The Quick Read: It depends on equity and rent, not on the size of the renovation: on a rental where you keep the first mortgage, a DSCR HELOC reaches up to 70% combined loan-to-value at a 720 score, on lines from $50,000 to $500,000, and the rent must cover a stress payment on the whole line at 1.10x or better, subject to underwriting. A renovation loan is sized on the project instead.
- A second-lien line tops out at 70% CLTV (first mortgage plus the new line, divided by value) at a 720 score, through select programs.
- A first-lien line on a rental with no mortgage reaches 75% LTV at 740 or better, and 70% LTV from 700 to 739, on lines to $500,000. Larger first-lien lines run to $1,000,000 at a 65% LTV ceiling.
- The 1.10x coverage test runs on the entire credit limit, so a bigger line lowers coverage even before any money is spent.
- At least 80% of the line is drawn at closing, so size the line close to the actual budget.
- A vacant or gut-rehab unit does not fit, because a lease in place is required. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
How Is the Maximum Line Calculated?
The maximum line equals the property’s value times the combined-leverage ceiling, minus every lien already on the property. Your renovation budget never enters the formula. If the budget is larger than the room left, the budget loses.
A market guide from RentalRealEstate.com describes the same formula. The figure for this network is specific. On a second lien behind a mortgage you keep, the ceiling is 70% CLTV at a 720 credit score, on lines up to $500,000, subject to underwriting.
Here is a worked example in percentages only. Say the first mortgage balance sits at 45% of the property’s value. The ceiling is 70%. The room left is 25% of value, and the new line cannot exceed that. If the value converts that room to less than $50,000, there is no line to write, because $50,000 is the smallest line.
Now say the first mortgage sits at 66% of value. The room is 4% of value. On almost any rental, that is below the minimum line. A recent purchase financed at high leverage can land in the same spot, and a recent purchase also runs into the seasoning rule covered below.
The full credit limit counts toward combined leverage, not just the amount you draw. That matters when you pick the line size.
Key Terms Defined
DSCR (debt service coverage ratio): Gross monthly rent divided by the qualifying payment. The minimum on this program is 1.10x.
CLTV (combined loan-to-value): The first mortgage balance plus the new line, divided by the property’s value. It applies to second liens.
LTV (loan-to-value): The line divided by value when the line is the only lien. It applies to first liens.
Lien position: Where the line sits in line for repayment. A second lien sits behind the first mortgage. A first lien stands alone on a rental with no mortgage.
Draw period: The stretch when you can borrow against the line and pay interest only on the drawn balance. On this program it lasts 5 years, followed by a 25-year repayment period and a 30-year maturity.
Qualifying payment: The payment the lender tests rent against. It is not what you will actually pay each month.
What Does the Rent Test Do to the Line Size?
The rent test sets a second ceiling next to the equity ceiling. The rental must produce at least 1.10x its qualifying payment. That payment is a fully amortizing payment on the entire credit limit, calculated at a stress rate above the starting rate. Taxes and insurance are not part of it.
Two things follow. First, a larger line means a larger qualifying payment, so coverage falls as you add credit. Second, undrawn money still counts. A borrower who asks for a line far above the budget lowers coverage for no benefit.
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. A lease in place is required. On a two-to-four-unit property, at most one unit may be vacant.
The test reads the lease and the market rent as they stand on the file. Rent you expect after the work counts only once it exists in a lease and the valuation supports it. A renovation can lift rent over time, but the line is sized before that happens.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. The qualifying arithmetic here is illustrative, and the lender’s own calculation governs.
Second Lien or First Lien: Which Tier Applies?
Your existing debt decides the lien position. A rental with a mortgage you keep takes a second lien. A rental with no mortgage takes a first lien. The line is a standalone loan, so it is never closed together with a purchase, never a third lien, and never written on your own home or a second home.
| Factor | Second lien | First lien |
|---|---|---|
| Property status | Mortgage stays in place | No mortgage |
| Minimum score | 720 | 700 |
| Leverage ceiling | 70% CLTV at 720+ | 75% LTV at 740+; 70% LTV at 700-739 |
| Line size | $50,000 to $500,000 | To $500,000, then larger lines to $1,000,000 |
| Larger lines | Not available | 65% LTV at 720+ above $500,000 |
Write the figures with the right label. Second-lien numbers are CLTV because the first mortgage is counted. First-lien numbers are LTV. A first-lien line above $500,000 carries a 65% LTV ceiling, so more credit can mean less leverage per dollar. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
A declining-market flag on the property lowers the ceiling by 5 points. That can turn a borderline file into a smaller line.
Title can stay in the owner’s LLC, subject to program eligibility. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The people on the line do not have to be the people on the first mortgage.
How Does the Valuation Work?
An automated valuation with a property inspection report can set the value on lines up to $400,000. A full interior appraisal is the other route. Lines above $400,000 need a full interior appraisal. Appraisal waivers are not accepted.
Value drives the whole calculation, so a low number shrinks the line without changing the ceiling. The valuation sets the value on the file as it stands. Plan the line on current value and ask on the file whether any after-repair value counts before you count on it.
Hazard insurance must cover both liens, and flood coverage applies where it is required. Title work is lighter on small second liens and fuller on first liens and on larger second liens.
Why Draw Rules Change How You Size the Line
At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. On the smallest lines that means the whole line is drawn at closing. Later draws are at least $5,000 each.
This is the main difference from a renovation loan. A rehab product holds funds back and releases them as work finishes. This line puts most of the money in your account on day one, and interest-only payments start on the drawn balance. The FTC notes that you pay interest only on what you borrow, and that the rate on these lines is variable.
So the sizing rule is simple. Match the line to the real budget. A line far above the budget adds interest on money you do not need, adds to combined leverage, and lowers coverage.
The CFPB also notes that a lender may stop further draws if the property’s value falls significantly. Treat the later $5,000-minimum draws as available but not certain.
DSCR HELOC or Renovation Loan?
The line fits when the rental is leased, has equity, and needs work in phases or work that does not require the property to be empty. A renovation loan fits when the project is large, the unit is vacant, or the equity is too thin. A third option is replacing the first mortgage with a DSCR cash-out refinance. It is a separate file with a different structure.
| Factor | DSCR HELOC | Renovation loan | Cash-out refinance |
|---|---|---|---|
| Sized on | Equity and rent coverage | Project and after-repair value | Value and coverage on new loan |
| First mortgage | Stays in place | Usually replaced or paid off | Replaced |
| Funds released | Mostly at closing | Held back, paid in draws | Lump sum |
| Vacant unit | Not a fit | Often a fit | Needs lease evidence |
| Entity title | LLC allowed, per program | Varies by program | LLC allowed, per program |
An investment-property HELOC qualified on personal income is a different product with different rules. The same goes for a bank statement line, covered in Lendmire’s walkthrough of a bank statement HELOC for renovations. The DSCR version is the one where the rent qualifies the line and the owner’s personal income is never calculated, subject to lender guidelines.
The complete DSCR loans guide explains how the coverage test works across Lendmire’s investor programs.
Which Projects Fit: Light, Medium, Heavy
A light project is a cosmetic update on an occupied rental: paint, flooring, fixtures. The budget is small and the line minimum is $50,000, so the line may be larger than the job. Compare that against paying cash or a smaller product.
A medium project is a kitchen, a roof, or a systems upgrade on a leased unit. This is where the line fits best. The lease supports coverage, the equity may be enough, and the budget can land inside the $50,000 to $500,000 range. Check the combined leverage first, because a high first-mortgage balance can leave too little room.
A heavy project is a gut rehab or a unit that has to sit empty. The line does not fit. A rehab or bridge product is the usual tool, followed later by a long-term DSCR loan once the unit is leased.
What Takes a Rental Out of the Program?
Check these before spending time on numbers.
- Seasoning. 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).
- Credit. A second lien needs 720 and a first lien needs 700. Mortgage history must show no 30-day late in the last 12 months. A bankruptcy, foreclosure, short sale or deed-in-lieu must be at least 48 months back.
- Exposure. A borrower may carry at most 5 loans or $2,500,000 with the program.
- Property type. Rural-designated property, condotels, row homes, leaseholds, land trusts, age-restricted communities, mixed-use, modular and log homes are outside it. So are properties listed for sale in the prior 2 months and properties with a solar lien. Single-family, PUD, townhome, two-to-four-unit and condominium properties are eligible property types, and the leverage tiers above apply to each.
- Borrower type. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
- Footprint. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
No reserves and no cash to close are required, through select programs and subject to underwriting. The file still carries the lease, the credit report, the valuation and the title work.
Pairing the Line With a Later Refinance
Some investors use the line for the work, lease the unit at the improved rent, and later move the balance into a long-term DSCR loan. The line carries a variable rate, so the payment can change during the draw period, and it rises when the 25-year repayment period begins.
A renovation may support a higher appraised value, depending on comps and underwriter review. It does not set the line size.
Frequently Asked Questions
Can the line be sized to my renovation budget?
No. The ceiling comes from value, existing liens and rent coverage. If the budget exceeds the room, the line stops at the room. If the budget is far below the minimum line, you still borrow at least $50,000.
Does the full limit or only the drawn amount count toward combined leverage?
The full limit counts. Leverage adds the first mortgage balance and the new credit limit, then divides by value. The coverage test also runs on a payment calculated on the entire limit, so an oversized line hurts on both measures.
How long must I own the rental before I can take the line?
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).
Can an LLC hold title?
Yes, on investment property, subject to lender program eligibility. The members sign as guarantors, and a title holder who is not a borrower signs an acknowledgment and the security instrument.
What if the rental is vacant while I renovate?
A lease in place is required, and a two-to-four-unit property may have at most one vacant unit. A fully vacant rental or a gut rehab usually points to a rehab or bridge product, then a long-term DSCR loan after leasing.
