The Quick Read: A balloon on a pooled rental loan is paid off by a new loan that is fully re-underwritten, and empty doors change the rent that new loan will credit. The refinance can still work, but only if pooled coverage on lender-accepted rent and the leverage cap both clear.
- The new lender credits rent it can support, not the rent you had at the original closing.
- Vacant doors usually run on the appraiser’s market-rent opinion, and leverage or terms may adjust.
- Pooled coverage lets strong doors offset weak ones, up to a point.
- Both gates apply at once: coverage on the pool and maximum leverage against appraised value.
- The balloon date is fixed. Vacancies that land in the final stretch cost the most.
Most investors who hold a balloon note think about the payoff date late. By then a few units have turned over, one door is mid-rehab, and the old approval is worth nothing. This piece walks through how a replacement file is built when vacancies are in the pool, what the structure options are, and where the usual rules break. Lendmire is a broker that arranges these loans through select lenders in its wholesale network, so the view here comes from watching many lenders’ guidelines side by side.
What Is a Portfolio Balloon, and Why Does It Force a Refinance?
A balloon note amortizes on one schedule but comes due on a shorter one, leaving a large principal balance at maturity. The CFPB’s balloon payment explainer notes that balloon loans commonly run 5 to 10 years, against 15 to 30 for traditional mortgages, and that the final payment is generally more than twice the average monthly payment.
On-time payments do not remove the balloon. The balance is due. Your options at maturity are a new loan, a sale, or cash.
The same CFPB page says a borrower may be able to refinance before the balloon is due, but may not be able to if property value or finances decline. That is the honest frame for vacancies. Nothing obligates the old lender to roll the note. The replacement is a new transaction, and the new lender tests today’s file.
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.
Key Terms Defined
Balloon payment: the large remaining balance due in one payment when a shorter-term loan matures.
Pooled coverage: total credited rent across every property in the loan, divided by total monthly debt service for the whole pool.
Credited rent: the rent a lender will count for a door, generally the lower of the lease and the appraiser’s market rent, or market rent alone when the door is vacant.
PITIA: principal, interest, taxes, insurance, and any association dues, the debt-service side of the coverage ratio.
Cross-collateralization: several properties securing one note, so a problem at one door can touch the whole loan.
Release price: what the lender requires to free one property from the pool. It runs above that property’s allocated balance.
How Does Underwriting Re-Test the Pool When Doors Are Empty?
The new lender rebuilds coverage from scratch. It adds up the rent it will credit on each door, divides by total PITIA, and compares the result to the program floor. A vacant door does not automatically count as zero. It also does not count at your old lease rent.
Here is the sequence a replacement file follows.
1. Map the maturity. Read the old note for the maturity date, the amortization used for the payment, prepayment terms, and any release or cross-default language. Balloon notes often pair a long amortization with a short term.
2. Re-run the pool. Credited rent across all doors, over total PITIA. A strong door can carry a weak one. A vacant door drags the blend down.
3. Assign rent per door. Leased doors generally credit the lower of the lease and the appraiser’s market rent. Vacant doors rely on the appraiser’s market-rent opinion. Appraisers document that opinion on rent schedule forms. Fannie Mae’s forms list names Form 1007 for one-unit properties and Form 1025 for two-to-four units. Those are borrowed appraisal forms only. DSCR loans are not agency loans.
4. Order valuations. Each property is appraised for value and rent. Leverage then runs against appraised value, so a value shortfall means a paydown or cash to close.
5. Run both gates together. Pooled coverage and maximum leverage must both clear. Empty doors can fail either one, because lower credited rent cuts the supportable loan, and some programs also trim leverage on unleased collateral. The size of that trim varies by program.
6. Collect the file. Expect entity documents, guarantor credit and ID, insurance, reserves documentation, a payoff statement from the old lender, and a lease or rent roll for each leased door.
7. Pay off and restart the clocks. The old note is retired. The new note carries its own term, interest-only option, and prepayment schedule.
One point catches people. Clearing 1.00 is not the same as positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside it.
Which Structures Can Replace a Portfolio Balloon?
Two portfolio structures come up most often in the network, and they behave differently.
The first is a 30-year portfolio DSCR loan. It puts 2 to 20 properties under one note, for loan sizes of roughly $300,000 to $5,000,000, with larger balances on review. Leverage runs up to 80% of value on a purchase or rate-and-term refinance, and the coverage floor is 1.00 measured on the pool. Rates can be fixed or adjustable, there is a 30-year term on a 30-year schedule, and an interest-only period is available. Property types include single-family, 2-4 unit, condo, and townhome. Cash-out on any portfolio loan stays at or below 75% of pooled value. All of this is subject to lender guidelines.
The second is a rental portfolio term loan. It is built for five or more rental properties or units under one loan, from roughly $500,000 up to $50,000,000, with larger balances on review. Leverage runs up to 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 non-recourse looks to the real estate with carve-outs for items like fraud and bankruptcy. Prepayment is yield maintenance. Reserves are held for taxes, insurance, and capital expenditures, and properties in several markets can sit under one loan.
That second structure is itself a balloon. Replacing one balloon with another only moves the cliff. If the plan is to stop facing maturity dates, the 30-year fully amortizing portfolio loan removes the cliff. Spreading a balloon balance over a 30-year schedule also lowers the payment per dollar borrowed, which can lift coverage without any rent change. That is arithmetic, not a program rule.
| Feature | 30-year portfolio DSCR loan | Rental portfolio term loan |
|---|---|---|
| Properties | 2 to 20 | 5 or more |
| Loan size | $300,000 to $5,000,000 | $500,000 to $50,000,000 |
| Leverage cap | Up to 80% (purchase, rate-and-term) | Up to 75% |
| Term | 30-year fixed or adjustable | 3, 5, 7, or 10-year fixed |
| Balloon at maturity | No | Yes |
| Prepayment | Per loan documents | Yield maintenance |

What Rent Counts on a Vacant Door Versus a Leased One?
A leased door is credited at the lower of the signed lease and the appraiser’s market rent. A lease above market does not raise the number. A lease below market caps it.
A vacant door depends on the appraiser’s market-rent opinion. Across our wholesale network, most programs still allow a vacant door into the pool on that basis. Some trim leverage on unleased collateral or want the unit lease-ready. Some want a lease signed before closing. These differences are program-set, and the exact trim is not something to assume.
A rental below 1.00 coverage can sit in a pool because underwriting tests pooled coverage, leverage, and terms rather than each rental alone. It is a pooled-coverage fact, not a separate program.
Not every vacant door is equal. A door that is clean, insured, and market-listed is a rent question. A door mid-rehab, with open permits or no working systems, is a property-eligibility question, and the market-rent opinion will not fix it. Long vacancy also raises questions about marketability and occupancy history.
Appraisal timing matters here. If the market-rent opinion lands before a lease-up, you are stuck with it. If you sign leases first, the lower of lease and market rent governs. Sequence the leases ahead of the appraisal order when a door is close to leasing.
Triage: How Many Doors Are Empty?
Run the pool two ways before you apply: as it stands today, and with every vacant door at market rent. The gap between those two results tells you the path.
| Situation | Likely path | First move |
|---|---|---|
| One door empty, pool still clears | Refinance as is | Get a market-rent opinion on that door |
| Several empty, pool is borderline | Lease up first | Sign leases before the appraisal order |
| One weak door drags the pool | Drop it or pay down | Ask about release terms |
| Large share empty or rehab unfinished | Not ready for a DSCR file | Extend, bridge, or sell |
| Value came in short | Paydown or cash to close | Price the shortfall early |
A weak door can also sit under a blanket note and trip a cross-default or release clause on the old loan. Check the old documents before you move one property.
What Are the Options If Coverage Falls Short?
You have six moves. Each fixes a different problem.
| Option | What it fixes | Main risk |
|---|---|---|
| Lease up | Credited rent | Does not fix value shortfall |
| Paydown | Leverage and coverage | Uses cash and reserves |
| Release or drop a door | Pool drag | Release price runs above allocated balance |
| Split the pool | Isolates weak doors | More notes, more files |
| Extend the old note | Time | Not guaranteed, may cost fees |
| Sell a property | Debt and leverage | Remaining pool must still cover |
A larger down payment or paydown lowers the monthly 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.
Selling one door out of the pool follows the loan documents and the lender’s release terms, and the remaining pool must still cover its own debt service.
Do not force a DSCR file while doors are empty or rehab is unfinished. Extension, a bridge, a partial sale, or a paydown are real alternatives. Lender behavior at maturity is also market-dependent. The CFPB page above is clear that a refinance can be unavailable when value or finances decline.
Where Does the General Rule Break?
Pooled coverage versus per-door. A blanket note blends the test. Separate notes test each door alone. Blending helps the weak door and hurts the strong one’s cushion, so choose deliberately.
Prepayment on the old note. If you refinance early, the cost can be the biggest line in the decision. Read the old note before assuming a refinance pays off. Breakeven math belongs in the plan.
Mixed collateral. The pool only works if every door is eligible. Owner-occupied property, mobile homes, co-ops, mixed-use, and commercial property are ineligible in the pool. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network’s DSCR programs.
Credit and reserves. Credit floors start around 640 on portfolio structures, and 680 or 720 apply on some. Reserves vary by lender, leverage, loan size, and transaction type, commonly around 6 months of PITIA, stepping up to about 9 months on loans above $1,500,000. A special-purpose entity, typically an LLC, is required on some structures, subject to lender program requirements. Recourse loans carry a personal guarantee.
Cash-out. Cash-out on a portfolio never exceeds 75% of pooled value. Inside the first six months of ownership, seasoning rules cap the amount.
Vacancy-heavy exits. If a majority of doors are empty, a bridge or sale is often the cleaner answer.
What Does the Countdown Look Like?
Start early. A balloon is a fixed date and your leverage over it shrinks as it approaches. Here is a practical order.
1. About 12 months out. Pull the old note. Note the maturity, prepayment, and release terms. Run pooled coverage with vacant doors at market rent.
2. About 9 months out. Start leasing vacant doors. Fix anything that makes a unit ineligible or unrentable.
3. About 6 months out. Compare structures with a broker. Decide between the pooled and per-door approach. Line up reserves documentation.
4. About 3 months out. Get leases signed, then order appraisals. Collect entity documents, insurance, and the rent roll.
5. Final stretch. Request the payoff statement and reconcile it against the new file. If the file is not ready, talk to the existing lender about an extension while you still have time.
Some investors test the refinance market well ahead of maturity, learn why lenders pass, and retry with time to fix the problems. That is sound practice. Do not rely on a lender extending a note that you have not discussed with them.
What Goes in the File?
Lenders see fewer gaps when these are ready on day one.
- Entity documents and operating agreement
- Guarantor credit authorization and ID
- A property schedule with addresses, type, and unit count
- Leases for every leased door and a current rent roll
- Evidence for vacant doors, such as listings and condition notes
- Insurance for each property
- Payoff statement from the old lender
- Reserves documentation
- The old note and any release or cross-default provisions
Mistakes That Derail These Files
Assuming a rollover. An extension is a negotiation, not a right.
Applying while doors are empty. Lease first when a lease is close, then order the appraisal.
Ignoring prepayment terms. Early payoff on the old note can eat the benefit.
Equating coverage with cash flow. Clearing the ratio says rent covers PITIA. It says nothing about repairs, turnover, or management.
Using a commercial benchmark. Published coverage benchmarks from commercial lending contexts do not map to non-QM programs. DSCR minimums vary, and 1.00 is where select programs start, not a universal standard. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
Credit scores also matter across programs. A 620 floor exists in parts of the network, most programs want around 660, and 700 or higher unlocks stronger leverage tiers. Those apply to single-property files. Portfolio structures carry the credit floors listed above. For the full program picture, see the complete DSCR loans guide.
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
Can I refinance a portfolio balloon if some units are vacant?
Often, yes, but it depends on pooled coverage. Vacant doors usually run on the appraiser’s market rent, and a few programs trim leverage or want lease-up on unleased collateral. The pooled ratio and the leverage cap both have to clear, subject to lender guidelines.
Will my current lender extend the balloon?
Not as a matter of right. A refinance may be unavailable if value or finances decline, and extension is a negotiation. Raise it early, and keep a replacement loan in parallel.
Does a signed lease above market raise my coverage?
No. Lenders generally credit the lower of the lease and the appraiser’s market rent. A lease above market is capped at market, and a lease below market sets the number.
Does clearing 1.00 mean I’m cash flowing?
No. The ratio compares rent to PITIA only. Vacancy, repairs, management, utilities, and capex sit outside it, so keep your own cash-flow model alongside the lender’s number.
Should I replace the balloon with another balloon?
Only if you accept another maturity date. The 30-year portfolio DSCR loan has no balloon, while the rental portfolio term loan does. Weigh that against leverage, loan size, and prepayment terms.
