The Quick Read: A portfolio DSCR lender counts units in two separate ways. It counts the units inside each building to decide the property type and rent evidence, and it counts the properties in the pool to decide whether the loan structure applies. Pooled rent is then divided by pooled debt service to produce one coverage ratio, subject to lender guidelines.
- A single-family home, condo, or townhome counts as one unit. A duplex through a fourplex counts as one property with two to four units.
- On the 30-year portfolio loan, the pool needs two to twenty properties, and coverage is measured on the whole pool with a 1.00 floor.
- The rental portfolio term loan is built for five or more rental properties or units, and it also accepts small multifamily.
- Mixed-use and commercial property are not eligible inside the pool, and manufactured homes, log homes, and barndominiums are not offered at all.
- The real decision is which test applies (pooled or per property) and what you give up for it, such as exit flexibility.
Key Terms Defined
DSCR (debt service coverage ratio): Monthly rent divided by the monthly housing obligation. That obligation is principal, interest, taxes, insurance, and association dues, known together as PITIA.
Unit: One rentable living space with its own lease or market rent, such as one apartment in a fourplex.
Property: One building or parcel on the pool schedule. A fourplex is one property with four units.
Blanket (cross-collateralized) loan: One note secured by two or more properties, each pledged against the whole balance.
Portfolio loan: A loan the lender keeps on its own books. People use the word loosely for blanket loans, but the two are not the same thing.
Allocated loan amount: The share of the total balance assigned to each property. It drives release terms.
Release clause: The loan term that lets one property leave the pool, usually after a paydown above its allocated balance.
Non-QM: A loan category outside standard owner-occupied mortgage rules. DSCR loans sit here as business-purpose investor loans.
What Does Count Mean in a Pooled Loan?
Count is an overloaded word in this niche. A lender may mean five different things by it, and each one controls a different decision. Sorting them out before you shop saves a lot of confusion.
| Meaning | What it controls |
|---|---|
| Units in a building | Property type, appraisal form, rent evidence |
| Properties in the pool | Whether the structure’s minimums are met |
| Notes | Whether loans are cross-collateralized |
| Collateral pool | Pooled coverage and aggregate leverage |
| Allocated balance | Release terms for each property |
No regulator sets these rules. DSCR loans are business-purpose products, so each lender’s guidelines and the loan’s collateral structure decide how counting works. Across the wholesale network Lendmire places files with, the broad pattern holds. The unit count sets the property type, and the property count sets the structure.
How Does the Unit Count Change by Property Type?
Each property type counts differently, and the type also decides what rent evidence the lender needs. Here is how the network’s portfolio programs treat the common types.
| Property type | Counts as | Rent evidence |
|---|---|---|
| Single-family | 1 unit, 1 property | Lease or market rent |
| Condo or townhome | 1 unit, 1 property | Lease or market rent, plus dues |
| Duplex to fourplex | 2–4 units, 1 property | Rent for each unit |
| Small multifamily | Term loan structure only | Rent for each unit |
| Mixed-use or commercial | Not eligible in the pool | Not applicable |
A few notes on that table:
- A fourplex is one property, not four. It adds four units of rent, but it adds only one property to the pool count.
- Condos and townhomes count as one unit each. Their association dues go into the monthly obligation, which can pull coverage down.
- Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in these programs. They do not count as anything.
The industry draws the line between small and large buildings at four units. Properties with two to four units are treated as residential. Five or more units are treated as multifamily, which usually moves the loan toward commercial-style underwriting. That line is a convention inherited from agency definitions, not a law. Non-QM programs can flex above it, which is why the term loan structure below accepts small multifamily.
How Does the Lender Build the Coverage Ratio?
The lender builds one ratio in six steps. Each step is a place where the unit count matters.
1. Classify each asset. The lender sorts every property by type and unit count.
2. Set the rent for each property. The source is a lease for each unit or an appraiser-supported market rent. Every property needs one or the other.
3. Compute each property’s PITIA. Principal, interest, taxes, insurance, and dues are allocated to that property.
4. Choose the test. On a pooled loan, total rent is divided by total PITIA. On separate loans, each rental is tested alone.
5. Test aggregate leverage. Total loan balance is divided by total appraised value across the pool.
6. Set the release terms. Allocated balances and the release clause decide how one property can leave later.
The pooled test is what lets stronger properties offset weaker ones. That is the core appeal of a pooled structure. It also means a weak property drags on the whole group.
Which Appraisal Form Does Each Type Use?
Agency guides name the forms by unit count, and appraisals on these files tend to follow the same split. For a one-unit investment property where rental income is used, the Fannie Mae Selling Guide points to Form 1007, the Single-Family Comparable Rent Schedule. The HUD Mortgagee Letter 2023-17 pairs Forms 1004 and 1007 with one-unit properties. It pairs Form 1025, the Small Residential Income Property Appraisal Report, with two-to-four-unit properties.
That is a contrast reference only. DSCR files follow the lender’s own guidelines, not agency selling rules. The practical point is that a pool with single-family homes and small multi-unit buildings carries different paperwork for each asset.
Which Portfolio Structure Fits Your Count?
Two portfolio structures exist across the network, and they count differently. The figures below are program ceilings and floors, not quotes, and they are subject to lender guidelines.
| Factor | 30-year portfolio loan | Rental portfolio term loan |
|---|---|---|
| Count | 2 to 20 properties | 5+ properties or units |
| Loan size | $300,000 to $5,000,000 | $500,000 to $50,000,000 |
| Leverage | Up to 80% (purchase, rate-and-term) | Up to 75% |
| Terms | 30-year, interest-only available | Fixed 3, 5, 7, 10-year, balloon |
| Property types | SFR, 2–4 unit, condo, townhome | Same, plus small multifamily |
Larger balances on either structure are handled on review. The 30-year loan measures coverage on the pool with a 1.00 floor. The term loan offers recourse and non-recourse versions. A non-recourse loan looks to the real estate, with carve-outs for fraud and bankruptcy. A recourse loan carries a personal guarantee. Prepayment on the term loan runs on a yield maintenance schedule. Properties in several markets can sit under one loan.
Contrast this with a loan on one rental. That product typically lands at 75%–80% leverage on a purchase, and its loan size guide and reserve rules differ from the pooled programs. Do not mix the two sets of figures when you compare quotes.
Cash-out follows the standard ceiling. On a pooled cash-out refinance, leverage never goes above 75% of pooled value, and never above the structure’s own ceiling. In the first six months of ownership, cash-out is capped by a seasoning rule.
A Worked Example With Mixed Property Types
Run the numbers on a four-asset pool. These are modeled assumptions, not market data. Assume every property carries similar debt service, so each one weighs equally in the pooled ratio.
| Asset | Standalone coverage |
|---|---|
| Single-family | 1.25x |
| Duplex | 1.10x |
| Fourplex | 1.20x |
| Condo | 0.90x |
| Pooled coverage | 1.11x |
Add the four ratios and divide by four, and you get roughly 1.11x. The pool clears the 1.00 floor on the 30-year portfolio structure. The condo sits below 1.00 on its own. That does not make it a sub-1.00 loan. Inside the pool, the pooled coverage, the leverage, and the terms are what underwriting tests, subject to underwriting.
What Happens If One Unit Goes Vacant?
Now stress it. Say one unit in the fourplex has no tenant and no lease. With four equal units, that property loses a quarter of its rent, so it drops from 1.20x to 0.90x. The pooled ratio falls to roughly 1.04x. It still clears 1.00, but the cushion is thin.
Now consider what a lender does with that vacant unit. Typically it counts only leased or appraiser-supported rent. A unit you cannot show a lease or market rent for adds debt without adding coverage. This is why every unit needs its own rent evidence, not one document per building.
Where the General Rule Breaks
Several edge cases trip up investors who assume the count works the same everywhere.
- Batch closings are not blankets. Several loans closed together, each on its own note, are not cross-collateralized. Each rental is tested alone, whatever the marketing calls it.
- Property count versus unit count. The 30-year structure asks for two or more properties. A single fourplex has four units but only one property, so it does not meet that count. The term loan counts properties or units, so five or more units can matter there.
- Mixed-use buildings. A building with a storefront and apartments is not eligible inside the pool. The same goes for commercial property, co-ops, and owner-occupied property.
- Five-plus-unit buildings. These move to the term loan structure, which accepts small multifamily. Many pooled products are really bundles of separate one-to-four-unit rentals.
- Condo and townhome dues. Dues enter PITIA, so a condo with high dues can run much weaker than a similar house.
- Reclassification. If one asset’s type changes, such as a unit count revised by the appraiser, the whole file’s treatment can shift.
- Credit floor by structure. The pool credit floor is typically 640, and some portfolio structures want 680 or 720. A loan on one rental can run lower.
In one common file pattern, a strong single-family home offsets a weak condo, and the borrower assumes the pool is safe. The trouble comes later. When the borrower tries to sell the strong home, the release clause requires a payoff above that property’s allocated balance, and the remaining pool must still cover its debt service.
What Should You Decide Before Choosing a Structure?
Start with the question that matters. It is not how many units you own. It is which test applies, and what you give up to get the blend. A pooled loan trades exit flexibility and cross-default risk for the benefit of offsetting. Separate loans keep each lien independent, but they mean more closings and more payments.
Ask a lender these questions before picking assets:
- Is coverage tested on the pool, on each property, or both?
- How does the lender group one-unit, two-to-four-unit, and larger assets, and can they mix in one pool?
- What are the minimums for property count and loan size?
- How are release, substitution, and partial sale handled?
- Is the note recourse or non-recourse, and does a special-purpose entity (typically an LLC) apply, subject to lender program requirements?
Prepare a schedule of every property, a rent roll showing each unit, and a lease or appraiser rent for each unit. Reserves vary by structure, leverage, and loan size. On a loan against one rental, they commonly run around 6 months of PITIA. The term loan holds reserves for taxes, insurance, and capital expenditures. Confirm how your structure counts them rather than assuming they multiply across the pool.
A larger down payment lowers the payment and can lift coverage. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. And clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital spending all sit outside the ratio.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.

Frequently Asked Questions
Does a fourplex count as four properties or one?
One property with four units. The unit count sets the property type and the rent evidence. The property count sets whether you meet a structure’s minimum. A single fourplex cannot satisfy a two-property minimum on its own.
Can a weak rental sit in a pool with stronger ones?
Yes, on a pooled structure, because coverage is measured on total rent against total debt service. Underwriting still tests the pooled coverage, the leverage, and the terms, subject to lender guidelines. Some programs also check each property alone, so ask which test applies.
Do mixed-use buildings or manufactured homes qualify?
No. Mixed-use and commercial property are ineligible inside the pool. Manufactured homes, log homes, and barndominiums are not offered through the network’s DSCR programs.
Is four units a legal limit for DSCR loans?
No. It is an industry convention that separates small residential from multifamily. Non-QM programs can flex above it. The rental portfolio term loan, for example, accepts small multifamily and counts five or more properties or units.
Does a larger pool mean a higher leverage cap?
Not by itself. The 30-year portfolio loan goes up to 80% on a purchase or rate-and-term refinance. The term loan goes up to 75%. Cash-out on a pool never exceeds 75% of pooled value.
