The Quick Read: Pre-underwriting means running the lender’s own tests on your pool of rentals before you submit: test each property’s rent against its payment, blend the pool, stress it, check reserves and credit, and read the release terms so you know how the loan behaves after you close. You are hunting for the weak property, the missing lease, and the expensive exit while you can still change the pool.
- The 30-year portfolio DSCR loan puts 2 to 20 properties under one note, with a 1.00 coverage floor measured on the whole pool, subject to lender guidelines.
- The rental portfolio term loan is built for five or more rentals or units, with fixed terms that end in a balloon payment.
- Pooled coverage lets strong properties offset weak ones, but each property still needs its own appraisal and a lease or appraiser-supported market rent.
- Clearing 1.00 does not mean positive cash flow, because repairs, vacancy, management, and utilities sit outside the calculation.
- The release price to free one property runs above that property’s allocated balance, and the remaining pool must still cover its debt service.
What a DSCR Portfolio Loan Actually Is
A DSCR portfolio loan is one mortgage secured by several investment properties. People also call it a blanket loan or a portfolio loan. The three words describe different things, and one loan can be all three.
Blanket describes the structure: one note, many properties. Portfolio describes who holds the debt. DSCR describes how the loan is qualified, which is the rent the properties earn measured against the payment they carry. Across the wholesale network Lendmire places files with, the loans are underwritten to the properties first and the borrower second.
Each property keeps its own deed, its own appraisal, and its own rent opinion. The pool math sits on top of that property-level work. It does not replace it.
Two structures cover most of what investors ask about. The 30-year portfolio DSCR loan covers 2 to 20 properties under one note. The rental portfolio term loan covers five or more properties or units, usually with a fixed term and a balloon at maturity. Everything below applies to both unless a section says otherwise.
| Feature | 30-year portfolio DSCR loan | Rental portfolio term loan |
|---|---|---|
| Pool size | 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% |
| Term | 30-year; fixed or adjustable | Fixed 3, 5, 7, or 10 years |
| Guarantee | Per loan documents | Recourse or non-recourse |
These are program ceilings and floors, not quotes. Larger balances are reviewed individually, and everything is subject to lender guidelines. A loan on one rental follows different numbers entirely: typically 75%-80% LTV on a purchase, with a standard loan-size ceiling of $3,000,000.
Eligible property types in the pool are single-family, 2-4 unit, condo, and townhome, with small multifamily added on the term loan. Owner-occupied homes, co-ops, mixed-use, and commercial property are ineligible. Manufactured homes, log homes, and barndominiums are not offered in these programs.
How Underwriting Tests a Pool
A lender runs two passes on a pool. The first is property-level: appraisal, rent evidence, title, and insurance for each asset. The second is pool-level: total rent against total debt service, plus leverage, credit, and reserves.
Coverage is measured on the pooled rents and pooled debt service of the whole portfolio, so stronger properties can offset weaker ones. That is the headline benefit. It is also the reason you should not assume it works the same on every file.
Some lenders in the network apply a floor on the blend alone. Others also look at each property’s standalone coverage. Ask which test applies before you decide which assets to include, because the answer changes who belongs in the pool.
The formula for the pool is plain. Add up gross monthly rent across every property. Add up the full monthly obligation across every property: principal, interest, taxes, insurance, and any association dues. Divide the first total by the second.
Pre-underwriting is a screening step, not an approval. The appraiser’s value, the appraiser’s rent conclusion, lender overlays, and final pricing all arrive after you apply. Your job is to remove every problem you can control.
Step 1: Build the Property Ledger
Start with a one-row-per-property ledger. It is the most useful document in the whole exercise, and most investors have never written one.
| Item | What to gather | Why it matters |
|---|---|---|
| Rent | Lease and rent roll | Drives the numerator |
| Obligation | Taxes, insurance, dues, payoff | Drives the denominator |
| Value | Recent estimate | Sets leverage |
| Ownership | Deed, entity, vesting | Controls eligibility |
| Flags | Vacancy, repairs, stale lease | Predicts conditions |
Fill in the lease status for every unit. One stale or missing lease is the most common thing that slows a pool file, and it is entirely fixable before you apply. A lease that expired and rolled month-to-month needs to be renewed or documented.
Gather current tax bills, insurance declarations, and association statements as you go. Add mortgage payoff statements for anything you are refinancing, and proof of reserves.
Step 2: Settle on One Rent Number Per Property
The rent that counts is the rent a lender can support, not the rent you hope for. Every property needs a lease or an appraiser-supported market rent. Many programs credit the lower of the in-place lease and the appraiser’s market rent, so plan for the lower number.
Appraisers document market rent on standard forms. Form 1007 is the Single-Family Comparable Rent Schedule, used for one-unit properties. Form 1025 covers two to four units, and the blank form shows the appraiser reconciling market rent for each unit. For one-unit properties, the rent schedule is typically paired with the standard appraisal report, while two-to-four-unit properties use the 1025 on its own.
Those are appraisal form names, not DSCR rules. They tell you what the appraiser’s rent evidence will look like, which is all you need for a self-test.
Short-term rentals have no lease comps, so programs generally accept alternatives such as an appraiser’s rental analysis, property-management statements, or bank statements. Lendmire’s piece How to Underwrite an STR Market for DSCR Before You Buy covers that evidence in depth. 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.
Step 3: Run Each Property, Then the Blend
Compute each property’s coverage alone first. Divide its rent by its full monthly obligation. Mark the weakest one. That number tells you what the pool is carrying.
Now run the blend. Picture a three-property pool where the monthly obligations are roughly equal in size. Property A covers its own payment at about 1.40x. Property B covers at about 1.20x. Property C covers at about 0.90x.
The blended coverage lands near 1.17x, which clears a 1.00 pooled floor. Property C would not pass alone. It can sit in the pool, but the pooled coverage, the leverage, and the terms are what underwriting tests, subject to underwriting.
Notice what the blend hides. If the lender also reviews each property, Property C is the file’s problem. If it does not, Property C is still the first asset you will want to sell, and a sale changes the pool you are left with.
Also compute aggregate leverage. Add up the proposed loan against the combined value of all the properties. On a purchase or rate-and-term in the 30-year portfolio DSCR loan, the cap is up to 80% of value, and the rental portfolio term loan caps at up to 75%. A cash-out never exceeds 75% of pooled value, and it never exceeds the structure’s own ceiling. Inside the first six months of ownership, a cost-based cap applies: leverage is limited to 90% of total cost in the first six months and 100% from six to twelve months. A rate-and-term refinance carries no cost restriction.
A bigger 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.
Step 4: Stress the Pool
Stress testing is the step most checklists skip, and it is where a pool shows how fragile it is. Run three changes on your ledger and see what happens to the blend.
- A vacancy. If Property B has no rent for the test, the pool in our example drops to about 0.77x. That is under the 1.00 pooled floor.
- A cost increase. If every obligation rises about 10% from taxes, insurance, or dues, the blend falls to about 1.06x. Still passing, but the cushion is gone.
- Rent at the lower figure. Replace every rent with the lower of the lease and the likely appraised market rent. This is the version a lender will run.
If a single vacancy sinks the pool, you have two options. Build in more cushion before applying, or put that property in a separate note. The same logic applies if your cushion disappears with a modest cost increase.
One more reminder. Coverage compares rent to the full monthly obligation only. A pool that clears 1.00 is not necessarily producing positive cash flow, because repairs, vacancy, management, utilities, and capital expenses are outside the calculation. Keep those in your own cash-on-cash model.
Step 5: Check Reserves, Credit, and Entity
Reserves are cash the lender wants you to hold after closing. Across the network they vary by lender, leverage, loan size, and transaction type. About 6 months of principal, interest, taxes, insurance, and dues is a common expectation, and loans above $1,500,000 typically step up to about 9 months. On the rental portfolio term loan, reserves are held for taxes, insurance, and capital expenditures. Remember that a pool carries the obligations of every property, so the reserve number scales with the size of the whole portfolio.
On credit, portfolio structures typically look for a floor of 640, with 680 or 720 required on some. A single-property DSCR loan can accept lower tiers in parts of the network, so do not carry that assumption over.
Entity matters too. A special-purpose entity, typically an LLC, is required on some structures. The LLC borrows and an individual guarantor usually signs. Several LLCs can share one note when the same people ultimately own them, subject to lender program eligibility. Recourse loans carry a personal guarantee, while non-recourse structures exist on the term loan with carve-outs for fraud and bankruptcy.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage, as America’s Credit Unions explains in its summary of business-purpose lending.
Step 6: Decide What Goes in the Pool
Pool curation is where pre-underwriting pays for itself. You are allowed to leave a property out, and often you should.
| Situation | Typical next move |
|---|---|
| Blend passes, one property is weak | Confirm whether each asset is tested alone |
| Blend is short | Drop the weakest asset or pay down |
| Stale lease on one unit | Renew or document before applying |
| Reserves fall short | Raise cash or reduce the loan amount |
| Wide gap between strong and weak | Split into two notes |
Weak properties can ride on strong ones, but that usually works only to a point. A pool made mostly of one lean asset with a couple of strong ones behind it can fail on the stress test even when the baseline passes.
Think about exit timing as well. If you plan to sell one property within a couple of years, that asset may belong in a separate note, or the release terms need to be favorable. Which brings up the part of the loan that most investors read last.
What Happens When You Sell One Property?
Selling one property from a pool means repaying a portion of the loan, not pocketing the proceeds. Partial releases, substitutions, and the sale of one property out of the pool follow the loan documents and the lender’s release terms. The release price runs above the property’s allocated balance, and the exact terms vary lender by lender.
A release clause exists only if it is written into the note. Without one, there is no right to release, and a sale can trigger the due-on-sale clause on the entire loan. Your options then are a full payoff, a refinance, or holding both properties.
After a release, the lender tests the remaining collateral. The remaining portfolio must still cover its debt service. If you sell the strongest property, the weak ones are left to carry the loan, so model that retest before you apply.
Cross-collateralization cuts the other way as well. Every property secures the whole loan, so trouble with one property can reach the rest. With separate loans, a default affects only that note. That is the main structural trade-off, and it is the price of one closing and one payment. The rental portfolio term loan can even place properties in several markets under one loan, which widens the benefit and the exposure together.
Where the Pool Math Breaks
- Per-property floors. If a lender tests each asset as well as the blend, the strong-carries-weak benefit shrinks.
- Mixed pools. Pools mixing one-unit, 2-4 unit, and short-term-rental assets can be treated differently, and some programs limit property types.
- Interest-only periods. The 30-year portfolio DSCR loan offers an interest-only period, which lowers the qualifying payment and can lift coverage. Confirm how the program counts the payment during that period.
- Prepayment. The rental portfolio term loan carries yield maintenance, a charge for paying off early, so a planned sale or refinance has a cost built in.
- Owner-occupied property. It cannot sit in the pool. If you live in one of your properties, it stays out.
- Short seasoning. A recent purchase can cap a cash-out well below the headline ceiling.
What to Ask the Lender Before You Submit
- Is coverage tested on the blend alone, or on each property too?
- Is a release clause written into the note, and how is the release price set?
- What is the minimum number of properties that must remain after a release?
- Which rent figure is credited: the lease, market rent, or the lower of the two?
- How are reserves measured across the pool?
- Does the interest-only period change the qualifying payment?

Frequently Asked Questions
Can one weak rental sink the whole pool?
It can, depending on how the lender tests. If coverage is measured on the pool alone, a weak property can be offset by stronger ones. If each property is also reviewed, the weak one becomes its own issue. Stress your numbers both ways before you apply.
Can a rental below 1.00 coverage sit in the pool?
Yes, it can sit in the pool. The pooled coverage, the leverage, and the terms are what underwriting tests, subject to underwriting. Programs on a single rental that go below 1.00 are a separate path through select lenders, with leverage and terms adjusted.
Does clearing 1.00 mean the properties make money?
No. Vacancy, repairs, management, utilities, and capital expenses are not in the calculation, so run your own cash-flow model alongside it.
Can I sell one property and keep the loan on the others?
Only if the loan documents include a release clause. You repay a portion of the loan, set at a price above the property’s allocated balance, and the remaining portfolio must still cover its debt service.
Which properties are not allowed in the pool?
Owner-occupied property, co-ops, mixed-use, and commercial property are ineligible, and manufactured homes, log homes, and barndominiums are not offered. Single-family, 2-4 unit, condo, and townhome properties are eligible, and the term loan adds small multifamily.
