The Quick Read: Substitution swaps one pledged rental for a replacement inside a single loan. Release and add takes a property out of the loan through a partial release, then brings a different property in. Which one works depends on what your note allows, what the lender consents to, and whether the leased properties that remain and the new one still clear the coverage and leverage tests.
- Substitution is usually one swap event. Release and add is two events, and each one is underwritten.
- Substitution suits investors who want to keep the pool intact. Release and add suits investors who want to sell a property and grow at the same time.
- A tenant in place helps both paths, because a signed lease is documented rent. The lender still looks at market rent, and a vacancy can stall either path.
- “Release and add” is shorthand, not a standard product name. What you can actually do comes from the loan documents.
- Neither path replaces reading your note before you plan an exit.
Say you hold a package of rentals under one loan, and one property is leased and performing but no longer fits your plan. You can swap it out or release it and add something new. Both paths touch the same tenants, rent roll and lender relationship. They differ in how many times the lender re-tests the file.
This piece referees both options from the broker’s chair. Lendmire is a broker that arranges these loans through select lenders in its wholesale network, across 41 markets including Washington, D.C. The details below come from how those files are structured, and the comparison column describes published industry norms.
Key Terms Defined
Package (pooled) loan: One loan secured by several properties, so all of them stand behind the same debt.
DSCR: Debt service coverage ratio. It compares monthly rent to PITIA, which is principal, interest, taxes, insurance, and any association dues.
Release clause: A note provision that lets you remove one property from the lien after paying an agreed amount, while the loan and the other properties stay in place.
Substitution of collateral: Replacing a pledged property with another one, usually of equal or greater value, with the lender’s consent.
Release and add: Shorthand for releasing one property and then adding a different one. It is not a standardized product, so it depends on what the note permits.
Tenant-occupied: The property has a lease in place and is producing documented rent.
Side-by-Side
The table below uses published industry norms for each structure. Every note is its own contract, so treat it as a map and not a promise.
| Factor | Substitution | Release and Add |
|---|---|---|
| Review basis | Replacement property’s rent vs. its PITIA | Added property, plus the remaining pool |
| Number of events | One swap | Two: release out, then add in |
| Documentation | Lease and market rent on the new property | Payoff and recording, plus new-property file |
| Property types | Replacement must fit program eligibility | Added property must fit program eligibility |
| Entity vesting | Each owning entity signs; guaranties continue | Same, plus any new entity on the added property |
| Lender consent | Typically required, often at the lender’s discretion | Release terms in note; add needs approval |
| Pool coverage risk | Pool re-tested with the new property in | Remaining pool re-tested after the release |
| Reserve expectations | Vary by lender, leverage and loan size | Vary by lender, leverage and loan size |
| Best fit | Keeping the pool intact | Selling one and growing |
The comparison is about structure, so neither column carries a pricing row.
How Each Path Works
Substitution
A substitution clause lets you propose a replacement property. Without that clause, a swap is a negotiated change to the note, not something you are owed.
An SEC-filed collateral substitution agreement shows the general logic. It is a commercial contract, not a DSCR loan, so treat it as an illustration only. It asks for a replacement of equal or greater value, lender approval at the lender’s reasonable discretion, and no default when the request is made. It also puts the lender’s costs on the borrower.
Think of that as the skeleton. The DSCR version adds the rental test: the incoming property must show its own lease and market rent, and its rent must cover its own payment at the level the lender requires. The outgoing property’s rent leaves the pool at the same time.
Release and add
A release clause lets you sell or refinance one property out of the package. You pay a release amount tied to that property, the lien is cleared by a recorded release, and the loan continues on the rest. Release amounts are commonly set above the property’s simple share of the balance, which protects the lender. The exact premium is a note term, so read yours.
The add side is a separate step. A new property joins through a modification of the existing loan, or through new financing. Either way, it is underwritten as a rental in its own right.
When Substitution Is the Better Fit
Substitution fits when the pool as a whole is working and you only want to change one piece. A few patterns point that way.
- The package is performing. The remaining properties are leased, the combined coverage is healthy, and you would rather not disturb that.
- You have a replacement ready. A swap works best when the new property is already identified, leased, and similar in value. The lender’s test is whether it ends up no worse off, so a comparable property moves more smoothly than a stretch.
- You want one consent event. One request, one re-test, and one set of documents is simpler than two.
- You have no use for sale proceeds. If you are not trying to cash out of the property that leaves, there is little reason to run a payoff event.
The tradeoff is dependence on the clause. Where a note has no substitution language, the lender can say no. Lenders also care about the replacement’s quality, so a weaker or vacant incoming property may stall the request.
A good way to picture it is a four-property package where one older duplex is the weakest link. You find a newer duplex with a signed lease and rent in line with the one leaving. The swap keeps the pool’s coverage story close to what it was. The same swap with a vacant replacement is a much harder conversation.
When Release and Add Is the Better Fit
Release and add fits when your goal is to turn one property into cash and put that capital somewhere else. It also fits when the note has a release clause but no substitution clause.
- You want to sell. A release clause lets you sell a leased property and keep the loan. If the note has no such clause, the lender can treat the sale of part of the collateral as a reason to call the whole loan due, which is why the clause matters. The federal due-on-sale statute, 12 U.S.C. § 1701j-3, covers a sale of all or any part of the property. It gives you no right to a partial release, so that right exists only if your note grants it.
- The replacement is not ready. Release and add lets you act on the exit first and shop for the next property afterward. The cost is time with a smaller pool.
- You want a different property type or market. Because the added property is underwritten fresh, it can differ more from the one leaving than a substitution lender would normally accept.
- You want a clean break. After a release, the old property is gone from the lien and the pool is re-tested without it.
The tradeoff is that you create two underwriting events and two sets of documents. If the remaining pool’s coverage dips after the release, the lender may ask for more before you can add anything. That is why the order of the steps matters: releasing first can weaken the pool, while adding first can stretch leverage.
What the Tenant Changes
A tenant in place helps both paths. The reason is simple: the lender wants documented rent, and a signed lease is documented rent. The lender generally works from the lower of the lease rent and the appraiser’s market rent. For a leased property, that means the lease supports the number but does not set it alone.
What lenders typically want on a tenant-occupied property:
- An executed lease for each unit.
- Proof that rent is actually being paid.
- A rent roll on multi-unit buildings.
- An appraisal rent schedule. For one-to-four-unit properties, the appraisal forms commonly used are the 1007 single-family rent schedule and the 1025 small residential income report. DSCR loans are not agency loans, so only the form names carry over, not agency rules. Fannie Mae’s Selling Guide requires the 1007 for its own one-unit investment loans, which is a contrast and not a DSCR rule.
Here is how the tenant shows up in each path.
Substitution. The incoming property needs its own lease and market-rent evidence. If it is month-to-month or vacant, market rent may carry the file by itself, and that usually means a more cautious read. The outgoing tenant’s lease stays with the property, so plan how the handoff affects your rent collection and any notice obligations.
Release and add. The released property’s lease leaves the pool, and the pool’s coverage is re-tested on what remains. The added property then brings its own rent. If the remaining units have vacancy or late payments, that can make the lender hesitate about a release.
Short-term rentals add a wrinkle. Nightly-rate income does not fit a monthly rent schedule, so lenders document it separately.
One point trips people up: a coverage number above 1.00 is not the same as positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation, so a package can clear the test and still be tight in real life.
Where the Network’s Programs Fit In
Whichever path you pick, the property that stays or arrives is still judged against program rules. Across the wholesale network, most purchase files land at 75%–80% LTV on an investment property, and cash-out refinances top out around 75% LTV. Coverage of 1.00 is where select programs start, while a separate select-lender path goes below 1.00 with leverage and terms adjusted. Credit floors begin at 620 in parts of the network, most programs want around 660, and 700 or higher opens the strongest leverage.
Reserves vary by lender, leverage, loan size, and transaction type. They commonly run around six months of PITIA, with loans above $1,500,000 typically stepping up to about nine months. Conservative rate-and-term files at modest leverage under that size can see reserves waived. Some property types are simply not offered: manufactured homes, log homes, and barndominiums. A replacement property in one of those groups will not work as new collateral.
Entity ownership matters too. Where properties sit in different LLCs, every owning entity has to sign, and personal guaranties stay in place after a property leaves the lien, subject to lender program eligibility. A larger down payment can lift coverage, but it does not erase leverage caps, credit floors, or property eligibility. The strongest files clear both tests: enough equity and enough rent.
What Can Go Wrong
- No clause at all. If the note has neither a release nor a substitution clause, you are negotiating. The realistic options narrow to a lender-consented release, a full payoff, or a refinance.
- A default or delinquency. In the illustrative agreement above, substitution is barred while a default exists. Lender practice on a delinquent or vacant property is likely similar, though it varies by note.
- A failed re-test. If the remaining pool does not hold up after a release, you may need to pay down more or add a stronger property.
- A weak replacement. A new property that is vacant, under-leased, or of lower value can sink a substitution request.
- Confusing it with defeasance. Northmarq’s explainer on defeasance describes a different concept: replacing real estate collateral with securities, mostly in securitized commercial loans. It is not what happens on a typical DSCR rental package.
- Tax surprises. Tax treatment varies; consult a qualified professional.
A fallback worth keeping in mind is separate loans per property. They avoid release and substitution terms entirely, at the cost of more loans to manage.
The Verdict
Pick substitution when the pool works and you want to change one piece with minimal disruption. Pick release and add when you want to sell, when your note only offers a release clause, or when the next purchase differs a lot from the property leaving. Choose the structure that matches your note, not your preference, because the contract decides what is available.
Before you commit, check four things: whether the note has either clause, whether the lender must consent, how the remaining pool tests after the change, and whether the incoming property has a lease and market rent that hold up. For the broader product picture, see the complete DSCR loans guide.

Frequently Asked Questions
Can I add a property to an existing DSCR loan after closing?
It depends on the note and the lender. Some lenders handle an addition as a modification, while others treat it as new financing. Either way, the new property is underwritten as a rental with its own lease and market rent, subject to lender guidelines.
Can a vacant property be the substitute?
Sometimes, but it is a harder case. The lender can rely on market rent alone, which usually means a more cautious read. A leased replacement with documented rent is a cleaner file, and an ineligible property type will not work at all.
Does a strong pool coverage ratio guarantee a release?
No. The lender usually re-tests the remaining properties at release time, and consent is a separate question from the numbers. A healthy ratio helps, but the release terms in the note still control.
Does the 1007 or 1025 form mean agency rules apply to my DSCR loan?
No. The forms are borrowed for rent and income documentation. Agency underwriting rules do not govern DSCR files, which qualify primarily on property-level rental income covering the payment, subject to lender guidelines.
Do release terms apply when each property sits in its own LLC?
Often the structure changes. Each owning entity typically has to sign, and guaranties continue after a property leaves the lien. Specifics depend on lender program eligibility and how the loan is papered.
