the 2026 values on November 25, 2025, and they apply to mortgages Fannie Mae and Freddie Mac acquire during 2026. The baseline one-unit limit rose 3.26 percent over 2025, tracking the average increase in house prices between the third quarters of 2024 and 2025.
| Property type | 2026 baseline limit | Applies in Minnesota? |
|---|---|---|
| One unit | $832,750 | Yes, all 87 counties |
| Two units | $1,066,250 | Yes, all 87 counties |
| Three units | $1,288,800 | Yes, all 87 counties |
| Four units | $1,601,750 | Yes, all 87 counties |
Figures from the Federal Housing Finance Agency's 2026 county loan limit file.
Some parts of the country get higher limits because they are designated high-cost areas, where the ceiling runs to $1,249,125 on a one-unit property.
No Minnesota county carries a high-cost designation for 2026. All 87 sit at the baseline, from Hennepin to McLeod to Cook. A Twin Cities duplex gets no more room than one in Glencoe.
So the limit does not turn on which county you are buying in. It turns on how many units the building has. Notice how much the unit count moves the number: a four-unit building carries nearly double the ceiling of a single-family rental. Investors who feel boxed in on price sometimes find the answer is not a bigger loan on a house. It is a different building.
This is the one that ends conventional financing for growing investors, and it is widely misdescribed. Fannie Mae and Freddie Mac are two separate companies with two separate rulebooks. They do not share a single number, and treating them as one rule is how investors end up planning against a limit that does not apply to their loan.
Under Fannie Mae's selling guide, a borrower financing a second home or an investment property may have a maximum of 10 financed properties. The counting rules matter as much as the number:
That last rule catches people. Two investors who each own five properties and then apply together are at ten before they buy anything.
Freddie Mac sets its own requirements for borrowers who own or are obligated on multiple financed one-to-four-unit properties, in Guide Section 4201.13, and the terms tighten as the count rises. The practical point is that Freddie's answer is not automatically Fannie's answer. Before you assume you have room, ask your lender which agency's guidelines the specific loan is being underwritten to.
Long before you reach any hard cap, the terms get tighter. Agency guidelines layer on requirements as the number of financed properties rises, and the practical effects show up in three places.
| What tightens | What it means in practice |
|---|---|
| Down payment | Under agency guidelines, additional investment properties commonly require 25 percent down or more, well above what the same borrower put down on their first rental. |
| Reserves | Documented cash covering several months of payments, scaling with how many properties you hold. This is the one that most often turns a qualified buyer into a waiting buyer. The income supports the deal; the cash on hand does not. |
| Refinancing room | Options narrow as the portfolio grows. If your plan depends on pulling equity out of property four to buy property five, and that refinance is not available, the plan stalls in a way that is hard to see coming. |
None of this makes agency financing a bad tool. For a first or second rental it often fits well: long terms, straightforward qualification, and a process that looks similar from one lender to the next. The thing to watch is that it is not designed to scale with you.
A portfolio loan is one the bank keeps on its own books rather than selling it to Fannie Mae or Freddie Mac. Because the bank holds the risk, it also sets the terms, and agency property counts stop being the binding constraint.
That is the structural difference, and it is worth being precise about what it does and does not mean. It does not mean the underwriting is looser. It means the questions change. Instead of asking whether you fit a national template, the conversation is about this property, this rent roll, this borrower and this market.
This is the question investors ask most once the agency count is in view, and it deserves a direct answer rather than a brochure one. Requirements vary by lender and by deal. What follows is what a community bank portfolio lender typically looks at, and roughly where the bar sits.
| Requirement | What to expect |
|---|---|
| Property cash flow | The dominant test. Our commercial real estate lending generally looks for a debt service coverage ratio of 1.20 or higher on the property's net operating income. |
| Equity in the deal | As low as 20 percent down. Our loan policy allows an advance of up to 80 percent of the lesser of cost or appraised value on income-producing rental property. Where a deal lands inside that depends on the property and the borrower, but the requirement does not climb just because your property count does. |
| Term and structure | Amortization of 15, 20 or 25 years, with the interest rate adjusting every five years. We generally write the maturity to match the amortization rather than setting an earlier balloon date. Terms vary by deal. |
| Liquidity after closing | Cash left over once the deal closes, sized against the portfolio rather than the single property. This is where growing investors most often come up short. |
| Credit history | Reviewed, and it matters, but it carries less weight than it does on a consumer mortgage because the property is doing the work. There is no single cutoff to quote; it is read alongside everything else. |
| Experience | A track record of operating rentals carries weight here. Agency underwriting is built around a template and has less room to account for it. |
| Documentation | Two years of tax returns, a current rent roll, leases, a personal financial statement, and a schedule of real estate owned covering every property and its debt. |
Notice what the equity line is not indexed to: your property count. Agency guidelines tighten as that count rises, commonly to 25 percent down or more on later purchases. Our loan policy sets the advance rate at up to 80 percent of the lesser of cost or appraised value on income-producing rental property. Where a particular deal lands depends on the property and the borrower, but the number of rentals you already own is not what moves it.
One document tends to set the pace: the schedule of real estate owned. It lists every property you hold, what it is worth, what it owes, and what it earns. Investors who keep it current tend to move through underwriting quickly. Investors reconstructing it from memory can add weeks before anyone has looked at the new deal.
Every loan is underwritten on its own facts and is subject to credit approval. None of the above is a commitment to lend. It is what the conversation covers.
For income property, the ratio that usually decides the deal is the debt service coverage ratio, which compares a property's annual net operating income to its annual debt payments. Our commercial real estate lending generally looks for a debt service coverage ratio of 1.20 or higher, meaning the property produces about 20 percent more income than it needs to make its payments. That cushion is what absorbs a vacancy or a bad furnace year. Every deal is underwritten on its own facts and a ratio alone does not approve a loan, but if you are modeling a purchase, that is the number to model against.
We walk through the arithmetic in how much your property can borrow using debt service coverage, and our guide to commercial real estate underwriting covers how the rest of the file comes together.
One more structural question worth asking any portfolio lender: does the loan carry a balloon, or is the maturity written to match the amortization?
On this kind of property we generally write the maturity to match the amortization. A 20-year amortization would carry a 20-year maturity. The rate adjusts every five years, so you are still in the rate market, but the structure is not built around a maturity date that arrives while you still owe most of the balance.
Structure is not the whole story, and it is worth saying so plainly. Every loan carries covenants and conditions, and a loan agreement can be affected by things like a payment default or a covenant breach regardless of how the maturity is written. What the structure does is remove a scheduled event that would otherwise put your financing back in play on a date you did not choose. We walked through what that scheduled event costs, including the Minnesota mortgage registry tax paid again on each refinance, in balloon payment versus rate reset.
A rental property is not a national asset. A fourplex in Chaska and a fourplex in Cambridge have different rent ceilings, different vacancy behavior and different buyer pools. Someone underwriting the deal has to form a view on which of those applies, and local familiarity with the submarket is useful input into that view.
It is worth being plain about why this matters more on a rental than on a consumer mortgage. A house is underwritten mostly on the borrower. A rental is underwritten on the property, which means someone has to form a view on the local rental market. Whether that view is informed is the difference between a fast answer and a slow one.
Security Bank & Trust lends across 21 locations across Minnesota, from the western Twin Cities suburbs through the McLeod and Carver county communities and up into the Cambridge and Isanti area. If you are buying in one of those markets, you are talking to a lender who works in it.
At five units and above, a building is commercial multifamily and the one-to-four-family rules stop applying. No conforming loan limit, no financed property count. The deal is underwritten on the property's income and its operating history.
For investors who have run out of room on the residential side, this is often the more natural next step than fighting the count. A well-occupied small apartment building in Hutchinson or Chaska can be an easier file than an eighth single-family rental, because the income is the case and there is more of it in one place.
What changes in practice: the appraisal is an income appraisal rather than a comparable-sales one, the lender will want to see the leases and the operating history rather than just your tax returns, and the loan is a commercial structure with a periodic rate adjustment rather than a 30-year fixed rate. Our investment real estate financing guide covers how the commercial side is evaluated, and commercial real estate lending is a significant part of what we do across Minnesota.
Lenders are reading your operating record, not just the property. Three things make the file stronger.
Control the expense line. Net operating income drives the coverage ratio, so every dollar of avoidable expense reduces what you can borrow. Preventative maintenance costs less than emergency repair. Energy efficiency work lowers a recurring cost rather than a one-time one. And in multi-unit buildings, how utilities are billed matters: submetering bills each tenant for actual usage, while a ratio utility billing system allocates the total by a formula such as unit size or occupancy. Submetering is more precise and costs more to install. The allocation approach is simpler and less transparent to tenants.
Build the team before you need it. A property manager, an accountant who knows real estate, and an attorney for the lease and entity work. Add a banker to that list earlier than feels necessary. The time to meet a lender is not the week you have a purchase agreement and fourteen days to close.
Keep records a lender can read. Accounting and property management software matter less for the features than for what they produce: clean statements, a current rent roll, and a documented history. Underwriting tends to move at the speed of your documentation, so organized records are worth the effort they take to keep.
For 2026 the baseline conforming loan limit is $832,750 for a one-unit property, $1,066,250 for two units, $1,288,800 for three units and $1,601,750 for four units. All 87 Minnesota counties use these baseline figures. No county in Minnesota carries a high-cost designation for 2026, so the limits are the same statewide.
Under Fannie Mae guidelines a borrower may have a maximum of 10 financed properties when financing a second home or an investment property. Freddie Mac sets its own requirements separately in Guide Section 4201.13. The two are not the same rulebook, so the answer depends on which guidelines your specific loan is underwritten to. Beyond agency limits, portfolio lenders that keep loans on their own books are not bound by these counts.
Requirements vary by lender and by deal. At Security Bank & Trust, our loan policy allows an advance of up to 80 percent of the lesser of cost or appraised value on income-producing rental property, so as low as 20 percent down, and unlike agency financing that requirement does not rise as your property count does. Alongside the equity, we look at the property's cash flow, measured by a debt service coverage ratio our policy sets at a minimum of 1.20; the liquidity you retain after closing, sized against your whole portfolio rather than the one property; your credit history, which matters but carries less weight than on a consumer mortgage because the property is doing the work; your track record operating rentals; and documentation, meaning two years of tax returns, a current rent roll, leases, a personal financial statement, and a schedule of real estate owned. We generally structure these on a 15, 20 or 25 year amortization with the rate adjusting every five years and the maturity written to match the amortization rather than an earlier balloon date. Terms vary by deal, and every loan is underwritten on its own facts and is subject to credit approval.
Community banks and other portfolio lenders that hold loans on their own balance sheets, rather than selling them to Fannie Mae or Freddie Mac, are not bound by agency property counts. Security Bank & Trust is one of them. We finance 1-4 family rental property and commercial multifamily across 21 Minnesota locations spanning the western Twin Cities metro, McLeod and Carver counties, and the Cambridge and Isanti area. Because we hold these loans rather than selling them, the credit decision sits with the bank rather than with a secondary-market guideline.
Nothing happens to the loans you already have. The limit is a qualification rule for the next loan, not a covenant on existing ones. What happens is that the next agency loan is not available to you, and you finance the next purchase another way, most commonly through a portfolio lender that holds the loan on its own books.
A different thing entirely, and it is worth separating because the phrase looks similar. The 1-4 Family Rider is a document attached to a mortgage on a one-to-four-unit property that is being rented. It assigns the rents to the lender as additional security and covers related matters such as leases and the removal of certain fixtures. It is a document you sign at closing, not a limit on how much or how often you can borrow.
One. Under Fannie Mae's counting rules, a two-unit, three-unit or four-unit building counts as a single financed property. The count is of properties, not units and not mortgages.
Yes, if it is financed. Your primary residence is included in the count of financed properties. A borrower who owns a financed home and eight rentals is at nine, not eight.
The financed properties of all borrowers on the loan are added together. Properties you own jointly are counted once. Two partners who each separately own five properties are already at the limit before they buy anything together.
A portfolio loan is a mortgage the bank keeps on its own balance sheet instead of selling it into the secondary market. Because the bank holds the risk, it also sets the underwriting terms, so agency property-count limits do not apply. Terms are based on the property, the borrower and the market rather than a national template.
Our commercial real estate lending generally looks for a debt service coverage ratio of 1.20 or higher, meaning the property's net operating income is about 20 percent greater than its annual debt payments. Every loan is underwritten on its own facts, so a ratio by itself does not determine approval, but 1.20 is a reasonable figure to model against.
Yes. The Federal Housing Finance Agency sets the values annually and they take effect January 1. The 2026 values were announced November 25, 2025, and the one-unit baseline rose 3.26 percent over 2025.
There is no single answer, but the practical signal is when the requirements start costing you deals rather than the count stopping you outright. If reserve requirements are tying up cash you need for the next down payment, or a refinance you were counting on is not available, that is usually the point to have a conversation about portfolio lending.
Substantially. At five units and above the property is commercial multifamily. Conforming loan limits and financed property counts no longer apply, and the loan is underwritten primarily on the property's income and operating history rather than on residential guidelines.
The dollar limit is easy to look up. The count is the one that surprises people, and it is the one worth checking before you have a property under contract rather than after.
Whether you are buying your second rental or your twelfth, sit down with one of our lenders and walk through where you actually stand. We finance one-to-four-family and multifamily property across Minnesota, and we keep many of these loans on our own books.
