The Quick Read: It depends on three numbers: the rental’s value, the combined leverage cap, and what you already owe on it. Through select programs in Lendmire’s network, a standalone second lien typically reaches 70% combined loan-to-value (CLTV) at a 720 credit score or better, on lines of $50,000 to $500,000. A first lien on a rental with no mortgage can reach 75% loan-to-value (LTV) at 740 or better. All of it is subject to underwriting.
- Max line = (value × the CLTV cap) − every lien already on the property.
- The rent qualifies the line at a minimum 1.10x coverage, tested on a stress payment over the whole line.
- Lines to $400,000 can use an automated valuation with a property inspection report, or a full interior appraisal; larger lines take a full interior appraisal.
- The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
You are fixing up a rental, not a home you live in. That changes which products exist and how big the check can be. Lendmire is a broker: it arranges these lines through a wholesale lender, and the lender approves the file.
How Is the Maximum Calculated?
The maximum is the property’s value times the combined leverage cap, minus every lien already on it. Federal consumer guidance describes the same logic: lenders set a HELOC limit as a percentage of the home’s value, then subtract what is owed, per the federal consumer-finance regulator’s HELOC booklet.
Here is the walk-through as a percentage example. Say a rental is valued at $500,000, you keep a first mortgage, and the borrower scores 720 or better. The 70% CLTV cap means the first mortgage balance plus the new line cannot pass 70% of value. Whatever room is left under that ceiling is your maximum, before the program’s own line-size limits.
Three things shrink that number:
- A big first mortgage. Every dollar of first-lien balance comes out of the same 70%.
- A lower credit tier. Below 720 there is no second-lien option in this program.
- A declining-market flag. It lowers the ceiling 5 points. Philadelphia lines carry a ceiling 10 points lower.
Lenders also keep a cushion. The federal consumer-finance regulator’s consumer guide on using home equity says lenders typically require 10% to 20% of home value to stay as equity. That is a general consumer figure, not a rental rule. The network’s cap is the number that governs here.
What Is a DSCR HELOC, and How Does It Differ From a Home Equity Loan?
A DSCR HELOC is a revolving line of credit on a rental you keep, qualified on the property’s rent instead of your personal income. DSCR means debt service coverage ratio: the rent divided by the payment it has to cover. A home equity loan is a lump sum. A line gives you a draw period first.
Here is how this program is built:
- Lien position. It is a standalone second lien behind a first mortgage you keep, or a standalone first lien on a rental with no mortgage. It is never a third lien and never closes with a purchase.
- Draws. At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. On the smallest lines, $50,000 is the whole line, so all of it is drawn at closing. Later draws are at least $5,000 each.
- Terms. A 5-year interest-only draw period, then a 25-year repayment period, on a 30-year maturity. The rate is variable.
- Not for your own home. It is never offered on an owner-occupied home or a second home.
That closing draw matters for renovations. If your repair budget is well under $50,000, this is the wrong tool, because the closing draw is never smaller than that. If the work comes in stages, the later $5,000 draws help, but most of the money still lands at closing.
How Does the Rent Test Limit What You Can Borrow?
The rent test caps the line as much as the equity does. The minimum is 1.10x: gross monthly rent divided by a qualifying payment. That payment is a fully amortizing principal-and-interest payment on the entire credit limit, at the start rate plus 2 percentage points. Taxes and insurance are not part of it.
So a bigger line means a bigger qualifying payment, and the coverage number falls. Think of it as a second ceiling beside the equity ceiling. A rental with plenty of equity can still hit the rent ceiling first.
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, and a two-to-four-unit property may have at most 1 vacant unit.
One point is not published, so check it on your file. On a second lien, the lender’s own coverage calculation governs, and the file should show how the lender treats the first-mortgage payment in that calculation. Ask for that before you size the line around the rent.
Can You Borrow Against Value After the Renovation?
No. Plan on the value as it stands today. 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. Appraisal waivers are not accepted.
That has a practical edge. A unit that is gutted or vacant works against a rent-based test, since a lease in place is required. A heavy rehab belongs in a different product, such as a short-term rehab loan. This line is built for a stabilized rental where you want to upgrade kitchens, roofs, or units while tenants pay.
Finished work may support a higher appraised value later, depending on comps and underwriter review. That helps a future refinance, not this line.
Why Might You Have No Room to Borrow?
Several program rules can leave you with nothing to draw, even with real equity on paper.
- A recent purchase or refinance. 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). Recently bought rentals often have little equity anyway, since the purchase price sets the starting value.
- A first mortgage that is already large. At the 70% second-lien combined cap, a first mortgage at or near 70% of value leaves little or no room to draw, and a first mortgage above that level, as can happen on a rental bought with 20% down, leaves none.
- Credit under 720 with a first mortgage in place. Second liens start at 720. Mortgage history also matters: no 30-day late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
- Property type. Rural-designated property, row homes, condotels, leaseholds, land trusts, mixed-use, modular and log homes, a property listed for sale in the prior 2 months, and a property with a solar lien are all outside the program.
- Exposure limits. A borrower is capped at 5 loans or $2,500,000 with the program.
Property types not on that exclusion list can qualify. They include single-family homes, PUDs, townhomes, two-to-four-unit properties, warrantable and non-warrantable condominiums, and lots to 10 acres.
How Do the Numbers Change With a First Lien?
A first lien exists only on a rental with no mortgage, and it can lend more. At 740 or better, LTV tops out at 75% on lines to $500,000. From 700 to 739, it is 70%. Lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling at 720 or better. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
| Factor | Second lien | First lien |
|---|---|---|
| Existing mortgage | Yes, you keep it | None on the rental |
| Leverage cap | 70% CLTV | 75% LTV (740+), 70% (700-739) |
| Credit floor | 720 | 700 |
| Line range | $50,000 to $500,000 | $50,000 to $1,000,000 |
| Large lines | Not available above $500,000 | 65% LTV above $500,000 |
The 700 floor in the first-lien column applies only to a rental with no mortgage. A borrower at 700-719 who still has a mortgage on the rental can only take a second lien, and the program offers a second lien only at 720.
Which Product Fits Your Project?
Pick by how the work will be paid out. A lump sum suits a fixed budget, while a line suits phased work. The NerdWallet guide to HELOCs on investment property also notes that these products are not offered by all lenders and carry stricter requirements than owner-occupied versions.
| Option | Reviewed on | Keeps your first mortgage? | Best for |
|---|---|---|---|
| DSCR HELOC (second or first lien) | Rent, 1.10x minimum | Yes, on a second lien | Staged work on a rental you keep |
| Investment HELOC on personal income | Credit, debt-to-income, documented income | Yes | Borrowers with strong personal income files |
| DSCR cash-out refinance | Rent, under that program’s rules | No, it replaces it | A large equity pull when the first mortgage terms are no bargain |
| Short-term rehab loan | The project itself | Varies | Gut rehabs and vacant units |
Compare a second lien against a full cash-out refinance on a blended basis: the first mortgage you keep plus the new line, versus one new first loan. A cash-out replaces the first mortgage and its terms. A second lien leaves them alone. Ask the lender for the pricing terms in its HELOC disclosures, then run both.
What Does It Cost to Carry While the Work Is Underway?
Interest is real even though the rent test ignores your personal budget. During the 5-year interest-only draw period, you pay on what you have drawn. Then the 25-year repayment period amortizes the balance.
Before you commit, test the renovation, not just the loan. Ask what the work does to rent, what it does to value, and whether the line’s payment still leaves the property cash-flowing. A falling coverage ratio on a bigger line is a warning sign.
Value risk exists too. A lender can freeze or reduce a HELOC if value falls significantly. Falling behind on the line can also put the property at risk. Keep a repayment plan that does not depend on the next draw.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
What Documents and Terms Should You Gather?
Bring these before you apply:
- The current lease and rent receipts, especially if rent runs above market.
- Title and vesting evidence. An LLC can stay on title; members sign as guarantors, subject to lender program eligibility.
- The first-mortgage statement, if you are keeping one.
- Proof of borrower status: US citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
- Hazard insurance covering both liens, plus flood coverage where required.
The file does not need tax returns, W-2s, pay stubs or a debt-to-income ratio. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. No reserves or cash to close are required under the program. For the wider framework, see Lendmire’s complete DSCR loans guide.

Frequently Asked Questions
What is the most I can borrow on a rental for improvements?
Lines run from $50,000 up to $500,000 on a second lien, and up to $1,000,000 on a first lien. Your actual cap is the lesser of the leverage math, the rent test and the line limits, subject to underwriting, unless three months of rent receipts support a lease above market. A second lien tops out at 70% CLTV; a first lien at 75% LTV. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
How long must I own the rental first?
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 the property?
Yes, an LLC can be vested on the investment property, subject to lender program eligibility. Its members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment.
Can I use the line on my own house or a second home?
No. This line is only for non-owner-occupied one-to-four-unit rentals. A primary-residence HELOC is a different, owner-occupied product.
Do I need an appraisal?
Yes, some form of valuation. Lines to $400,000 can use an automated valuation (confidence score 85 or better) with a property inspection report, or a full interior appraisal. Larger lines need a full interior appraisal. Appraisal waivers are not accepted.
