Conventional financing is the cheapest long-term debt a small landlord can get, and you should use it for as long as it will have you. At some point it stops: too many financed properties, title in an LLC, a building that does not fit the box. A portfolio loan is what picks up from there, and it charges for the privilege.
The charge is measurable. On the example $180,000 loan worked below, portfolio terms cost about $162 a month more than conventional terms and about $6,798 more over five years in interest and points. Knowing that number turns "should I switch lenders" into an ordinary cost and benefit question.
What a portfolio loan is and who writes them
Most residential mortgages are written to be sold. The lender closes the loan, sells it to Fannie Mae or Freddie Mac, and uses the cash to lend again. To be saleable the loan has to follow the agencies' rulebook exactly, which is why every conventional lender asks for the same documents and says no to the same things.
A portfolio loan is one the lender keeps on its own balance sheet. Because nobody downstream has to approve it, the lender writes its own rules. It can lend to your LLC, ignore how many other mortgages you have, count income the way a business lender would, and finance a property the agencies would reject.
The lenders who do this are mostly community banks, credit unions and some regional banks, usually through a commercial or business banking officer instead of the retail mortgage desk. They are lending their depositors' money and they hold the risk, so they care about two things conventional underwriting barely considers: the whole relationship with you, including deposits, and the quality of your operation as a business.
DSCR loans are the productized cousin. They are also outside the agency system, but they come from national non-bank lenders using standardized guidelines, and they qualify the loan on the property's rent instead of your personal income. They are closer to a catalog product than a negotiated one. This post does not re-explain them, and the DSCR explainer covers how the ratio is computed and what minimums lenders commonly want. For the decision here, think of DSCR loans as the option you can get in any state with a phone call, and bank portfolio loans as the option you have to go find and negotiate.
Where conventional stops: the walls investors hit
The financed-property limit. Fannie Mae's long-standing cap is 10 financed residential properties per borrower, counting your own home, and requirements for credit and reserves tighten well before you reach the cap. Many individual lenders stop earlier as an internal policy. Confirm the current count and the reserve rules with a loan officer, because this is the kind of guideline that gets revised. Whatever the exact number is when you read this, a growing investor reaches it.
Title in an entity. Conventional loans are made to individuals. You cannot close one in the name of an LLC. Moving the title into an LLC after closing gives the lender the right to call the loan under the due-on-sale clause. Enforcement is rare, but "rare" is a thin foundation for a portfolio you plan to hold for decades. Portfolio lenders lend to the entity directly, usually with your personal guarantee.
Properties outside the box. Five or more units, mixed-use buildings with a storefront, several houses on one parcel, condos in projects the agencies will not approve, rural property with acreage, and houses in rough condition all fall outside conventional rules. A bank that knows the street can lend on them.
Income that does not document well. Conventional underwriting runs on tax returns and a debt-to-income ratio. Self-employed investors with heavy write-offs often show too little income on paper, even with strong cash flow. A portfolio lender can look at the global picture: all properties, all debt, actual cash in and out.
Speed and seasoning. Conventional guidelines impose waiting periods before a cash-out refinance. A portfolio lender sets its own and may refinance a renovated property sooner.
If none of these walls applies to you, you do not need a portfolio loan, and paying for one is a mistake.
The price of flexibility: rate, points, and terms compared
Portfolio loans differ from conventional loans in structure as much as in rate. The patterns below are common, not universal, and every figure in the worked example is a labeled example.
| Term | Conventional investment loan | Bank portfolio loan |
|---|---|---|
| Rate | Lowest available for rentals | Commonly higher |
| Rate type | Fixed for 30 years | Commonly fixed for 5, 7 or 10 years, then resets or balloons |
| Amortization | 30 years | Commonly 20 or 25 years |
| Origination | Points optional | Commonly 1 to 2 points |
| Prepayment penalty | None | Common, often stepping down over the early years |
| Borrower | Individual | Entity with personal guarantee |
| Underwriting | Agency rulebook, debt-to-income | Lender's judgment, property DSCR and global cash flow |
Worked example: one deal, two term sheets
An example rental costs $240,000 with 25% down, so the loan is $180,000 either way. Net operating income is $1,600 a month. The conventional offer is an example 7.00% fixed for 30 years with 1 point. The portfolio offer is an example 7.75%, amortized over 25 years, fixed for 5 years with a balloon at the end of year 5, and 1.5 points.
| Example comparison on a $180,000 loan | Conventional | Portfolio |
|---|---|---|
| Monthly principal and interest | $1,198 | $1,360 |
| Monthly cash flow on $1,600 NOI | $402 | $240 |
| DSCR | 1.34 | 1.18 |
| Points paid at closing | $1,800 | $2,700 |
| Interest paid over 60 months | $61,290 | $67,188 |
| Principal paid over 60 months | $10,563 | $14,388 |
| Total payments over 60 months | $71,853 | $81,576 |
| Balance at month 60 | $169,437 | $165,612 |
Each column ties: interest plus principal equals total payments, and $180,000 minus principal paid equals the ending balance.
The payment gap is $162 a month, or $1,944 a year out of cash flow. Part of that is not a cost. The 25-year schedule forces $3,825 more principal paydown over five years, and that money is still yours as equity. The true price of the flexibility is the extra interest plus the extra points:
- Extra interest over 60 months: $67,188 - $61,290 = $5,898
- Extra points: $2,700 - $1,800 = $900
- Total: $6,798, or about $1,360 a year
That is the figure to weigh against what the loan makes possible. If the alternative is not buying the property at all because conventional lenders have stopped approving you, $1,360 a year is cheap. If the alternative is a conventional loan you still qualify for, it is $6,798 spent on nothing.
The rate is the smaller risk. The balloon is the larger one. At month 60 the portfolio borrower owes $165,612 and has to refinance, pay it off, or accept whatever rate the bank offers at renewal. The conventional borrower has 25 more years of a known payment. When you take a portfolio loan you are accepting refinance risk every five to ten years across your portfolio, so stagger the maturities and keep the DSCR high enough that a renewal at a higher rate still works. Here the portfolio DSCR starts at 1.18, which leaves little room. A reset to a higher rate on that balance could push it toward 1.0.
Blanket features: many doors, one loan
A blanket loan is one mortgage secured by several properties. Portfolio lenders write them because they can. For an investor with many small loans, a blanket can replace a stack of payments and escrow accounts with one note and one renewal date, and it sidesteps per-property loan minimums that make financing cheap houses awkward.
The terms that matter in a blanket loan are different from a single-property loan.
Release clauses. You need the right to sell one property without paying off the whole loan. The lender will set a release price, commonly above that property's share of the debt.
Example: five houses worth $200,000 each secure a $700,000 blanket loan, which is 70% of the $1,000,000 total value. Each house carries an allocated $140,000. The release price is an example 115% of the allocation.
| Example sale of one house under a blanket loan | Amount |
|---|---|
| Sale price | $200,000 |
| Selling costs at an example 7% | -$14,000 |
| Net sale proceeds | $186,000 |
| Release price, $140,000 x 115% | -$161,000 |
| Cash to you | $25,000 |
| Cash to you if the house had its own $140,000 loan | $46,000 |
The extra $21,000 is not lost. It pays the blanket down to $539,000 against $800,000 of remaining value, a 67.4% loan-to-value. It is still cash you expected and did not receive, so read the release clause before you need it.
Cross-collateralization. Every property secures the whole debt. Trouble with one house is trouble with all five. A default on the blanket puts the entire group at risk, where separate loans would have contained the damage.
One maturity. A single balloon date on $700,000 is a bigger event than five staggered ones.
To underwrite a blanket loan, treat the group as one multi-unit property with one rent roll and one debt payment. Entering five houses as five units in the multifamily calculator gives you the combined NOI, DSCR and cash flow the way the bank's credit officer will see them.
How to find and pitch portfolio lenders
You will not find these loans on a rate comparison site. Work the phone.
- List the community banks and credit unions with branches near your properties. Local lenders lend locally.
- Ask for a commercial or business lender, and ask one question: "Do you hold loans on one to four family investment property in your own portfolio, and do you lend to LLCs?" The answer takes ten seconds.
- Ask other investors, property managers and title officers who is lending right now. Bank appetite changes with each bank's balance sheet.
When you get a meeting, bring a package. A banker who sees an organized borrower prices the risk lower.
- A schedule of real estate owned: address, value, loan balance, rate, payment, rent, and net income for each property
- Current leases and a rent roll
- A personal financial statement and two years of tax returns
- Entity documents for the borrowing LLC
- A one-page summary of the request: property, price, loan amount, and the DSCR at the bank's likely rate
Then get the full term sheet in writing. Ask for the rate and how long it is fixed, the amortization, the balloon date, what index and margin apply at reset, the prepayment penalty, points and fees, maximum loan-to-value, minimum DSCR, whether the loan is recourse, and any deposit relationship the bank expects. Two banks quoting the same rate can differ by thousands of dollars in the other terms.
The decision rule by portfolio size
| Where you are | Default choice | Reason |
|---|---|---|
| Financed properties 1 to 4 | Conventional | Lowest rate, 30-year fixed, no balloon. The walls have not appeared yet. |
| Financed properties 5 up to the conventional cap | Conventional while it approves you, portfolio or DSCR when it does not | Reserve and credit requirements rise and approvals slow. Start a bank relationship before you need it. |
| Beyond the conventional cap | Portfolio, DSCR or a blanket loan | Conventional is closed. Compare a bank's negotiated terms against a DSCR lender's 30-year fixed offer. |
| Any size, with entity title or an unusual property | Portfolio | The property or the ownership structure decides, not the count. |
The ranges in the first column are guides. The logic underneath them is fixed: take the cheapest 30-year money available to you until a wall stops you, then pay for flexibility only on the deals that need it. Investors who move everything to bank debt early give up years of fixed-rate certainty for convenience.
Before you sign a portfolio term sheet, price it. Run the same property in the single family calculator twice, once at conventional terms and once at the portfolio rate, amortization and points. The difference in cash flow, DSCR and five-year equity is exactly what the flexibility costs in dollars. If the deal still clears your minimum return at portfolio terms and survives a higher rate at the balloon, the loan is doing its job.
