The Quick Read: A portfolio DSCR loan counts the lower of the signed lease and the appraiser’s market rent on each property, then pools those counted rents against the pooled monthly payment. A family lease below market shrinks its own door’s contribution, and a lease above market earns no extra credit. Related-party tenants also face an eligibility screen before any math happens.
- The lower figure governs, door by door, before the rents are pooled.
- A pooled test lets stronger properties offset weaker ones, but only if every property is eligible.
- A tenant who lives in the borrower’s household is an occupancy problem, not a rent problem.
- A discounted family lease costs you pooled cushion for as long as it runs.
- Clearing 1.00 coverage is not the same as positive cash flow.
Say you own four rentals and one of them is leased to your sister at a friendly price. You want to refinance all four into one loan. The lender will not ask whether you love your sister. It will ask what rent the property can be counted for and whether the lease is real. This guide walks through that test step by step.
What Does a Portfolio DSCR Loan Actually Test?
A portfolio DSCR loan, also called a blanket or cross-collateralized loan, is one note secured by several rentals. The lender adds the counted rent from every property and divides it by the combined monthly payment. The result is the pooled coverage ratio, and it has to clear the program’s floor.
That payment is PITIA, which stands for principal, interest, taxes, insurance, and any association dues. DSCR itself is the debt service coverage ratio: counted rent divided by PITIA. Most single-property DSCR programs we place files with start at 1.00. A portfolio file works the same way, only the numerator and denominator cover the whole pool.
The word “portfolio” gets used loosely. A bank also uses it for a loan it keeps on its own books instead of selling. That is a different sense of the word. Here it means one note over several properties. For a refresher on the basics, see our complete DSCR loans guide.
Across our wholesale network, two structures matter here:
- The 30-year portfolio DSCR loan covers 2 to 20 properties under one note. Loan sizes typically run from $300,000 to $5,000,000, with larger balances on review. Leverage goes up to 80% of value on a purchase or a rate-and-term refinance. The coverage floor of 1.00 is measured on the pool. Interest-only periods are available. Eligible property types are single-family, 2-4 unit, condo, and townhome.
- The rental portfolio term loan covers five or more rental properties or units under one loan. Loan sizes typically run from $500,000 to $50,000,000, with 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 both recourse and non-recourse versions exist. A non-recourse loan looks to the real estate, with recourse limited to carve-outs such as fraud and bankruptcy.
Every figure above is a program ceiling or floor, not a quote. Terms vary by lender and file, and all of it is subject to lender guidelines.
Key Terms Defined
Market rent: the monthly rent an appraiser concludes a property would earn from a new, unrelated tenant.
Counted rent: the rent figure the lender actually uses in the ratio, which is usually the lower of the lease and market rent.
Pooled coverage: the combined counted rent of all properties divided by their combined PITIA.
Related party: a tenant with a personal or business tie to the borrower, such as a parent, sibling, or family-owned company.
Arm’s-length lease: a lease on terms two unrelated parties would accept, which is the standard a lender uses to judge a related-party lease.
Lower-of rule: the practice of counting the smaller of the lease and market rent. This is a program convention. No federal rule sets it, and a few programs weigh the signed lease more heavily.
Who Sets the Market Rent Figure?
The appraiser sets it, not you and not the lender. For one-unit properties, appraisers use the Single-Family Comparable Rent Schedule, known as Form 1007. For two to four units, they use the Small Residential Income Property Appraisal Report, Form 1025. Fannie Mae’s forms index lists both. The Selling Guide requires the 1007 when an agency loan is reviewed for a one-unit investment property on rental income. DSCR loans are not agency loans. The forms are borrowed formats, not DSCR rules.
The 1007 compares the subject to three rentals on monthly rent. McKissock, an appraiser-education provider, notes that the lender makes the final call on income. It also says nightly short-term rates cannot simply be multiplied by 30. The lender weighs the appraiser’s opinion against documents such as the lease.
Here is what the appraiser does not do. The appraiser does not grade your lease or decide whether your sister’s price is fair. The appraiser gives an opinion of what the property would rent for. The lender compares your lease to that opinion.
How Does the Lower-Of Test Treat a Family Lease?
The lower figure counts. A lease below market becomes the ceiling, a lease at market is counted as is, and a lease above market earns no credit for the excess.
| Lease vs. appraisal | Counted rent | What it means for you |
|---|---|---|
| Below market | The lease | The discount lowers your ratio |
| At market | Either (they match) | No penalty |
| Above market | Market rent | Extra rent buys no extra loan |
| Vacant | Market rent only | The appraisal carries the file |
An investor sometimes assumes a bigger lease helps. It does not. Paying more rent does not buy a bigger loan. This logic also explains why a month-to-month tenancy with little term left often gets replaced by market rent, since there is little lease left to rely on.
Lendmire’s piece How the Lower of Lease and Market Rent Is Applied on a DSCR Portfolio Loan goes deeper on this specific test.
Eligibility Comes Before Arithmetic
Before the lender computes anything, it asks who lives in the property. The rent math does not change with the tenant’s last name. The scrutiny of the paperwork does.
| Tenant | Typical treatment |
|---|---|
| Borrower’s own household | Owner occupancy; not eligible |
| Relative in a separate household | A tenant question; closer review |
| Relative’s business | Related party; arm’s-length proof |
| Relative paying nothing | No lease income to count |
Owner-occupied property is ineligible in the pool, so a tenant who is part of your household ends the discussion before the rent comes up. A relative in a separate household is a tenant question. Some programs bar it, some allow it with closer review, and some are silent. Exact treatment depends on the program and lender. A relative living rent-free gives the lender no rent to count. The appraisal figure may still support a vacant-style rent number, but expect questions about occupancy.
Calling a lease “market rate” does not cure an occupancy problem. A payment history does not either. If the person really lives in your household, the lender sees owner occupancy. Do not plan around hoping nobody asks.
The same logic applies to other cases. Related-party leases are common, and many files work fine. What fails is the file that hides the relationship.
How Does the Pool Change the Math?
The pool applies the lower-of choice property by property first, then adds the results. A discounted family lease therefore shrinks only its own door’s contribution.
Run the numbers on a modeled pool of three rentals. Assume each has the same monthly obligation. Assume the appraiser’s market rent covers that obligation at 1.25x, 1.20x, and 1.20x on the three doors. These are illustrative inputs, not market data.
Now say the second door is the family lease, and the signed rent covers its obligation only 0.90x. The lender counts 0.90x for that door. The pooled ratio is the three counted coverages averaged, since the obligations are equal: (1.25 + 0.90 + 1.20) ÷ 3, or about 1.12x. Had the lease sat at market, the pool would have shown about 1.22x. The discount cost roughly 0.10x of cushion, and the file still clears 1.00.
A thinner pool tells a different story. Assume market coverage of 1.05x, 1.00x, and 1.00x, with the family door’s lease at 0.70x. The pooled ratio becomes (1.05 + 1.00 + 0.70) ÷ 3, about 0.92x. That misses the floor. At market rent the same pool would have shown about 1.02x. One discounted door turned a passing pool into a failing one.
A rental below 1.00 coverage can sit inside a pool, because underwriting tests the pooled coverage, the leverage, and the terms. That is a pooled-coverage fact. It is not a separate low-coverage program. The pool as a whole still has to clear its floor.
A forgiving pool also does not excuse a property-level problem. Every property still needs a lease or an appraiser-supported market rent. A property that is ineligible, such as one the borrower occupies, is not rescued by strong neighbors in the pool. Some lenders also check each asset individually.
What One Weak Lease Does to the Whole Note
On a blanket loan, the properties are collateral for the same debt. One weak door affects the whole file, in three ways.
It lowers proceeds. Lower counted rent can mean a smaller loan, or a file that no longer clears the pooled floor.
It follows the loan after closing. 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. After a release, the remaining portfolio must still cover its debt service. If the family tenancy ends or changes, the same pooled test applies to what remains.
It can limit a cash-out. A cash-out on a portfolio loan never goes above 75% of the pooled value. 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.
The credit floor on the portfolio programs is typically 640, with 680 or 720 on some structures. Some structures require a special-purpose entity, typically an LLC, depending on program guidelines. Recourse loans carry a personal guarantee.
What Proof Does a Related-Party Lease Need?
A lender wants the lease to look like one a stranger would sign and pay. The strongest file gives it an easy yes.
| Weak file | Strong file |
|---|---|
| Handshake or expired lease | Signed, current lease |
| Cash payments, no trail | Bank statements from the tenant’s own funds |
| Rent unrelated to comps | Rent at or near the appraiser’s figure |
| Relationship left unexplained | Relationship disclosed up front |
Add the rent schedule, a rent roll for the whole pool, and any renewal documents. Disclose the relationship on day one. A file that surfaces it late looks worse than a file that opens with it.
What Can You Do About a Below-Market Family Lease?
You have several options, and each one trades something. Compare them before the appraisal, not after.
| Option | Effect on ratio | Cost to you |
|---|---|---|
| Renew at documented market rent | Raises the door to market | Your relative pays more |
| Re-lease to an unrelated tenant | Raises the door to market | Turnover, vacancy risk |
| Leave the door out of the pool | Removes its drag | Separate loan for that door |
| Put more down | Lowers the payment; raises the ratio | More cash into the deal |
| Finance that door alone | Tested on its own | Single-property terms apply |
A larger down payment lowers the payment and can lift the ratio without touching rent. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Timing matters. If you plan to renew a family lease at market rent, do it before the appraisal. If the appraiser’s rent comes in below your own estimate, the lower number still governs. Single-property DSCR loans can go below 1.00 coverage through select lenders in the network, with leverage and terms adjusted. That is a different path from the pooled floor.
The honest toss-up is whether to carve the family door out. Leaving it out cleans up the pool but costs you a separate loan. Keeping it in saves paperwork but charges you cushion on every other property. The answer usually follows how much cushion the rest of the pool has.
Where the General Rule Breaks
Several situations bend the standard approach.
- Short-term rentals in the pool. The 1007 documents monthly long-term rent, not nightly income, and the lender decides what counts. Short-term rental rules vary by city, county, HOA, and property type, so confirm local rules before relying on projected rental income.
- Voucher-subsidized units. Practitioners often find that substituting market rent for a subsidized lease is not accepted. Ask before you assume.
- Rent concessions. The 1007 asks about concessions in the comparables, so free-rent deals can affect the market figure.
- Rent-controlled units. Form 1025 asks whether the property is subject to rent control, which can cap the rent a unit can earn.
- Five or more units. Small multifamily is eligible only inside the rental portfolio term loan. It is not eligible on the 30-year portfolio structure or on a single-property DSCR loan.
- Rent-by-the-room setups. Lenders generally cap the income at the single-family market rent and ignore higher actual rent.
Manufactured and mobile homes are not reviewable on any of these programs.
Also keep coverage and cash flow separate. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside the calculation, so clearing 1.00 does not mean the portfolio cash-flows. A discounted family lease can look fine on the ratio while the real return is thinner.
Frequently Asked Questions
Can my parent or sibling be the tenant in a portfolio DSCR loan?
Often yes, if they live in a separate household and the lease is current and documented. Programs differ, and some bar it. Expect closer review, a signed lease, and a payment trail from the tenant’s own funds.
Does owning the property through an LLC solve a family-tenant issue?
No. An LLC changes how title is held, not who occupies the property. Entity requirements vary by structure and are subject to lender program eligibility. A household member living there is still owner occupancy.
What if the appraisal comes in below my own rent estimate?
The appraisal figure governs when it is lower than the lease. You can renew at a documented figure that matches the appraiser’s evidence, or discuss the comps with the lender. You cannot count rent the appraiser does not support.
Should I exclude the family-leased property from the pool?
It depends on how much cushion the rest of the pool has. If the pooled ratio clears with the discounted lease counted, leaving it in simplifies the file. If it does not, carving the door out or re-leasing at market may be cleaner.
Is a family-owned business a different case from a relative?
It is still a related party, so the arm’s-length question applies. The lender will look for a signed lease, a payment trail, and rent near the appraiser’s figure. The business must be separate from the borrower’s household.
