The Quick Read: Each house, duplex and condo in the pool counts as one property with its own lien and its own appraisal. The lender adds up the rent used for lender review from every property, adds up the full payment on every property, and divides once. Stronger rentals can offset weaker ones, but underwriting still reviews each property, and everything is subject to lender guidelines.
- A duplex is one property with two units. The count of properties and the count of units are different numbers.
- Rent used for lender review is usually the appraiser’s market rent, or the lease when a signed lease supports it. Your own projection does not set it.
- The pooled ratio is payment-weighted. It is not a simple average of each property’s ratio.
- A coverage number of 1.00 or better says nothing about positive cash flow.
- One note ties the properties together. That helps qualifying and hurts exit flexibility.
A mixed pool of houses, duplexes and condos sounds messy. In practice it is a clean sorting exercise. This guide walks through what the lender counts, how each property type feeds the number, and where the usual rules break.
Key Terms Defined
Portfolio DSCR loan: One loan, secured by several rental properties, qualified on the combined rent of all of them. Investors also call it a blanket loan or a cross-collateralized loan. All three names mean the same thing here.
Bank portfolio loan: A different use of the word. It means a bank keeps the loan on its own books. It says nothing about how many properties secure the loan.
Cross-collateralization: Every property in the pool backs the whole debt, not just its own share.
PITIA: Principal, interest, taxes, insurance and association dues. It is the full monthly obligation on a property.
Pooled coverage: Total rent used for lender review divided by total PITIA across the whole pool.
Allocated balance: The slice of the loan the documents assign to each property. It sets the price of releasing that property later.
Unit versus property: A property is one parcel with one lien. A unit is one rentable space inside it. A duplex is one property and two units.
What Does “Counting” Mean in a Portfolio Loan?
Three different counts run at the same time: properties, units and loans. Mixing them up causes most of the confusion around mixed pools.
The loan count is simple. A portfolio DSCR loan is one note, so the answer is one. A separate lien is recorded against each property, which is why each property still needs its own appraisal and title work.
The property count decides program eligibility. The 30-year portfolio DSCR loan, which Lendmire arranges through its wholesale network, takes 2 to 20 properties under one note. Loan sizes run from $300,000 to $5,000,000, with larger balances on review. A duplex is one of those properties.
The unit count matters in two places. It matters for rent, because every unit needs its own rent conclusion. It also matters on the rental portfolio term loan, which is written for five or more rental properties or units under one loan. Loan sizes there run from $500,000 to $50,000,000, with larger balances on review. A pool with two fourplexes and a condo can reach that threshold on units, even though it has only three properties.
So a duplex counts as one property and two units. Which of those numbers matters depends on the question you are asking.
How Does Each Property Type Count?
Each property type brings a different rent document and a different review. This table covers both structures. The 30-year portfolio DSCR loan takes single-family, 2-4 unit, condo and townhome. The rental portfolio term loan adds small multifamily.
| Property | Counts as | How rent is supported | Extra review |
|---|---|---|---|
| House | One property, one unit | Lease or appraiser rent schedule | Appraisal |
| Duplex | One property, two units | Rent for each unit | Appraiser’s income analysis |
| Condo | One property, one unit | Lease or appraiser market rent | Condo questionnaire, project review |
| Townhome | One property, one unit | Lease or appraiser market rent | Appraisal, HOA dues in PITIA |
| 5+ units | Term loan only | Rent roll and leases | Term-loan underwriting |
Houses
A house is the easiest line in the pool. The appraiser produces a market-rent opinion on a single-family comparable rent schedule, known as Form 1007 in the Fannie Mae forms list. An occupied house also needs an executed lease. The lender uses the lease and the appraiser’s number together.
Duplexes
A duplex is where the unit count shows up. The standard appraisal form for two- to four-unit buildings is Form 1025, the small residential income property report. The Fannie Mae Selling Guide says it also covers two- to four-unit properties inside condo, PUD and co-op projects. Only the form names matter here. Agency lending rules do not govern these loans.
On that form the appraiser gives a market-rent opinion for each unit. The unit rents add up to the building’s rent. Every unit needs a rent conclusion the appraiser can support. One strong unit cannot stand in for a weak or unsupported one.
A vacant unit does not count as zero. The appraiser’s market rent can support it, and most lenders want the file to show that clearly. How a vacancy is treated varies by lender, so raise it early.
Condos
A condo is one unit and one property. It also carries a second layer of review. The lender looks at the building or project, not just your unit, so a completed condo questionnaire belongs in the file. Monthly association dues go into the PITIA side of the ratio, so a condo with heavy dues covers less than its rent suggests. Project health can limit eligibility.
Townhomes
A townhome counts like a house in the pool, with one wrinkle. If it sits in an association, the dues enter the payment.
What stays out of the pool
Owner-occupied property, co-ops, mixed-use property and commercial property are ineligible in the pool.
Manufactured and mobile homes are not reviewable on any of these programs.
How Is the Pool Tested as One Number?
The lender totals rent used for program review across every property, totals the full PITIA across every property, and divides once. The result is one pooled coverage number, and on the 30-year portfolio DSCR loan the floor is 1.00, subject to lender guidelines.
Here is a modeled example. These inputs are assumptions, not market data. Picture a pool with one house, one duplex and one condo.
- House: covers its own payment at roughly 1.25x.
- Duplex: covers its own payment at roughly 1.10x, with both units’ rents supported.
- Condo: covers its own payment at roughly 0.90x, association dues included.
Now add one more assumption: how much of the pool’s total payment each property carries. Say the house carries 30%, the duplex 45% and the condo 25%.
The pooled ratio is each ratio times its share of the payment, added together. That is 0.375 for the house, 0.495 for the duplex and 0.225 for the condo, for a pooled result of about 1.10x.
A simple average of the three ratios would land near 1.08x. That is close, but it is the wrong method. The duplex carries the biggest payment, so it pulls the pooled number toward its own ratio. If the condo carried most of the debt, the pooled number would drop toward 0.90x.
This is the real benefit of pooling. A condo below 1.00 can sit in the pool when the combined coverage clears the floor. In that case underwriting tests the pooled coverage, the leverage and the terms. The condo does not get a free pass. It gets reviewed as part of a larger number.
(Some lenders in the network also look at individual properties. Ask early whether your lender does.)
Leverage works on the pool too. On purchase and rate-and-term, the 30-year structure goes up to 80% of value, and the rental portfolio term loan goes up to 75%. Those are program ceilings, and the lender sets the actual number file by file.
Two cost-basis caps to know
A newly bought pool faces a second cap on loan size. Inside the first six months the loan is also capped at 90% of total cost (purchase price plus documented improvements), and at 100% of total cost from six to twelve months. The leverage ceiling still applies, so the loan is the lower of the two. After twelve months the appraised value alone is the basis. A rate-and-term refinance is not subject to the cost-basis cap.
Cash-out on a portfolio loan never goes above 75% of the pooled value. Inside the first six months the same cost-basis cap applies.
Two ratio methods, one source of confusion
Some explainers qualify a portfolio on net operating income. If a page uses a different method, its numbers will not match yours. Check which one the lender uses before you compare files.
Counting Versus Coverage
The count decides whether the pool is eligible. The coverage decides whether it qualifies.
Count rules answer: how many properties, which types, what loan size. Coverage answers: does the pooled rent carry the pooled debt? You can clear one test and fail the other. A pool with strong coverage still fails if it has one property too many, or a single property type the program does not take.
Conventional agency loans handle this very differently. They tally financed properties against a cap on the borrower’s total number of mortgaged properties, so the count itself can block you. A portfolio DSCR loan counts properties differently, because the pool is one loan. The limit is the program’s own range, not a personal tally.
Credit sits alongside both tests. The floor on the portfolio programs is 640, and some structures ask for 680 or 720. A special-purpose entity, typically an LLC, is required on some structures, depending on program guidelines. Recourse loans carry a personal guarantee.
Loan structure comes next. The 30-year portfolio DSCR loan is fixed or adjustable, with a 30-year term and an interest-only period available. The rental portfolio term loan is fixed for 3, 5, 7 or 10 years with a balloon at maturity. It comes in recourse and non-recourse forms. A non-recourse loan looks to the real estate, with recourse limited to carve-outs such as fraud and bankruptcy. That term loan also carries yield-maintenance prepayment, so plan your exit before you pick it.
Across the network, one pattern shows up again and again on mixed pools. Investors sort the properties by coverage and think about the weakest one. The stronger files sort by something else first: which property they might sell soonest. That one decision shapes the structure more than the coverage math does.
One Note or Several?
One note buys you simplicity and pooled qualifying. It costs you exit flexibility. Separate loans keep each property independent, and each loan stands on its own coverage.
| Factor | One portfolio note | Separate loans |
|---|---|---|
| Closings | One | One per property |
| Qualifying | Pooled coverage | Each property alone |
| Weak property | Can ride with stronger ones | Tested by itself |
| Selling one | Release terms apply | Pays off that loan only |
| Default risk | Cross-collateralized | Contained to one property |
Selling one property out of a pool follows the loan documents and the lender’s release terms. The release price runs above the property’s allocated balance. The remaining pool must still cover its debt service.
A release clause lets a property out. It does not let a new one in. If you expect to add properties, ask whether the loan has any provision for it. Many do not.
Cross-collateralization cuts both ways. A problem on one property can reach the others, because they all back the same debt. Spreading that risk is the price of pooling.
Paid-down rentals deserve a second look before they go in. A property with little debt rarely needs the pool to qualify. Joining it adds shared-collateral exposure for little qualifying benefit.
Tax treatment varies by how you hold and sell the properties, so consult a qualified professional before you decide.
The broader complete DSCR loans guide covers how this loan type works in general.
Common Counting Mistakes
- Counting a duplex as two properties. It is one property with two units.
- Using your own rent projection. The appraiser’s market rent, or the lower of the lease and market, generally controls.
- Averaging the ratios. Pooled coverage is total rent over total payment.
- Forgetting association dues. Condos and townhomes carry them in PITIA.
- Reading 1.00x as profit. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities and capital expenses sit outside the calculation.
- Listing five-plus unit buildings in the 30-year pool. They fit only the rental portfolio term loan.
- Assuming a blended ratio above the floor ends the review. Underwriting still looks at each property, its appraisal and its documents.
- Skipping the exit plan. Selling one property depends on release terms. Check them first.
Before You Submit the Pool
A tidy file helps every lender in the review. Sort the pool and check these items:
- A lease for each occupied unit, plus a rent roll for each duplex.
- The appraiser’s rent schedule or income statement for each property.
- A completed condo questionnaire and the association dues for each condo or townhome.
- The entity that will hold title, and whether the loan is recourse or non-recourse.
- A note on which property you might sell first.
Frequently Asked Questions
Does a duplex count as two properties?
No. A duplex is one property with two units, secured by one lien and appraised once. The unit count still matters, because each unit needs its own supported rent. On the rental portfolio term loan, units can also count toward the five-or-more threshold.
Do condos count the same as houses?
Mostly, yes, with extra review. A condo is one property and one unit in the pool, just like a house. The lender also reviews the project and a condo questionnaire, and association dues enter the payment, which lowers the coverage the same rent produces.
Can I mix houses, duplexes and condos in one loan?
Yes. The 30-year portfolio DSCR loan takes single-family, 2-4 unit, condo and townhome properties together, up to 20 properties under one note, subject to lender guidelines. Owner-occupied, mixed-use and commercial property stay out.
What if one property sits below the coverage line?
It can still sit in the pool when the combined coverage clears the floor. Underwriting tests the pooled coverage, the leverage and the terms, and a property far outside the acceptable range can still hurt the file. Many lenders also review properties individually.
Does a fourplex change the count?
A fourplex is still one property with four units, so it fits the 30-year structure. It also adds four units toward the five-or-more threshold on the rental portfolio term loan. Buildings of five or more units are eligible only on that term loan.
