The Quick Read: Start by getting the duplex recorded in your name, your trust’s name, or your LLC’s name, because a lender can only take a lien from the person or entity that holds title. Once title is recorded and both units are leased (one vacancy at most), the line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Your personal income is not part of the test, and the tenants help the file instead of blocking it.
- Title comes first. An open estate with no recorded deed generally cannot pledge the property.
- Rent drives approval. Minimum coverage is 1.10x, tested on a stress payment over the whole line, through select programs.
- Leverage is capped. A second lien tops out at 70% combined loan-to-value at a 720 score or better, on lines of $50,000 to $500,000.
- Seasoning applies. A rental bought or refinanced in the last 6 months is not eligible, and title must be held for 6 months.
- Footprint is limited. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Inheriting a duplex with tenants already paying rent feels like a head start. In many ways it is. The rent is documented, the units are occupied, and nobody has to hunt for a renter. What slows heirs down is rarely the tenants. It is title, timing, and the first mortgage the decedent may have left behind.
This guide walks through the mechanics in order, from what the product is to the edge cases where the general rule breaks. For the broader picture of how rent-qualified lending works, Lendmire’s complete DSCR loans guide covers the foundation.
What Is a DSCR HELOC on a Rental?
A DSCR HELOC is a revolving line of credit secured by a non-owner-occupied rental. It is written as a standalone second lien behind a first mortgage you keep, or as a standalone first lien on a rental with no mortgage. The rent qualifies it. No traditional personal-income documentation, W-2s, pay stubs, or debt-to-income ratio are part of the file.
Two features matter for an heir. First, the line sits behind the existing first mortgage, so an inherited loan can stay in place instead of being refinanced away. Second, the property can be vested in an LLC, subject to lender program eligibility, with the members signing as guarantors.
It is not a closed-end second lien that pays out one fixed amount, and it is not a consumer HELOC on a home. It is never offered on an owner-occupied property or a second home. Because it is a business-purpose investor product, it is reviewed differently from a standard owner-occupied mortgage.
Key Terms Defined
DSCR (debt service coverage ratio): Gross monthly rent divided by the qualifying payment; the program here requires at least 1.10x.
Second lien: A loan recorded behind the first mortgage, paid after it if the property is ever sold or foreclosed.
CLTV (combined loan-to-value): The first mortgage balance plus the new line, divided by the property’s value.
Draw period: The 5-year window when you borrow against the line and pay interest only on the drawn balance.
Seasoning: The required time since the property was last bought or refinanced, and the time you have held title.
Letters testamentary: The court document that gives an executor authority to act for an estate.
Step 1: Get Title Into a Name That Can Pledge It
A will does not move title by itself. Until the property is deeded to the heir, a trust, or an entity, the owner of record is still the decedent. If probate is open and title has not transferred, the duplex generally cannot be pledged.
The stages look like this:
| Stage | Who can sign | Usually workable? |
|---|---|---|
| Probate open, no deed | Executor, with court authority | Generally not for this line |
| Executor’s deed recorded | New owner of record | Yes, once seasoning is met |
| Transferred to a trust | Trustee | Yes, subject to program terms |
| Held in an LLC | Person controlling the LLC | Yes, subject to program terms |
The title search comes next. Exceptions, a skipped probate step, or ancillary probate for out-of-state property all have to be cleared before a lender will insure the lien. Ask a probate attorney to confirm each step, because tenant-specific questions such as who collects rent during probate fall outside what a lender can answer.
If you inherited the duplex with siblings, every owner usually has to sign. One heir cannot pledge the whole property. A buyout of the other heirs is a separate transaction, and it needs a clean transfer of title first. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument, and the borrowers on the line need not be the borrowers on the first mortgage.
What Happens to the Mortgage the Decedent Left?
The existing first mortgage can often stay. Federal law limits a lender’s ability to call a loan due when a home passes to a relative at the borrower’s death, under the Garn-St Germain Act. That protects the old loan. It does not force any new lender to extend new credit.
This is where the second-lien structure earns its place. Instead of replacing the inherited first mortgage through a cash-out refinance, you add a line behind it. Leverage is measured on combined balances: the first mortgage plus the new line, divided by value. On a second lien, that tops out at 70% CLTV at a 720 credit score or better, with lines from $50,000 up to $500,000. Below 720 there is no second-lien tier. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
If the property has no mortgage at all, a first-lien line is possible. On lines up to $500,000, first-lien leverage reaches 75% LTV at 740 or better and 70% LTV from 700 to 739. Lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling at 720 or better. All of these are ceilings, subject to underwriting, and a declining-market flag lowers them by 5 points. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
One trap: a reverse mortgage on the property is a different situation. Those loans generally come due at the borrower’s death, so a line behind one is not a realistic plan.
How Do Tenants in Place Count Toward Qualifying?
Tenants in place count as documented rent, and a signed lease is required. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. So a below-market lease the decedent granted to a long-time tenant holds your ratio down, while a strong lease at or near market helps.
For a duplex, the appraiser uses the small residential income property form, Form 1025, which Fannie Mae’s Selling Guide lists as the form for two-to-four unit properties. The market rent comes from that report’s rent schedule. The 1007 rent schedule name you may see elsewhere refers to the single-family version.
A two-to-four-unit property may have at most one vacant unit. A duplex with one empty unit can still be reviewed, but the vacant side has no lease behind it, so the ratio will be tighter. Month-to-month tenants and expired leases are worth sorting out before you apply. Get fresh leases signed or documented where you can.
Leases with relatives of the decedent or heir get closer scrutiny. So does any informal arrangement with no payment history. Bank records showing rent deposits solve most of those questions.
If you plan to move into one unit, stop. That makes the property owner-occupied, and this non-owner-occupied line does not apply.
How Is the Coverage Ratio Calculated?
The test is gross monthly rent divided by a qualifying payment, and the line needs at least 1.10x. The qualifying payment is a fully amortizing principal-and-interest payment on the entire credit limit, calculated at the start rate plus 2 percentage points. That is a stress test. It assumes you have drawn everything, whether or not you do. Taxes and insurance are not part of that qualifying payment.
Run it conceptually. Say a duplex’s two units together rent for an amount that covers the stress payment on a $200,000 line with a little room to spare. That lands near 1.15x, which clears 1.10x. Size the line to $300,000 on the same rents and the ratio drops below the floor, because the payment is tested on the full limit. The practical lesson: the rent sets the ceiling on line size as much as equity does.
On a second lien, whether the first-mortgage payment joins the qualifying payment is not published. Confirm on the file how the lender treats it. The lender’s own coverage calculation governs, and any worked arithmetic is illustrative.
What Does the Valuation Look Like?
The equity side is measured on a fresh valuation, not on what the decedent paid or on tax basis. The IRS explains in Publication 551 that inherited property generally takes a basis equal to its fair market value at the date of death. That figure matters for a future sale and for depreciation. It does not raise how much you can borrow. Lenders size on current value.
Lines up to $400,000 use an automated valuation with a confidence score of 85 or better plus a property inspection report, or a full interior appraisal. Lines above $400,000 require a full interior appraisal. Appraisal waivers are not accepted. Smaller second liens get an owner-and-encumbrance report on title, while first liens and second liens above $400,000 carry a full title policy.
Tax treatment varies; consult a qualified professional.
How Do Draws, Terms, and Seasoning Work?
Lines start at $50,000. At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000, so on the smallest lines the whole line is drawn up front. Later draws are at least $5,000 each. This is not a line you open and leave mostly unused.
The draw period is 5 years, interest-only on the drawn balance. A 25-year fully amortizing repayment period follows, with a 30-year maturity. The rate is variable, and the lender’s HELOC disclosures carry the pricing terms.
Seasoning is where inherited property surprises people. 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). A transfer of the deed to a new entity can affect how those clocks are read, so ask before you move title around.
The credit side is plain. The minimum score depends on the lien: a second lien, which is the only option for an heir who keeps a first mortgage, needs 720 or better, while a first lien on a rental with no mortgage needs at least 700. On a first lien, the score also sets the leverage tier: 740 or better reaches 75% LTV, and 700 to 739 reaches 70% LTV. There can be no 30-day mortgage late in the last 12 months, and 48 months must have passed since a bankruptcy, foreclosure, short sale, or deed-in-lieu. No reserves or cash to close are required. A borrower can have at most 5 loans or $2,500,000 with the program. The borrower must be a U.S. citizen, permanent resident, or non-permanent resident with a Social Security number.
Where the Rule Breaks: Edge Cases
Most programs share the same broad shape, but these situations change the answer.
Probate still open. Possession is not title. Wait for the recorded deed.
Several heirs. One heir cannot sign for the rest. Either everyone joins, or one heir buys the others out and records the transfer first.
LLC owned the duplex. Title did not change at death, but control of the LLC did. Sort out who has authority before applying. Moving a mortgaged property into a new LLC mid-probate can also raise due-on-sale questions with the existing lender.
One unit vacant. One vacancy is the limit. Two units vacant in a fourplex-style file, or a fully vacant duplex, is outside the program.
Heir lives in one unit. The property is owner-occupied, so this non-owner-occupied lane does not apply.
Property type outside the program. Row homes, condotels, leaseholds, rural-designated property, mixed-use, and property listed for sale in the prior 2 months are not eligible. A Philadelphia property carries a ceiling 10 points lower.
Consumer-versus-business treatment. A line on a non-owner-occupied rental is generally treated as business-purpose credit under Regulation Z, which is why this is a different product from a home HELOC. Business credit can be rewritten as consumer credit in some cases, so the lender’s own classification governs.
HELOC, Cash-Out Refinance, Buyout, or Sell?
The decision depends on the first mortgage and your plans for the duplex.
| Path | Best when | Watch for |
|---|---|---|
| DSCR HELOC (second lien) | A low inherited first mortgage is worth keeping | 70% CLTV cap; most of the line drawn at closing |
| DSCR HELOC (first lien) | No mortgage on the duplex | 75% LTV needs 740 or better |
| Cash-out refinance | You want to replace the old loan | Gives up the inherited first mortgage |
| Buy out co-heirs | Siblings split ownership | Needs clean title first |
| Sell | Equity matters more than income | Gain depends on basis |
And if your income is the stronger side of the file, the investment property HELOC rules for an inherited rental with tenants in place cover the personal-income route.
Where the program works best: an heir with title recorded, a modest first mortgage worth keeping, both units leased near market, and a plan to put proceeds into repairs or the next rental. Where it works poorly: a half-vacant duplex, a tangled title, or an owner who wants to live in one unit.
Step-by-Step: From Deed to a Complete File
1. Confirm who holds title and record the deed, trust transfer, or entity documents.
2. Clear the title search and any probate exceptions.
3. Gather a lease for each occupied unit, plus rent receipts if a lease sits above market.
4. Collect the existing mortgage statement, insurance proof (covering both liens), ID, and credit report.
5. Pick the lien position: second behind the kept mortgage, or first on a rental with none.
6. Size the line against the 1.10x test on the full limit, not just the amount you want to draw.
7. Order the valuation the line size requires.

Frequently Asked Questions
Can I get a DSCR HELOC while the estate is still in probate?
Generally not. A lender needs recorded title in a borrower who can pledge the property, and a will alone does not transfer title. Once the deed, trust transfer, or entity ownership is recorded, the file can move forward, subject to the seasoning clocks.
Does a below-market lease hurt the application?
Yes, it can. A lease below market holds the coverage ratio down, so raising rent at renewal, where the law and lease allow, may help future files.
How much seasoning does an inherited duplex need?
Two six-month clocks apply: the line is not available on a rental bought or refinanced in the last 6 months (last note date to new note date), and title must have been held for 6 months (settlement date to note date). A deed transfer can affect how the clocks are read, so confirm before moving title.
Can I use the line if the duplex has a mortgage I inherited?
Yes, as a standalone second lien, at up to 70% CLTV with a 720 score or better. The first mortgage stays in place.
Does the step-up in basis increase how much I can borrow?
No. Basis is a tax figure. The loan is sized on the current valuation, the rent coverage, and the leverage tiers, all subject to lender guidelines.
