The Quick Read: Two tests, run on the whole pool, set the loan: one built on pooled rent and one built on pooled value. The lender funds the smaller result, then subtracts existing payoffs, costs, and escrows, so the cash you receive usually falls well below the equity on paper.
- Cash-out on a portfolio loan tops out at 75% of pooled value on standard rentals, and never above the structure’s own ceiling.
- Coverage is measured on the pool: total rent used for lender review divided by total PITIA on the new loan, with 1.00 as the floor on the 30-year portfolio structure.
- Seasoning runs from the date the deed records, and a recent purchase can cap the loan below the leverage ceiling.
- Passing the coverage test is not the same as positive cash flow, because repairs, vacancy, and management sit outside the ratio.
- Subject to lender guidelines, every property still needs a lease or an appraiser-supported market rent.
Investors with several rentals often ask how big a single loan they can get against all of them. The answer is not “75% of what the properties are worth.” It is the lower of two numbers, and which one binds changes from pool to pool. This article walks through the mechanics step by step, the structures that exist, the cases where the general rule bends, and how the decision looks in practice. Lendmire’s complete DSCR loans guide covers the broader product if you want the foundation first.
Key Terms Defined
Pooled value: the combined appraised value of every property securing the one loan.
Pooled coverage: total rent used for lender review across the pool divided by the total monthly PITIA on the new loan.
PITIA: principal, interest, taxes, insurance, and association dues, the full monthly obligation on a property.
Seasoning: how long you have owned a property, measured from the date the deed records.
Net proceeds: what is left of the new loan after payoffs, closing costs, and funded escrows.
Blanket loan: one note secured by several properties. Here, “portfolio DSCR loan,” “blanket loan,” and “cross-collateralized loan” all name that same thing. A bank’s “portfolio loan,” meaning a loan the bank keeps on its own books, is a different use of the word.
What Does “Sizing” Mean on a Portfolio Loan?
Sizing means finding the largest loan the pool can support, not the loan you ask for. On a single rental, a lender checks one property against one set of limits. On a portfolio, the lender stacks every property into one set of totals and checks those totals against the same limits.
The structure itself is simple. Innago describes a blanket mortgage as a single loan covering multiple properties, held as collateral against one another. That shared collateral is why the lender reads the pool as a unit rather than as separate files.
One point of vocabulary matters before the math. Residential investor files across Lendmire’s wholesale network measure coverage as rent divided by PITIA. Commercial and online explainers often define the ratio as net operating income divided by debt service. Stessa and AirDNA both use that net-income version. The two are not interchangeable, so a ratio quoted in a blog post may not match the number a residential lender computes on your file.
How Does Underwriting Size the Loan, Step by Step?
Underwriting follows a fixed sequence, and each step asks a different question. Here is the order the programs across the network typically follow, subject to lender guidelines.
1. Classify the transaction. If any cash comes back at closing, the file is a cash-out, and the cash-out limits apply. A refinance that only pays off existing debt is treated as payoff-only, which has its own, higher ceiling.
2. Value each property. Each door gets its own appraisal and value basis. Your own after-repair estimate is a planning number, not a loan input.
3. Set the basis by seasoning. Seasoning is measured from the date the deed records, not from the day a rehab ends. Cash-out proceeds generally need about six months of ownership. A recent purchase also carries a second cap on the loan amount: the loan cannot exceed 90% of total cost (purchase price plus documented improvements) inside the first six months of ownership, or 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, appraised value alone is the basis. A rate-and-term refinance is not subject to the cost-basis cap.
4. Apply the leverage cap. A portfolio cash-out never exceeds 75% of pooled value on standard rentals.
5. Establish rent for each property. Rent comes from a lease, an appraiser’s market-rent opinion, or both, and the lower figure often wins. The appraiser’s rent schedule is Form 1007 for a single-family home and Form 1025 for a two-to-four unit property. A vacant unit relies on the market-rent schedule alone.
6. Compute pooled coverage. Add the rent used for lender review, add the PITIA on the new loan, and divide. The 30-year portfolio loan sets a floor of 1.00 on that pooled number.
7. Back-solve the rent-supported loan. Pooled rent divided by the floor gives the largest monthly obligation the pool can carry. The lender then works backward to the loan that produces that obligation.
8. Take the lower of the two loans. The rent-supported loan and the leverage-supported loan are compared, and the smaller one wins.
9. Subtract payoffs, costs, and escrows. What remains is your net cash.
10. Check reserves and documents. Reserves commonly run about 6 months of PITIA, stepping up to about 9 months on loans above $1,500,000, though they vary by lender, leverage, and loan size.
Interest-only periods change step six. When a structure offers one, the payment in the ratio shifts from full PITIA to interest, taxes, insurance, and dues. Confirm how the specific program treats it before you plan around the result.
Salary does not enter this sequence. On DSCR files, W-2 wages do not size the loan. They can matter for credit, reserves, and any personal guarantee, but the file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
One Worked Example: Which Limit Binds?
The cleanest way to see the two-limit rule is to run one pool two ways. The figures below are modeled assumptions, expressed as percentages and ratios rather than dollars, and they are not market data. Picture a pool of four seasoned rentals with a combined appraised value you can call 100 units, carrying existing loans equal to 50% of that value.
| Step | Scenario A: strong rents | Scenario B: thin rents |
|---|---|---|
| Leverage cap | 75% of pooled value | 75% of pooled value |
| Coverage at that loan | About 1.10x | About 0.92x |
| Does rent support the cap? | Yes | No |
| Binding limit | Leverage | Rent |
| Approximate loan | 75% of value | Roughly 69% of value or lower |
| Payoffs | 50% of value | 50% of value |
| Cash before costs | About 25% of value | About 19% of value or lower |
In Scenario A, the pool clears the floor with room to spare at the maximum loan, so the leverage cap decides the answer. In Scenario B, the pool falls short of 1.00 at the cap, so the lender shrinks the loan until pooled coverage reaches the floor. The loan scales roughly in proportion to coverage, which is where 69% comes from (75% times 0.92). Taxes and insurance do not shrink with the loan, so the true figure lands somewhat lower.
Notice what changed between the scenarios. Value stayed the same and the equity stayed the same. Only rent moved, and it cut the available cash by roughly a quarter. A high-equity, low-rent pool hits the rent limit first, while a low-equity, high-rent pool hits the leverage cap first.
What Moves the Number?
Six inputs drive the final figure, and they do not carry equal weight.
| Lever | Direction of effect | Size of effect |
|---|---|---|
| Appraised value | Higher value raises the leverage-based loan | Large |
| Rent used for program review | Higher rent raises the rent-based loan | Large when rent binds |
| Existing debt | More payoff shrinks net cash, not the loan | Large on net cash |
| Seasoning | A recent purchase can cap the loan at cost | Large on new buys |
| Payment structure | Interest-only can lift coverage on paper | Moderate |
| Closing costs and escrows | Reduce net cash dollar for dollar | Small to moderate |
Payoffs deserve the most attention. They take the biggest bite out of most cash-out files, which is why gross equity and net proceeds are two different numbers. A larger equity position does not erase leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests at once: enough equity and enough rental coverage.
Where Does Pooling Help, and Where Does It Hide Risk?
Pooling helps a mixed-quality portfolio qualify, and it hides the weak property from the headline number. Take four doors with equal payments: three near 1.25x coverage and one near 0.85x. The blend works out to roughly 1.15x. A property below 1.00 can sit in a pool like this one, but underwriting tests the pooled coverage, the leverage, and the terms.
Some lenders test individual doors as well as the blend. If one door is weak enough to draw that scrutiny, refinancing it on a separate note can be cleaner than letting it ride in the pool.
Cross-collateralization is the cost of pooling. Every property backs the whole balance, so one default can put several assets at risk. Innago lists higher down payments, cross-collateralization foreclosure risk, and limited lender availability among the main drawbacks.
Release clauses are the other half of the exit story. They are common but not guaranteed, according to Goliath Data’s blanket mortgage overview. In practice, the release price runs above the property’s allocated balance, and the remaining pool must still cover its debt service afterward. Terms worth negotiating include whether release is mandatory or discretionary, what triggers a retest, and the minimum number of properties that must remain.
| Factor | One pooled note | Separate notes |
|---|---|---|
| Weak property | Absorbed by stronger ones | Judged alone |
| Default exposure | Every property backs the loan | Isolated per property |
| Selling one property | Governed by release terms | Pay off that note |
| Closings and payments | One of each | One per property |
For two or three properties, most investors end up on individual loans, because blanket programs carry minimum property counts and loan sizes. Splitting a large portfolio into several blankets contains risk but gives up some exit flexibility.
Which Structures Exist?
Two portfolio structures cover most files, and they differ in size, term, and what they allow.
The 30-year portfolio DSCR loan secures 2 to 20 properties under one note, with loan sizes from $300,000 to $5,000,000 (larger balances on review). It offers fixed or adjustable structures on a 30-year term, with an interest-only period available. Property types include single-family, two-to-four unit, condo, and townhome. Leverage runs up to 80% of value on a purchase or a payoff-only refinance, and cash-out never exceeds 75% of pooled value on standard rentals. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
The rental portfolio term loan is built for five or more rental properties or units, with loan sizes from $500,000 to $50,000,000 (larger balances on review). Leverage goes up to 75% of value. Terms are fixed at 3, 5, 7, or 10 years with a balloon at maturity, and prepayment runs by yield maintenance. Non-recourse structures exist, with carve-outs such as fraud and bankruptcy, while recourse versions carry a personal guarantee. Properties in several markets can sit under one loan, and this is the only structure where small multifamily of five or more units is eligible. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Credit for the pool starts around a 640 floor, with 680 or 720 required on some structures. Some structures require a special-purpose entity, typically an LLC, depending on program guidelines. The entity on the new note must match the entity on title.
These programs do not cover owner-occupied property, co-ops, mixed-use property, or commercial property. Manufactured and mobile homes are not reviewable on any of these programs.
Where Does the General Rule Break?
Several edge cases change the answer, and each one has a clear tell.
A fresh purchase in the pool. A property you bought recently carries the cost-basis cap described in the sequence above. Strong coverage does not waive seasoning, so one new acquisition can hold down the loan on the whole pool.
Short-term rentals. Cash-out against short-term-rental collateral is capped near 70%, versus 75% for standard rentals. Hosting history and a documented income record come into play too. Lendmire’s piece How a Portfolio Refinance Sizes Cash-Out on Short-Term Rentals covers that path. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
The outlier property. A single door with soft rent or a low appraisal can drag the pooled number. The question to ask is whether the pool is better with that property in it or on its own note.
Max leverage with a thin cushion. Pulling the full amount leaves little room for a low appraisal, softer rents, or an insurance jump.
Mixed seasoning. A pool of old holdings and recent buys is sized property by property on basis, then rolled up.
The counting trap on conventional files. On conventional financing, folding mortgages into a bank’s blanket does not free up financed-property slots, because each property still counts. DSCR loans work differently and are not agency products.
Does Passing the Test Mean You Cash Flow?
No. Clearing 1.00 means rent covers PITIA, and that is all it means. Repairs, vacancy, management, utilities, and capital expenditures sit outside the calculation. A pool at 1.25x can still bleed cash in a bad quarter.
The practical habit is to size to the property rather than to the ceiling. Take the maximum only if the pool still works after you subtract a realistic vacancy and maintenance allowance. A lower loan with a wider cushion often beats the maximum draw, because maximum leverage leaves little room if an appraisal comes in light or rents soften at renewal, and a smaller draw keeps flexibility for the next acquisition.
What Should You Do With the Proceeds?
The decision depends on what the cash does next. Proceeds that buy another rental where coverage clears on its own merits make the strongest case. Proceeds that cover a shortfall elsewhere in the portfolio deserve a harder look, because the new, larger payment lowers coverage on the pool.
Pre-Application Checklist
Gather these before asking for a quote:
- A current lease or rent schedule for every property
- The credit profile of each guarantor
- Documented reserves, sized against about 6 months of PITIA (about 9 months above $1,500,000)
- Payoff figures for every loan you plan to retire
- Title and entity details, confirmed to match
- Insurance and tax figures for each property
- A short list of properties you may sell, so release terms get negotiated up front

Frequently Asked Questions
Does one strong property cover for a weak one?
Within limits, yes. Coverage is measured on the pool, so stronger properties can offset weaker ones, provided the blend clears the floor. Some lenders also look at individual doors. A property that sits well below 1.00 can still be a drag when underwriting tests the pooled coverage, the leverage, and the terms.
Why is my net cash so much lower than my equity?
Payoffs come out first, then closing costs and funded escrows. Because the new loan is capped at a share of value, existing debt consumes most of that space. The leftover figure is net proceeds, and it can be a fraction of the gross equity you calculated.
Can I pull cash out right after buying a property?
Generally not on a full basis. Seasoning of about six months from the deed recording is the common expectation, and inside the first year a cost-basis cap also limits the loan.
Is it better to pool everything or use separate loans?
It depends on the mix. Pooling helps when one property is weaker than the rest and the blend still clears the floor. Separate notes isolate risk and keep exits simple, which can matter more if you expect to sell. For two or three properties, individual loans are usually the practical route.
Does my salary change how big the loan can be?
No. Wages do not enter the sizing on DSCR files, which qualify primarily on property-level rental income covering the payment, subject to lender guidelines. Personal finances still matter for credit, reserves, and any personal guarantee on recourse structures.
