The Quick Read: A DSCR portfolio loan does not carry an older cheap mortgage forward; it pays that mortgage off, retires the old note and its rate, and tests the pooled rent of every property against the payment on one new loan, so the old rate plays no part in qualification and matters only when you decide which properties to include.
- The old loan is paid off at closing, and its rate and remaining term do not transfer.
- Coverage is measured on the pool: combined rent against the combined payment of the new note.
- Giving up a cheap rate is a real cost, so the decision is keep, replace, or split.
- Clearing the coverage test is not the same as positive cash flow after repairs, vacancy, and management.
- Everything here is subject to lender guidelines, credit approval, and property review.
“Older” can mean two things. Some investors mean a seasoned loan, one held for years at a below-market rate. Others have typed it as a question about the borrower’s age. This article covers the first meaning: what happens to those long-held, inexpensive mortgages when an investor pools rentals under a single DSCR portfolio loan.
What a DSCR Portfolio Loan Actually Is
A DSCR portfolio loan, also called a blanket loan, puts one mortgage on two or more rental properties. Every property secures the whole balance. The lender looks at the rent the pool produces against the debt service on the new note, not at the borrower’s personal income. A portfolio loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
Across Lendmire’s wholesale network there are two main structures. The first is a 30-year portfolio loan for two to 20 rentals. Loan sizes typically run from $300,000 to $5,000,000, with larger balances reviewed individually. Leverage goes up to 80% of value on a purchase or rate-and-term refinance. The coverage floor is 1.00 on the pooled numbers, and an interest-only period is available. Eligible property types include single-family, two-to-four unit, condo, and townhome.
The second is a rental portfolio term loan for five or more properties or units. Balances typically run from $500,000 to $50,000,000, with leverage up to 75% of value. Terms are fixed at three, five, seven, or ten years with a balloon at maturity. Recourse and non-recourse versions both exist. A non-recourse loan looks to the real estate, with recourse limited to carve-outs such as fraud and bankruptcy. Small multifamily is eligible only on this term structure.
These are program ceilings and floors, not quotes. Each file is underwritten individually. For the broader picture, the complete DSCR loans guide walks through how single-property and pooled programs differ.
How the Underwriting Treats an Existing Cheap Mortgage
The short answer is that it doesn’t treat it as anything. The old note is paid off, and the new note replaces it. Here is the sequence.
1. The pool is assembled. Each property is appraised, and the pooled value caps the total loan.
2. Each old lien is documented. The file needs a payoff statement for every existing mortgage so the old notes can be retired.
3. Old-loan exit costs are checked. A conventional old loan usually carries no prepayment penalty. A prior DSCR or portfolio loan may carry one, and it is paid at payoff.
4. Rent is pooled. Every property needs a lease or an appraiser-supported market rent.
5. The new payment is built. Principal, interest, taxes, insurance, and association dues are combined for the new note.
6. Coverage is tested on the pool. Pooled rent is divided by pooled debt service. Stronger properties can offset weaker ones.
Step six is where the cheap loans disappear. Suppose one rental carried a very low payment on its own mortgage. Once pooled, it becomes a share of one larger payment priced for the whole balance. The ratio reflects current-market debt service on the full pool, not a blend of the old payments.
That is why the old rate carries no weight in the test. The lender is not asking what you paid before. It is asking whether the pool’s rent covers the new note.
A Worked Example With Modeled Ratios
Picture a hypothetical pool of four rentals. Two have older, inexpensive mortgages, and two were financed more recently at higher cost. On their own old loans, the cheap pair might each show coverage around 1.4x or better. The newer pair might sit nearer 1.05x.
Now pool all four under one new note. The new payment is built on the full combined balance, so the cheap properties lose their advantage. In this modeled case the pooled coverage lands near 1.10x. It clears a 1.00 floor, though without much margin. These ratios are illustrative assumptions, not market data.
Run it a second way. Leave the two cheap-loan properties out and pool only the two newer ones. The sub-pool’s coverage reflects just those two rents against just their new payment, and the cheap loans stay in place untouched. This is a structuring choice, and it tends to work when the two newer properties can pass on their own rents, so the cheap properties’ rent is not needed for the pool to qualify, and the investor values keeping the old loans in place.
Where a weak pool fails, the usual fixes are lease renewals at current rents, a smaller loan, or extra reserves. Rents set years ago are often below market, which drags down pooled coverage on exactly the properties that carry a more affordable debt.
Keep, Replace, or Split: A Decision Table
| Old loan situation | Likely path | What to check | Main drawback |
|---|---|---|---|
| Cheap loan, no cash need | Keep it | Is the property needed for pool coverage? | Separate servicing |
| Cheap loan, cash need | Split or second lien | Lien position, lender consent | Added debt layer |
| Prior loan with prepay window | Wait or negotiate | Remaining penalty period | Exit cost at payoff |
| Strong property, weak pool | Leave it out | Pooled coverage without it | Weak assets stand alone |
None of these paths is universally right. The deciding variable is what the investor does with the flexibility. If the goal is to pull equity to buy another rental, giving up one cheap rate may be worth it. If the goal is simply tidier servicing, it usually isn’t.
The Cost of Giving Up the Old Rate
Treat the old rate as an asset you are selling. Before pooling, weigh four things.
- What you lose: the spread between the old payment and the new payment on that balance, for the remaining term.
- What you gain: one closing, one servicing relationship, access to equity, and release terms that may let you sell one property later.
- New exit costs: the new note brings its own prepayment schedule. On the network’s term loan, prepayment runs on a yield-maintenance basis, typically 54 months on the five-year note and 114 months on the ten-year note.
- New risks: cross-collateralization means one default or a vacancy spike can affect the whole pool.
The lock-in effect is real and widely felt. Scotsman Guide reports that 35% of homeowners with sub-6% mortgages say they refuse to give up their rates. That figure covers homeowners generally, not rental investors, but the instinct is the same. A low fixed payment is hard to replace.
Also worth knowing: consolidating into a portfolio loan does not reset the conventional financed-property count. Investors hoping to free up conventional capacity by pooling usually find it doesn’t work that way.
Alternatives That Keep the Cheap Loan
Some investors never pool their more affordable properties. A lender commenter in a BiggerPockets discussion of cash-out refinancing a rental suggests leaving a very low first mortgage in place and adding a second-position loan for the equity. That is one investor-side view, not a rule, and it has trade-offs. The second lender must accept the lien position, and the layered debt complicates later refinances.
A split portfolio is the other common route. Put the higher-cost or weaker-performing properties in the blanket loan and leave the cheap-loan properties out. This preserves the old rate and still consolidates the rest. It also means the pool must pass on its own rents, since the excluded properties no longer help the ratio.
Cash-out is its own decision. On a portfolio loan, cash-out never exceeds 75% of the pooled value, and the seasoning rules cap proceeds in the first months of ownership.
Cross-Collateral and Release Mechanics
Cross-collateralization is the defining feature of a blanket loan, and it cuts both ways. A strong, low-leverage property can end up securing a weaker one. If any asset in the pool underperforms, the lender has a claim on all of them.
Release terms decide what happens when you sell one property. Partial releases, substitutions, and the sale of a single property follow the loan documents and the lender’s release terms. The release price runs above the property’s allocated balance, and the remaining portfolio must still cover its debt service afterward. Without a release clause, selling one property can mean paying off the entire note. Negotiate those terms before closing, not after.
A rental that falls below 1.00 on its own can still sit inside a pool. In that case underwriting tests the pooled coverage, the leverage and the terms. The property is not judged alone.
Prepayment Penalties on the Loans You Retire
An older conventional mortgage typically has no prepayment penalty, so paying it off costs nothing beyond the lost rate. An older DSCR or portfolio note may be different. Step-down schedules reduce the penalty each year. Flat or longer schedules usually trade a higher exit cost for better pricing. Some structures never reach zero inside the term, and yield-maintenance structures can cost far more than a step-down.
Before pooling, read the prepayment clause on every note you plan to retire. A penalty still running on one loan can change which properties belong in the pool and when.
Where the General Rule Breaks
A few situations bend the standard “paid off and replaced” picture.
Due-on-sale and entity transfers. A due-on-sale clause is a contractual right of the lender, not a statute, as CREUniversity explains. Moving title into an LLC can still trigger it on an old loan that stays in place. Refinancing that loan out of the picture removes the issue, but title sequencing matters when any old loan remains. Entity-titled borrowing is subject to lender program eligibility, and a special-purpose entity is required on some structures. Sequence it with an attorney.
Ineligible property types. Owner-occupied property, co-ops, mixed-use, and commercial property are not eligible in the pool. Manufactured and mobile homes are not reviewable on these programs, and log homes and barndominiums are not offered either.
Multi-market pools. On the rental portfolio term loan, properties in several markets can sit under one loan. That helps diversification, but it also widens the cross-collateral exposure.
Credit and entity requirements. The portfolio programs set a credit floor of 640, with 680 or 720 on some structures. Recourse loans carry a personal guarantee.
Portfolio Loan, Separate Loans, or Keep What You Have
| Factor | Portfolio loan | Separate DSCR loans | Keep old loans |
|---|---|---|---|
| Review basis | Pooled rent | Each property alone | Already in place |
| Closings | One | One per property | None |
| Risk linkage | Cross-collateral | Isolated | Isolated |
| Selling one | Release terms apply | Pay off that loan | Pay off that loan |
| Old rate | Given up | Given up | Preserved |
Neither column wins everywhere. Separate loans cost more in closings but keep risk isolated. Keeping the old loans costs nothing in rate but limits access to equity.
What Coverage Does and Doesn’t Tell You
DSCR compares rent to PITIA only. That means principal, interest, taxes, insurance, and association dues. Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capex all sit outside the calculation. A pool that passes at 1.10x can still lose money in a bad year. Size the cushion yourself, and treat the lender’s test as a floor for qualification, not a profit forecast.
The same applies to leverage. A larger down payment lowers the payment and can lift coverage, but it does not erase leverage caps, credit floors, reserve rules, or property eligibility. Reserves vary by lender, leverage, and loan size. On the term loan, reserves are held for taxes, insurance, and capital expenditures. Tax treatment varies; consult a qualified professional.
Key Terms Defined
Blanket (portfolio) loan: one mortgage that secures two or more properties under a single lien.
Cross-collateralization: every property in the pool secures the whole balance, not just its own share.
Release clause: a loan term that sets the conditions and price for removing one property from the pool.
Yield maintenance: a prepayment structure that charges the lender’s lost interest if you pay off early.
Due-on-sale clause: a contract term that lets a lender demand repayment when the property is transferred.
Seasoned loan: a long-held mortgage, often with a below-market rate.
Frequently Asked Questions
Can I keep a cheap loan and still use a portfolio loan?
Yes, by leaving that property out of the pool. The pooled loan then covers only the properties you include, and those rents alone must pass the coverage test. The cheap loan stays where it is, with its own payment and its own lien.
Does the old rate carry over into the portfolio loan?
No. The old note is paid off and replaced by a new note priced for the whole pool. The coverage test looks only at the new payment, so the old rate has no effect on qualification.
What happens if I sell one property later?
That depends on the release terms in your loan documents. The release price runs above the property’s allocated balance, and the remaining pool must still cover its debt service. Without a release clause, a sale can require paying off the whole note.
Does cash-out change any of this?
Cash-out adds a bigger balance, which can pull pooled coverage down. It is capped at 75% of the pooled value, and the seasoning rules limit proceeds in the first six months of ownership. The cheap-loan trade-off is unchanged.
Do I owe a penalty on the old loan?
Usually not on a conventional note, but it depends on the loan. Prior DSCR or portfolio notes can carry step-down or yield-maintenance penalties that are paid at payoff. Read the prepayment clause on each loan before you pool.
Where This Leaves the Decision
Pool when the benefits you actually need, such as access to equity, one servicing relationship, or release flexibility, are worth more than the rate spread you give up. Leave a property out when its old loan is cheap and the pool still passes without it.
