The Quick Read: A portfolio DSCR lender treats this pool as four buildings and seven rentable doors, adds up the rent used for lender review for every door, adds up the payment on the single new loan, and divides one by the other. That one blended number is the main test. Value, leverage, credit, reserves and property eligibility still have to pass on top of it, subject to lender guidelines.
- The pool is four properties, but the rent comes from seven doors. The fourplex contributes four rent lines.
- Each door uses the lower of the lease rent or the appraiser’s market rent.
- On the pooled structures in Lendmire’s network, coverage is measured on the whole pool, so strong buildings can offset weaker ones.
- Every property still needs rent evidence, a value and an eligible property type.
- Clearing the ratio is not the same as cash flow. Repairs, vacancy and management sit outside it.
What Is the Lender Actually Counting?
The lender counts four different things, and mixing them up causes most of the confusion. It counts assets (four buildings), doors (seven), rent lines (seven) and payments (one, for the whole loan). The ratio uses the rent total and the payment total. The collateral list uses the buildings.
Most investors picture four loans stapled together. That is not how it works. A blanket or portfolio loan is one note secured by several properties. Nav describes this as a blanket lien that lets multiple properties secure a single loan.
Think of it as one cash register and four shelves. All the rent goes into one register. All the shelves back one debt.
Key Terms Defined
DSCR (debt service coverage ratio): the property income divided by the debt payment. A reading of 1.00 means the rent just covers the payment. Below 1.00, it does not. Corporate Finance Institute explains the same idea in general business terms.
PITIA: principal, interest, taxes, insurance and association dues, the full monthly obligation on the loan.
ITIA: the same payment on an interest-only loan, with no principal in it.
Blended (pooled) coverage: total rent used for lender review across all properties divided by total payment on the single loan.
Cross-collateralization: every property in the pool backs the whole balance, not just its own share.
Release price: the amount you must pay down to pull one property out of the pool. It runs above that property’s allocated balance.
LTV (loan-to-value): the loan balance as a percentage of the appraised value.
The Pool on the Table
Here is the pool: three single-family houses and one four-unit building, all non-owner-occupied rentals, all held in the investor’s name or an LLC (an LLC is subject to lender program eligibility, and some structures require a special-purpose entity).
Lendmire’s network has two portfolio structures, and this pool fits both. The first is a 30-year portfolio DSCR loan. It covers two to twenty properties under one note, with loan sizes from $300,000 to $5,000,000 (larger balances on review). Leverage runs up to 80% of value on a purchase or rate-and-term refinance of investment rentals. Coverage is measured on the pool, with a 1.00 floor. Interest-only periods, fixed and adjustable types, and property types including single-family, 2-4 unit, condo and townhome are available, subject to lender guidelines.
The second is a rental portfolio term loan, which is built for five or more rental properties or units under one loan. This pool has seven units, so it is reviewed on count. Loan sizes run from $500,000 to $50,000,000 (larger balances on review). Leverage tops out at 75% of value. Terms are fixed at 3, 5, 7 or 10 years with a balloon at maturity. Recourse and non-recourse versions exist, and prepayment follows a yield maintenance structure. Reserves are held for taxes, insurance and capital expenditures.
Those are very different loans. One is a long amortizing note. The other is a shorter note with an exit plan baked in.
Both are separate from a loan on a single rental. A standard single-property DSCR loan typically lands at 75%-80% LTV on a purchase, with loan sizes up to $3,000,000 on standard programs. The portfolio figures above belong only to the portfolio structures.
How Underwriting Counts the Rent
Each door gets one rent figure, and that figure is the lower of the in-place lease rent or the appraiser’s market rent. The lender never uses the higher number. Rent that exists only in your head does not count.
The appraisal side differs by building type. A single-family house gets a rent schedule, commonly the 1007 form. The fourplex gets a small-residential-income report, commonly the 1025. Fannie Mae’s appraisal form guidance lists the 1025 for 2-4 unit properties and the 1004 for one-unit properties. The 1025 layout reports rent unit by unit and totals them. DSCR loans are not agency loans. These forms are simply the standard report formats appraisers already use.
So the houses give you three rent lines. The fourplex gives you four. Add them and you have seven door-rents.
A vacant unit is usually filled with the appraiser’s market rent instead of zero. Treatment varies by program, though, and a stricter reviewer may haircut an empty door. Plan for both.
How Underwriting Counts the Payment
The payment side is simpler. There is one loan, so there is one PITIA for the whole pool: principal, interest, taxes, insurance and association dues on the new note. On an interest-only period, the divisor becomes ITIA.
Existing mortgages on a refinance are paid off and rolled into the new note. So the old four payments disappear and one payment replaces them.
Taxes and insurance for all four buildings go into the total. They vary by county, so budget for them building by building.
The Step-by-Step Math
Here is the sequence a portfolio file follows:
1. List the four properties, how each is vested, and what debt sits on them now.
2. Collect a lease and an appraiser’s rent figure for every door.
3. Take the lower of the two for each door.
4. Add all seven door-rents.
5. Calculate the PITIA on the single new loan.
6. Divide total rent by total PITIA. That is the blended coverage.
7. Size the loan to the appraised value of the pool and the program’s LTV tier.
8. Review credit, reserves, entity documents and property eligibility.
Step 7 matters. The loan is the lower of what the equity allows and what the rent supports. Both tests have to pass.
The table below uses modeled assumptions, not market data. Each building carries a share of the total payment, and each has its own coverage.
| Property | Share of total payment | Own coverage | Adds to pool |
|---|---|---|---|
| House 1 | 20% | 1.15x | 0.23 |
| House 2 | 20% | 1.05x | 0.21 |
| House 3 | 20% | 0.95x | 0.19 |
| Fourplex (4 doors) | 40% | 1.30x | 0.52 |
| Pool | 100% | 1.15x |
The pooled number is a payment-weighted average. That is why the fourplex matters so much here. It carries 40% of the debt and the best coverage.
House 3 sits below 1.00 on its own in this model. Inside the pool, what underwriting tests is the pooled coverage, along with the leverage and the terms. Strong carries weak. The pool still reads 1.15x.
Does a Strong Fourplex Rescue a Weak House?
Often, yes, on the coverage test. Because pooled coverage is the number that matters on these structures, a strong building can offset a soft one. A fourplex spreads its rent over one building payment, so it frequently covers better than a single-family house. That is why mixed pools like this one get built in the first place.
Rescue has limits, though. Some portfolio programs elsewhere in the market add a property-level floor, and an underwriter can still flag a building that looks like an outlier. Every property needs a lease or an appraiser-supported market rent. Every property needs an eligible type and its own appraised value. A weak house cannot hide in the average on those tests.
The reverse also holds. A weak fourplex can drag a pool of decent houses down, because it carries the biggest share of the payment.
Stress Test: One Empty Door
Say one of the four fourplex doors goes empty, and the reviewer counts it at zero. That removes 25% of the building’s rent. These are modeled ratios, not quotes.
| Scenario | Fourplex coverage | Pool coverage |
|---|---|---|
| Base case | 1.30x | 1.15x |
| One door counted at zero | about 0.98x | about 1.02x |
| One door at zero, House 3 slips to 0.85x | about 0.98x | about 1.00x |
One empty door cuts the pooled number by about 0.13. Add one weaker house and the pool lands right on the 1.00 floor.
So the cushion is thinner than it looks. A pool at 1.15x can lose a door and still pass. A pool that starts at 1.05x cannot. The honest answer for most investors is to model the vacant-door case before applying, not after the appraisal comes back.
How Value and Leverage Blend
Leverage is set on the pooled appraised value. Each building is appraised on its own, the values are added, and the program’s LTV applies to the total. Each ceiling is a cap, never a promise.
On the 30-year structure, the cap is up to 80% of value on a purchase or rate-and-term refinance of investment rentals. On the term loan, it is up to 75% of value. A cash-out on the pool never goes above 75% of the pooled value, and never above the structure’s own ceiling.
Seasoning rules apply too. Inside the first six months of ownership, 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.
A bigger down payment can lower the payment and lift the ratio. It never erases a leverage cap, a credit floor or a property-type rule. The strongest files clear both tests: enough equity and enough rent coverage. Credit floors start around 640, and some portfolio structures want 680 or 720.
Here is a pattern from across a wholesale network. In mixed pools, the lowest-value house often causes more trouble than the weakest ratio. It is the property most likely to run into a minimum-value problem or an eligibility question, so it is worth asking early whether a small, cheap house belongs in the pool at all.
Cross-Collateralization, Release and Exit
This is where the structure costs you. Every property secures the whole balance. Nav notes that without a release clause, selling a single property becomes much harder. A due-on-sale clause can also bring the entire loan due.
Partial releases, substitutions and the sale of one property follow the loan documents and the lender’s release terms. The release price runs above the property’s allocated balance, so selling one house costs more than paying off its slice. The remaining portfolio must still cover its debt service afterward.
Picture selling the fourplex in year three. It carries 40% of the debt and the strongest coverage. Pull it out, and the three houses left behind are the weaker half of the pool. The remaining coverage could slip below the lender’s test. Exit planning for this mix really means exit planning for the fourplex.
The term loan adds one more wrinkle. Its balloon at maturity means you need a refinance or sale plan from day one. The 30-year structure amortizes over a long runway, which avoids that. The tradeoff is different leverage and terms.
Blanket or Four Separate Loans?
This is a genuine toss-up, and the better answer depends on what you plan to do with the properties.
| Factor | One portfolio loan | Four separate loans |
|---|---|---|
| Payments and closings | One note | Four notes |
| Coverage test | Pooled across all rents | Each property alone |
| Selling one property | Release terms apply | Sell freely |
| Default risk | Every asset exposed | Contained to one |
| Refinancing one | Touches the whole pool | Independent |
Separate loans keep each property independent and individually sellable. The portfolio loan trades that flexibility for one payment and pooled coverage. If you expect to sell a house in a few years, the flexibility is worth real money. If you plan to hold all seven doors, one note is simpler.
Pooled coverage also helps when one house on its own sits below what a single-property program wants. For a loan on one rental, coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. That is a different path from the pooled structure above. Compare both before choosing.
Tax treatment varies; consult a qualified professional.
For a wider view of how these loans fit together, Lendmire’s complete DSCR loans guide covers the basics.
Where the Rule Breaks
The general method holds up, but five edge cases bend it.
Not every blanket loan is DSCR. Some blanket loans are underwritten on business financials or a commercial-style income test, not residential rent over PITIA. The structures above use rent against payment on one-to-four unit rentals.
Property mix. Houses and 2-4 unit buildings are residential and mix freely in these programs. Small multifamily belongs to the term loan structure.
Ineligible property. Owner-occupied property, mobile homes, co-ops, mixed-use property and commercial property are not eligible in the pool. Manufactured homes, log homes and barndominiums are not offered in the network’s DSCR programs at all. A fifth property with one of those types sinks the whole file.
Low-value properties. Very cheap houses can be hard to place in a pool because of value minimums. Lender appetite varies.
Release friction. A release clause on paper can still be slowed by other loan covenants. Read the note before you sign, not after.
What the Ratio Leaves Out
A pooled 1.15x does not mean you are cash-flowing. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities and capital spending sit outside the calculation. A fourplex clearing its test can still lose money in a bad year.
Treat the ratio as the lender’s test and your own budget as a separate test. The investor who wins long term passes both. Run your own numbers with a reserve for each door, and ask whether one empty unit would hurt.
Reserves also matter at the lender level. They commonly run around 6 months of PITIA on single-property files, and they step up to about 9 months above $1,500,000. Portfolio structures hold reserves for taxes, insurance and capital expenditures. Details vary by lender, leverage and loan size.
Frequently Asked Questions
Is the fourplex one property or four?
Both, depending on the test. It is one property for collateral, appraisal and payment. It is four doors for rent, because the 1025 report lists each unit’s rent and totals them. That is why a fourplex adds four rent lines to the pool but only one building to the property count.
Do vacant units count?
Usually yes, at the appraiser’s market rent instead of zero. Treatment varies by program, and a stricter reviewer may count a vacant door at less. Model the zero case so you know how thin the cushion is.
Is my pool too small for a blanket?
No. The 30-year portfolio structure starts at two properties, so four properties fits comfortably. Loan size matters more than count, since the structure starts at $300,000 and the term loan at $500,000, subject to lender guidelines. If your total balance falls below those minimums, separate loans make more sense.
What if I only want to sell the fourplex later?
Plan for a release price that runs above the fourplex’s allocated balance. Because the fourplex likely carries the largest share of the debt and the best coverage, removing it can leave a weaker remaining pool. The remaining portfolio must still cover its debt service. Ask about release terms before you sign.
Can an LLC hold the properties?
Often, and some structures require a special-purpose entity, subject to lender program eligibility. Recourse loans carry a personal guarantee. Non-recourse versions exist on the term loan, with carve-outs such as fraud and bankruptcy.
