The Quick Read: One loan covers every property, and the lender runs two tests on the pool, then funds the lower result. The value test caps the loan at a share of cost or appraised value, depending on seasoning. The rent test caps it at what pooled rent can carry against the pooled monthly payment.
- Each rehabbed property gets its own appraisal and its own value basis. Fresh rehabs may size on cost, while seasoned ones size on appraised value.
- Your projected after-repair value is a planning number. The lender’s appraisal is the number that counts.
- On the 30-year portfolio loan, coverage is measured on the pool, so strong rentals can offset a weaker one.
- Release terms, cross-default exposure and bridge timing matter as much as the loan amount.
- A coverage ratio above the floor is not the same as positive cash flow.
You have finished several rehabs. Each one sits on its own short-term bridge note. Now you want one long-term loan to replace all of them. That is a different job from refinancing one house, and the sizing logic has more moving parts.
This guide walks through the sizing in the order a lender does it. It also covers the structures, where the rules bend, and how to decide whether a blanket makes sense. Program figures below reflect select lenders in Lendmire’s wholesale network, are typical ranges, and remain subject to lender guidelines.
Key Terms Defined
Blanket loan. One note secured by several properties. Every property backs the whole balance.
DSCR (debt service coverage ratio). Rent divided by the monthly housing payment. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
PITIA. Principal, interest, taxes, insurance and any HOA dues. It is the full monthly payment the rent has to cover.
Pooled coverage. Total rent from all properties divided by total PITIA for all properties.
Seasoning. The waiting period before a lender will size a cash-out loan on appraised value instead of what you paid.
Cost basis. Purchase price plus documented rehab spending.
ARV (after-repair value). Your estimate of what the property is worth after the rehab. It is a planning number, not a loan input.
Allocated loan amount. The slice of the blanket balance assigned to each property at closing.
Release price. What you pay to pull one property out of the pool. It usually runs above that property’s allocated balance.
Cross-default. A default on one property counts as a default on all of them.
What a Blanket Refinance Actually Is
A blanket loan is a collateral structure. DSCR is a qualification test. They show up together often, but they are separate design choices.
One note, several properties. Because every property secures the whole balance, a problem on one door touches the rest. Loan agreements commonly say so directly: standard cross-default language makes a default under any one mortgage a default under all of them. A plain-English explainer on cross-collateralization adds why a release clause matters, since it is the escape hatch when one property needs to leave the pool.
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.
Two structures show up in our network for this job:
- The 30-year portfolio loan covers 2 to 20 properties under one note. Loan sizes run from $300,000 to $5,000,000, with larger balances on review. Leverage goes up to 80% of value on a purchase or rate-and-term refinance. The coverage floor of 1.00 is measured on the pool. An interest-only period is available, and property types include single-family, 2-4 unit, condo and townhome.
- The rental portfolio term loan is for five or more rental properties or units. Loan sizes run from $500,000 to $50,000,000, with leverage 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 things like fraud and bankruptcy. Prepayment follows a yield-maintenance schedule. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Most rehab-exit files with a handful of doors fit the first structure. The rest of this guide uses it, because its pooled test is what makes mixed-stage rehabs workable.
How Underwriting Sizes the Loan, Step by Step
Think of sizing as a funnel with two caps. You build both caps, then take the smaller one. Here is the order.
Step 1: Set the value basis for each door
This is where rehabs change the picture. Cash-out limits sit on top of a seasoning rule. Inside the window, which most programs set at about six months, the lender generally sizes on cost basis. After the window, appraised value governs.
The clock typically starts when the deed records. It does not start when the rehab finishes. Investors trip on this constantly.
On the portfolio structures, leverage inside the first six months of ownership is typically limited to 90% of total cost. From six to twelve months it moves to 100% of cost. A rate-and-term refinance carries no cost restriction. A cash-out inside the first six months is capped by the seasoning rule. Strong coverage does not waive any of this.
Step 2: Apply the leverage cap
Cash-out never exceeds 75% of pooled value. A payoff-only refinance on the 30-year portfolio loan runs up to 80% of value. The rental portfolio term loan tops out at 75%. These are ceilings, not quotes. Credit, reserves and property review can all pull the actual number lower.
Step 3: Establish rent per door
Every property needs a lease or an appraiser-supported market rent. The lender orders its own appraisal for each door, and that appraisal produces both a value and a market-rent opinion.
For form names, the single-family rent schedule is Form 1007, and the small residential income property appraisal is Form 1025. Fannie Mae’s appraisal forms guidance explains when the rent schedule is used, and its list of forms gives the official titles. We cite them only to name the forms. DSCR files follow the network’s guidelines, not agency rules.
How the rent evidence plays out:
- A signed lease, deposit proof and first month’s rent make the cleanest door.
- A just-rehabbed vacant unit leans on the appraiser’s rent opinion alone.
- A month-to-month tenant is weaker, because underwriting may lean toward market rent.
- An above-market lease does not raise the ratio. A below-market legacy lease lowers it.
Step 4: Test pooled coverage
Add all the rent. Add all the PITIA. Divide. Stronger properties can offset weaker ones here. Underwriting tests the pool’s coverage, leverage and terms together, subject to lender guidelines.
Ask each lender one question early: does the test run on the pool only, or does it also test each door? Policies differ, and the answer changes which properties you can include.
Step 5: Take the lower cap
If the value-based loan amount is larger than rent can service, rent wins. A bigger payoff-plus-cash-out loan carries a bigger payment, which lowers the ratio. So rent can cap the loan before value does. That surprises people who expected the appraisals to be the limit.
Step 6: Net out the payoffs
The sized loan then pays off every bridge note, plus closing costs and any required reserves. Reserves commonly run about 6 months of PITIA, vary by lender, leverage and loan size, and step up to about 9 months on loans above $1,500,000. Whatever is left is your cash-out. If nothing is left, you did a payoff-only refinance. That is a legitimate outcome.
A Four-Door Pool, Worked Through
Run the numbers on a pool of four rehabs at different stages. These are modeled assumptions, not market data. Assume the four doors carry similar monthly payments, so pooled coverage equals the average of the four.
| Door | Stage | Value basis | Standalone coverage |
|---|---|---|---|
| A | Seasoned, leased | Appraised value | About 1.25x |
| B | Seasoned, leased | Appraised value | About 1.10x |
| C | Just finished, vacant | Cost basis | About 0.95x |
| D | Newly leased | Cost basis | About 1.30x |
| Pool | Mixed | Mixed | About 1.15x |
The pool clears 1.00 even though Door C sits below it alone. A rental below 1.00 can sit in a pool, but the pooled coverage, the leverage and the terms are what underwriting tests, subject to underwriting.
Doors A and B size on appraisal. Doors C and D size on cost. The value cap is built door by door, then added up. It is not one number applied to the whole group.
The proceeds waterfall then runs in this order:
1. Add the door-level value caps for the pooled leverage limit.
2. Build the rent cap from pooled coverage.
3. Take the lower of the two.
4. Subtract each bridge payoff and its costs.
5. Subtract closing costs and required reserves.
6. What remains is cash back, if any.
What happens when something goes wrong
| Variant | Effect on the pool |
|---|---|
| One door appraises low | Its value cap shrinks and proceeds drop, sometimes to a shortfall at closing |
| One door is not seasoned | It sizes on cost, which may be below what you hoped |
| Rehab overspent on one door | Appraisals may not recognize the extra dollars, so proceeds fall |
| One door removed from the pool | Remaining coverage and leverage are retested |
Overspending on one door does not automatically get offset by gains elsewhere. Each door’s cap is built on its own basis first. Gains on seasoned doors can lift the total, but the shortfall still shows up on the sizing page.
If an appraisal comes in low, you have three moves. Bring cash to close the gap, drop that door from the pool, or wait and refinance it later. A lender’s appraisal is not an opinion you can argue away with an ARV spreadsheet.
Where the General Rules Bend
Rules get fuzzy at the edges. These are the cases that cause surprises.
No release clause. A release clause exists only if it is written into the note. Blanket loans do not always include one. Without it, selling or refinancing a single property can mean paying off the whole loan. Terms vary lender by lender, so read the clause before you commit, not after.
Release price versus allocation. When a clause exists, the release price runs above the property’s allocated balance. After a release, the remaining properties may be retested for coverage and leverage. The remaining portfolio must still cover its debt service.
Payoff-only versus cash-out. A refinance that only retires the bridge loans and costs is treated differently from one that returns cash. Cash back triggers the cash-out limits. If you need the money to repay bridge notes and nothing more, a payoff-only structure can be a cleaner fit.
Seasoned versus unseasoned doors. The pool does not average away the seasoning rule. Doors still sit on their own clocks.
Property mix and size. Pools can mix single-family, condos, townhomes and 2-4 unit buildings. Larger pools step down on leverage and get reviewed case by case. Many programs also set minimums for property count and total loan size that a small portfolio may not meet.
Not eligible. Owner-occupied property, mobile homes, co-ops, mixed-use property and commercial property are ineligible in the pool. Manufactured homes, log homes and barndominiums are not offered in the network’s DSCR programs.
Entity requirements. A special-purpose entity, typically an LLC, is required on some structures, per lender program requirements. Each pledging entity needs its own papers at closing.
Credit. The floor on pooled structures is 640, and some portfolio structures want 680 or 720.
Bridge Timing Decides More Than You Think
The bridge notes have to outlive four things in sequence: seasoning, lease-up, appraisal and underwriting. If any bridge matures before the new loan closes, you may be negotiating an extension from a weak position.
Work backward from the earliest maturity. Then check extension terms and prepayment exposure on each bridge before you sign it. This is the planning step investors skip most often.
Staggered maturities add a wrinkle. If Door A’s bridge matures months before Door D’s, you either extend one note or refinance in stages. A split pool, with the seasoned doors in one loan and the fresh rehabs later, can solve it.
Blanket or Separate Loans?
One closing is the main draw. It is not automatically cheaper, though, and you give up per-door flexibility. The table compares your options.
| Option | Best when | Main cost |
|---|---|---|
| One pooled loan | Long hold, similar-stage doors | Cross-default and release terms |
| Separate payoff-only loans | Plans to sell some doors soon | More closings, per-door testing |
| Split pool | Some doors seasoned, others not | Two sets of closing work |
A pool fits long-hold investors best. The release clause rarely gets tested when nothing sells for years. If you flip a door every eighteen months, separate loans may serve you better.
One related thing to think about is how appraised value turns into cash. Lendmire’s piece How a Lender Sizes Your Cash-Out Refinance From Appraised Value covers that single-property logic.
What Across-the-Network Experience Shows
Across files like these, the most common stall is not the rent test. It is documentation. Investors finish the rehab but never assemble the paper trail, and the file sits.
Build one folder per door. The next table shows what it should hold.
| Stage | Documents |
|---|---|
| Rehab | Settlement statement, bridge note, deed, scope of work, invoices, permits, draw history, photos |
| Rent | Signed lease, deposit proof, first month’s rent, or appraiser’s rent opinion |
| Close | Insurance, payoff letter with a good-through date, entity papers |
Common Mistakes
- Treating your ARV as the loan input.
- Counting seasoning from rehab completion instead of deed recording.
- Signing a bridge note shorter than the seasoning wait.
- Assuming every blanket has a release clause.
- Reading a pooled coverage ratio as positive cash flow.
That last one deserves its own paragraph. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities and capex sit outside the calculation. Clearing 1.00 means rent covers the payment. It does not mean money lands in your pocket.
Also, a bigger down payment can lift coverage by shrinking the payment. It does not erase leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Frequently Asked Questions
Can I refinance right after the rehab?
Usually yes, but the sizing basis changes. Inside the seasoning window, which most programs set at about six months from deed recording, the loan generally sizes on cost basis. A payoff-only refinance carries no cost restriction on the portfolio structures. A cash-out inside the window is capped by the seasoning rule.
Does one weak property sink the pool?
Not on its own. On the 30-year portfolio loan, coverage is measured on the pool, so stronger doors can offset a weaker one. Underwriting still tests the pool’s coverage, leverage and terms, subject to lender guidelines. Ask whether a lender also tests each door separately.
Is the appraisal ever skipped?
No. DSCR means no personal income documentation, and qualification runs on the property’s income. The property is still valued and its rent still documented. Each door gets its own appraisal ordered by the lender.
Can I sell one property after closing?
Only as the loan documents allow. Partial releases, substitutions and single-property sales follow 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.
What if one rehab is not leased yet?
It relies on the appraiser’s market-rent opinion. A signed lease and deposit make a cleaner file, but a vacant door can still sit in the pool, with pooled coverage tested as a whole.
