The Quick Read: Rarely, and not while the unit is gutted, because the program needs a leased rental that earns rent, and a gutted unit has no lease, no supportable market rent and an unsettled value and insurance picture, so the workable path is to settle the claim, repair, re-lease, and then apply, subject to underwriting. This line is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Here is what to take away:
- The rent has to be real. The program requires a lease in place, and a two-to-four-unit property may have at most 1 vacant unit.
- The value has to be supportable. Every file gets an automated valuation with an inspection report or a full interior appraisal, and appraisal waivers are not accepted.
- Flood coverage can be a condition. Where it is required, the policy has to be in place before the line is.
- Repairs come first, and other money pays for them. The line is not meant to fund the rebuild, so the repair costs have to be covered from sources outside it.
- After repair and re-leasing, the file looks like any other rental. The line is then reviewed on rent, credit and combined leverage.
Key Terms Defined
You will see these terms throughout. Each one is defined here once.
DSCR (debt-service coverage ratio): The rental’s gross monthly rent divided by the qualifying payment on the loan.
HELOC (home equity line of credit): A revolving line of credit secured by a property you own, so you draw against equity instead of taking one lump sum.
Second lien: A loan that sits behind the first mortgage you keep, so the first lender gets paid first if the property is sold.
First lien: A loan in first position, available on this program only on a rental with no mortgage.
CLTV (combined loan-to-value): Your first mortgage balance plus the new line, divided by the property’s value.
Special flood hazard area: A mapped high-risk flood zone, usually labeled A or V on a flood map, where flood insurance is required for certain mortgages.
Substantial damage: Damage where the cost to repair equals or exceeds 50 percent of the building’s value before the flood. It triggers local rebuilding rules.
Seasoning: The waiting period a lender wants after you buy or refinance a property before a new loan is allowed.
Why Does a Gutted Rental Fail the Test?
A gutted rental fails because the line is built on three things: rent, value and equity. A flood-gutted unit has none of the first two until it is repaired.
Start with rent. Across the wholesale network where Lendmire places these files, the rent qualifies the line. Rental income is reviewed in place of personal-income documentation, and no personal income calculation is made, subject to lender guidelines. The minimum coverage is 1.10x. That means gross monthly rent divided by a qualifying payment, which is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It is a stress payment, not the payment you will actually make.
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. Both halves of that sentence break down on a gutted unit. There is no lease in place, and an appraiser cannot assign a market rent to a unit with no kitchen, drywall or flooring.
A multifamily building adds one more wrinkle. A two-to-four-unit property may have at most 1 vacant unit. A fourplex where two units are gutted does not fit, even if the other two are fully leased.
Then there is value. Lines to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Either way, the valuation looks at the building as it stands. A gutted building does not carry the value it had before the flood, and the line is sized off value, so a lower value shrinks the line.
Is there a way around this by borrowing against a different property? Sometimes. The program writes a line against one rental at a time, though, so the damaged unit cannot simply be skipped if it is the collateral.
One more point on the coverage math. On a second lien, the lender’s own coverage calculation governs, so confirm on the file how the lender treats the first-mortgage payment. That detail changes the ratio on a rental that still carries a mortgage.
Does Flood Insurance Change the Answer?
Yes, because flood coverage can be a condition of the line, and the claim behind it decides how much you have to rebuild with. Standard landlord policies generally exclude flood, so a separate flood policy is usually the source of payment.
On this program, hazard insurance covers both liens, and flood coverage is required where the file calls for it. The lender’s own guidelines set that condition, so confirm it before you plan around the line. Where the property sits in a mapped high-risk zone, expect it.
A Library of Congress research report from the Congressional Research Service explains that the mandatory purchase requirement is enforced by the lender, not by FEMA. It also says an owner can meet the requirement with National Flood Insurance Program (NFIP) coverage or with a private policy that is at least as broad. The same report puts the NFIP building limit for a single-family residential unit at $250,000. Limits for buildings with two to four units differ, so check the policy itself.
Why does that limit matter here? If the rebuild costs more than the policy pays, you carry the gap. That gap is exactly what a line of credit could tempt you to fill, and it is the wrong use of a rent-qualified line on an unrepaired property. A private or excess policy can narrow the gap before repairs begin.
Insurance also hits your cash flow in a way the DSCR test does not. For this program, the qualifying payment is principal and interest on the full line at the stress rate. Taxes and insurance are not part of it. A higher flood premium will not lower the 1.10x coverage number. It will still reduce what you keep each month.
Rent loss is the other gap. An insurer’s explainer on flood and landlord coverage notes that NFIP does not pay for lost rental income. The months a unit sits empty during rebuilding are yours to absorb. Clearing a coverage ratio later does not make up for them.
What Is the 50 Percent Rule, and Why Does a Lender Care?
The 50 percent rule decides whether you can simply repair or must rebuild to current flood standards. A lender cares because that choice changes the scope, the cost, and the finished value of the collateral.
FEMA’s floodplain training unit on substantial improvement and substantial damage defines substantial damage as damage whose repair cost equals or exceeds 50 percent of the structure’s market value before the damage. It applies to buildings in a flood hazard area whether or not they carried flood insurance. If the threshold is crossed, the building must be brought into compliance. That usually means elevation, floodproofing, relocation or demolition. Your local community makes the determination.
Two details trip up investors. First, this is a floodplain-compliance decision, not an insurance payout decision. Crossing 50 percent does not mean your insurer owes you policy limits. Second, the rule is tied to the high-risk zone. Claims Journal reports that it applies only within a special flood hazard area, and that the Increased Cost of Compliance coverage on an NFIP policy, up to $30,000, is only accessible if the damage exceeds the 50 percent threshold. The same article calls it one of the most misinterpreted floodplain regulations. Some communities adopt stricter or cumulative thresholds, so ask your local floodplain office how it measures.
A written substantial-damage determination is a document a lender would reasonably ask to see. If your repair estimate crosses 50 percent, treat that as a different project. Your contractor scope, your timeline and your final value all change.
What Does the Lender Want to See?
The lender wants two files, and you build them in order. The first is the loss file, which proves what happened and how you are fixing it. The second is the finance file, which proves a leased, valued, insured rental exists.
Stage one, the loss file (now):
- The flood determination and the flood policy declarations page, showing the named insured and limits.
- Claim status and the adjuster’s scope of loss.
- Contractor bids, photos, and any permits.
- Any substantial-damage letter from the local community.
Stage two, the finance file (after repair):
- A signed lease on every occupied unit, with rent receipts if you want a lease above market to count.
- A valuation: automated with an inspection report on lines to $400,000, or a full interior appraisal on larger lines.
- Hazard insurance covering both liens, plus flood coverage where required.
- Entity and title documents if the rental sits in an LLC.
- A credit report from the lender’s own pull.
The loss file is not a program requirement. It is what makes the finance file easy to build later. These items are typical expectations on a file like this, and every file is underwritten individually.
What Do the Program Terms Look Like After Repair?
Once the rental is repaired and leased, the line works as a standalone second lien behind the first mortgage you keep, or as a standalone first lien on a rental with no mortgage. It is never closed together with a purchase.
Second lien, on an investment rental you already have a mortgage on: combined loan-to-value up to 70% at a 720 credit score or better, on lines from $50,000 up to $500,000. Below 720 there is no second-lien tier. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
First lien, on an investment rental with no mortgage: loan-to-value up to 75% at 740 or better on lines up to $500,000, and up to 70% from 700 to 739. Lines above $500,000, up to $1,000,000, carry a 65% ceiling at 720 or better.
A borrower who keeps a first mortgage can only take a second lien. A first lien exists only on a rental with no mortgage. Those are ceilings and floors, not offers, and they depend on underwriting.
The mechanics are the same on both. At least 80% of the line is drawn at closing, and later draws are at least $5,000 each. You get a 5-year interest-only draw period on the drawn balance, then a 25-year fully amortizing repayment period, with a 30-year maturity. The rate is variable. The rate and the pricing terms come with the lender’s HELOC disclosures.
On credit, a mortgage history with no 30-day late in the last 12 months applies. It takes 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required, and exposure is capped at 5 loans or $2,500,000 per borrower with the program.
Seasoning matters if you recently bought or refinanced the damaged rental. A rental bought or refinanced inside the last 6 months is not eligible (that clock runs from the last note date to the new note date), and the owner must have held title for 6 months (settlement date to note date).
The program also excludes certain property types. Rural-designated property, condotels, row homes and leaseholds are outside it. If an LLC holds the rental, the line can be vested in the entity for investment property, with the members signing as guarantors, subject to program terms. Lendmire’s complete DSCR loans guide explains the wider family of rent-qualified financing.
A Worked Example (Ratios and Percentages Only)
Run the numbers on a duplex with both units flooded, one gutted and one lightly damaged. The owner holds a first mortgage worth about 40% of the pre-flood value and has a 740 credit score. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
While damaged: The gutted unit has no lease, and the other unit may be vacant for cleanup. The property has more than 1 vacant unit. The coverage test has no rent to count, and the valuation reflects the damaged condition. The line is not a fit.
After repair: Both units are re-leased, and the appraisal’s market rent roughly matches the leases. Suppose rent clears the 1.10x test at the stress payment with some room, around 1.25x. A second lien could then be sized at 30% of value on top of the 40% first mortgage, which is the 70% CLTV ceiling at 720 or better. That is a ceiling, not an offer, and the lender’s own calculation governs.
Now add the flood premium. It does not change the 1.25x coverage number, because insurance sits outside the qualifying payment. It still reduces your monthly margin. A repaired rental that clears the ratio can still be thin on cash flow, so check that margin before you draw.
HELOC, Cash-Out Refinance, Rehab Loan or Insurance Money?
The right tool depends on what stage the property is in. Match each one to the stage, and the order of operations gets clearer.
| Option | When it fits | Main limit |
|---|---|---|
| Insurance proceeds | Gutted, claim settled | Capped by policy limits |
| Short-term rehab loan | Gutted, repairs underway | Needs a repayment exit |
| DSCR HELOC | Repaired, leased, equity | Needs lease, valuation, rent test |
| DSCR cash-out refinance | Repaired, replacing first mortgage | Replaces the existing first mortgage |
A cash-out refinance replaces the whole first mortgage, while the line sits behind it. That matters if the first mortgage is one you want to keep. A short-term rehab loan is financing built for properties under repair, and a common sequence is to rehab, re-lease, and then move to long-term financing. The line works at the end of that sequence, not the beginning.
The Path From Gutted to Financeable
Take the steps in this order. Each one sets up the next.
1. Document the loss with photos, the claim file, and the adjuster’s scope. 2. Settle the flood claim and see how far the policy limits go. 3. Get contractor bids and ask your local floodplain office whether the damage crosses the 50 percent line. 4. Fund repairs with insurance money, cash, or a short-term rehab loan. 5. Re-lease every unit, keeping at most 1 vacant unit in a two-to-four-unit building. 6. Confirm flood and hazard coverage are bound and match the lender’s condition. 7. Apply for the line, or compare it against a cash-out refinance.
Edge Cases Worth Knowing
Damaged but livable. If the flood damage was moderate and the unit stays leased, the line may still work. The lender’s condition standards decide that, so ask before you assume.
Outside a mapped flood zone. The 50 percent rule and the standard mandatory-purchase rule are tied to high-risk zones. A lender can still make flood coverage a condition of the file, so do not assume that being outside a zone means no requirement.
A rental you plan to sell. A property listed for sale in the prior 2 months is not eligible. That includes a damaged rental you tried to sell as-is.
Short-term rental use. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.

Frequently Asked Questions
Can I get a DSCR HELOC while my flooded rental is still being repaired?
Usually not. The program requires a lease in place, reviews the file on rent, and values the property as it stands. A unit under repair has no rent and an impaired value. The common route is to finish repairs and re-lease first, then apply, subject to lender guidelines.
Does a flood insurance claim in progress block the line?
It can complicate the file, since the value, the repair scope and the coverage all depend on how the claim resolves. Settle it first when you can. A bound flood policy matters where flood coverage is required, and the lender’s guidelines set that condition.
Will a higher flood premium lower my coverage ratio?
Not on this program. The qualifying payment is principal and interest on the full line at the stress rate, and insurance is not part of it. The premium still reduces your cash flow, so run your own margin before you draw.
What if I own the rental through an LLC?
Yes – the line can vest in the owner’s LLC (investment property only), with the members signing as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
Is a DSCR HELOC the same as a DSCR cash-out refinance?
No. The line is a standalone second lien behind the first mortgage you keep, or a first lien on a rental with no mortgage. A cash-out refinance replaces the first mortgage with a new loan. The right choice depends on whether you want to keep your current first mortgage.
