The Quick Read: It depends on three things: the home’s value times the lender’s combined ceiling, minus every loan already on the property, then trimmed by flat dollar caps and your personal qualification. A recent purchase usually leaves little room, because most buyers start with a large first mortgage. The ceiling also depends on how you use the home, and an investment property gets the lowest one.
- On Lendmire’s network, an investment-property line tops out at 70% combined loan-to-value (CLTV) and a $500,000 maximum line.
- A primary home or second home can reach 90% CLTV, but only at a 720-or-better credit profile.
- A buyer who put 20% down on a rental has no room under the investment ceiling, because a first mortgage of 80% of value already sits above the 70% cap.
- The line is underwritten on you (credit, income, debt load), not on the rent.
- A property held in an LLC cannot take this product. A DSCR cash-out refinance is the usual alternative.
A home equity line of credit (HELOC) sounds like instant access to cash once you own the place. In practice, a new owner’s equity is mostly the down payment plus a little appreciation. That is what the lender lends against.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
This guide shows the math, the exceptions, and where an investor should look elsewhere.
Key Terms Defined
HELOC: A revolving credit line secured by a property you own. You borrow, repay, and borrow again up to a limit.
CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the property’s value. Lenders cap this number.
Lien: A lender’s legal claim against a property. Your mortgage is a lien, and so is a HELOC.
Seasoning: The time you must own a property before a lender treats its appraised value as the basis for new borrowing.
DTI (debt-to-income): Your monthly debt payments divided by your monthly income.
Draw period: The stretch when you can pull money from the line. After it ends, you repay the balance.
The Formula in Three Steps
The limit is value times the ceiling, minus what you owe, capped by a flat dollar amount. That is the whole structure. Everything else here is a reason the number comes out smaller than expected.
1. Multiply the value by the CLTV ceiling. This gives the total debt the lender will allow against the property.
2. Subtract existing liens. Your first mortgage comes off the top. When you add a line, the full limit of that line counts against the ceiling, not just the portion you draw.
3. Apply the dollar caps. The result is the lesser of the equity room and the program’s maximum line. A minimum line size applies too, so very thin equity can fall short of the smallest line offered.
The CFPB’s HELOC booklet describes the same method. A lender takes a percentage of the home’s value and subtracts the mortgage balance. The percentage in that booklet is only a teaching example, and every lender sets its own.
The line is also a second mortgage if you already have a first one. The CFPB’s home equity explainer says you pay it on top of your first mortgage.
What Does the Network’s Ceiling Look Like by Occupancy?
The ceiling changes with how you use the property, so one number never fits. The figures below come from the select wholesale lenders Lendmire works with, and every one is subject to lender guidelines and full file review.
| Occupancy | Top CLTV | Credit needed | Max line |
|---|---|---|---|
| Investment property | 70% | 700+ | $500,000 |
| Second home | 90% | 720+ | $500,000 |
| Primary residence | 90% | 720+ | $500,000 at that tier |
| Primary residence (larger line) | 75% | 700+ (720 on the longer-runway program) | $750,000 at that tier |
Primary residences also have a larger tier: 75% CLTV at 700 or better, with lines up to $750,000. Lines above $500,000 are primary-residence only and require a full appraisal.
On an investment property, a 700 score and a 720 score reach the same 70% ceiling. A higher score adds eligibility, not leverage. Lines on all three occupancy types start at $25,000.
Lendmire arranges these lines through its wholesale partners and is not the lender. The lines are available only in the 16 states where Lendmire offers full-service mortgage lending. That footprint is narrower than its 41-market DSCR platform.
What Can a New Buyer Actually Borrow?
For most new buyers the answer is little or nothing in the first months. The size of your first mortgage decides it. Here is the room, as a share of the property’s value, at the two ceilings that matter most.
| Down payment at purchase | Room on an investment line (70% cap) | Room on a primary line (90% cap, 720+) |
|---|---|---|
| 5% | None | None |
| 10% | None | None |
| 20% | None | About 10% of value |
| 30% | None (already at the cap) | About 20% of value |
| 40% | About 10% of value | About 30% of value |
Read the table against what you paid, not what you hope the property is worth. It assumes the lender values the property at your purchase price and ignores flat dollar caps. Appreciation or renovation can change both.
The same arithmetic works for any first mortgage size. A first mortgage near 60% of value (a 40% down payment) leaves up to 10% of value under a 70% cap, and up to 30% under a 90% cap. A first mortgage of 70% or more leaves nothing under the 70% cap.
This is why a typical rental purchase, financed at 75% to 80% on the first mortgage, sits above the investment ceiling on day one. The first mortgage alone uses more than the lender will allow in total.
Lendmire’s piece How Much Can You Borrow on an Investment Property HELOC Right After Buying Your Home? covers that first-months picture in more detail.
Will the Lender Use Your Purchase Price or a New Appraisal?
That varies by lender, and it matters more than most buyers expect. Lines at or below $500,000 ordinarily run on an automated valuation, which is a computer estimate of value with no traditional appraisal. A higher CLTV may call for a second valuation. You can also ask for a full appraisal in any case.
The seasoning question is where lenders differ most. Lendmire’s wording is that seasoning applies if you bought recently, and the length depends on the lender. No single rule sets it.
Investor accounts show the same variety. One user on BiggerPockets describes a six-month wait before the bank would count appraised value, with purchase price used until then. A poster in another BiggerPockets thread says many banks use purchase price during the first year. The same thread says some lenders skip seasoning altogether and lend on purchase price plus renovation costs. Those are individual experiences, not a rule.
Plan on the lower of the two numbers. If the home appraises above what you paid, the same first mortgage becomes a smaller share of value, and room opens up. If the lender sticks to purchase price, only paying down principal creates room.
What Else Limits the Line Besides Equity?
Equity is the first test. Your personal profile is the second, and either one can cap the line. This product is underwritten on you, not on the property’s rent.
- Credit: The network’s minimum scores are 600 for primary residences, 640 for second homes, and 700 for investment properties. Reaching the top 90% CLTV tier on a primary or second home takes 720 or better. The lender reads a single-bureau score tied to the primary wage earner. The report can be no more than 90 days old at closing.
- DTI: The maximum is 50%, and 45% for profiles from 600 to 679. A ratio above 45% requires a score of 680 or better. The lender reviews your file on the interest-only payment calculated on the maximum draw.
- Draw at closing: At least 75% of the line is drawn at closing. That surprises people who expected an unused safety net.
- Exposure: A borrower can hold at most three lines. Owning more than 15 financed properties makes you ineligible.
- Property type: Single-family, 2-4 units, PUDs, townhomes, and condos (including non-warrantable ones) can qualify. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
- Listing status: In some states a property listed for sale, or listed within the past 60 days, is ineligible.
Pricing on these lines floats through both the draw and the repayment period. A bigger balance means a bigger payment, and the payment varies with it. The CFPB makes the same point about HELOCs generally.
Across the lenders Lendmire places files with, the combination matters more than any single number. A lender may be happy with your credit and still cap the line because the first mortgage is too large. The reverse happens too.
The LLC Problem
If your rental sits in an LLC, this product is not available to you as is. Title must be held by you personally or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. That is the sharpest structural difference from a DSCR loan.
A property already deeded to an LLC needs a vesting change, or a different loan. Moving title back to yourself can have its own consequences, so think it through before you deed anything. A deed change does not alter the amount you can borrow, because the limit is sized from CLTV. It does change who owns the property and who must sign.
An investor on BiggerPockets reports that finding a bank that would lend on an LLC-owned property was the hurdle.
Where a DSCR Cash-Out Refinance Fits Instead
Once the equity exists, many investors compare a HELOC with a DSCR cash-out refinance. A DSCR loan is an investor loan that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The cash-out version replaces your original mortgage instead of sitting behind it.
The two products behave differently.
| Factor | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| Reviewed on | Credit, DTI, equity | Rent versus payment |
| Original loan | Stays in place | Replaced |
| Top leverage | 70% CLTV | Around 75% LTV on standard rentals |
| Size | Up to $500,000 | Up to $3,000,000 on standard programs |
| LLC title | Not allowed | Allowed, subject to lender program eligibility |
| Seasoning | Varies by lender | About 6 months is common |
Coverage works like this. The lender divides monthly rent by the full monthly obligation: principal, interest, taxes, insurance, and any HOA dues. A ratio of 1.00 is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted.
Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside that calculation.
DSCR credit requirements run along the same lines. A 620 floor exists in parts of the network, most programs want around 660, and 700 or better opens the strongest leverage tiers. Reserves commonly run around 6 months of the full payment but vary by lender, leverage, and loan size.
The difference for a growing portfolio is personal debt load. A HELOC depends on your DTI, so each new property can crowd you out. A DSCR cash-out is sized on the property’s rent coverage instead. Lendmire’s complete DSCR loans guide walks through that qualification logic.
Using a HELOC to Buy the Next Property
Many investors borrow on a line first and refinance later. The sequence is simple: buy with the line as the down payment, season the property, refinance into long-term financing, repay the line, and repeat. One investor on BiggerPockets describes it as purchase, season for six months, refinance, pay off the HELOC, repeat.
The strategy has a hard limit. It only works if the refinance can actually pay the line off. At typical purchase leverage, a refinance caps near 75% LTV on a standard rental. The line has to fit under that combined ceiling too. Stack the line on a heavy first mortgage and the refinance may not cover both. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Two more cautions apply. Payments on the line float with the balance, so a plan that depends on a low payment can change underneath you. And if you use a line against your own home to fund the purchase, check the terms. The CFPB booklet warns that renting your home out to others may be prohibited under the terms of your line.
How Much Should You Actually Draw?
Draw what the project needs, not the maximum. A smaller draw keeps your DTI lower and your payment smaller. Remember that this network’s lines require at least 75% drawn at closing, so the decision happens before you sign, not after.
A short test helps. Ask whether you can repay the draw from sources other than the next loan. If the answer depends entirely on a future refinance, the plan is thin. Also keep in mind that if you sell the property, the line generally has to be paid off in full right away.
What Moves the Number in the First Year?
Three things can raise your room over time:
- Principal paydown. Each payment lowers the first mortgage balance, which shrinks the share of value it uses.
- Appreciation. A higher value, once the lender recognizes it, widens the room. A drop in value does the reverse.
- Improvements. Work on the property may support a higher appraised value, depending on comps and underwriter review. Never assume a specific lift.
Meanwhile, the profile side also moves. A newly opened line adds to your debt picture, and a fresh purchase adds a new payment. Applying before the purchase is final can sometimes make the file look cleaner, though each lender handles that differently.
Before You Apply
Gather these first:
- Your recorded deed and title name, which must match an eligible vesting form.
- A current mortgage statement showing the balance.
- Proof of income and your debt obligations.
- A realistic value estimate, so you know the CLTV before you apply.
- A clear decision on whether the property is a primary home, second home, or investment, since that sets the ceiling.
Run the formula yourself before applying. If the result is a small number, ask whether the cost and effort of a line are worth it, or whether waiting a few months changes the picture.
Frequently Asked Questions
Can I get a HELOC right after closing on a home?
Sometimes, but the amount is usually small. No single rule sets a waiting period. Some lenders apply seasoning, and others use the purchase price instead of an appraisal for a while. With a large first mortgage, your combined ceiling often leaves no room at all in the early months.
Can I borrow 100% of my equity?
No. The ceiling is set below full value, so the line is always less than your total equity. On Lendmire’s network, an investment property reaches 70% CLTV, and a primary or second home can reach 90% at a 720-or-better profile. Flat dollar caps can lower the result further.
Does a higher credit score raise my limit on a rental?
Not at the top. On an investment property, 700 and 720 profiles both reach 70% CLTV and the same $500,000 maximum. A better score can help you qualify, but it does not lift the ceiling. On a primary home or second home, credit tiers do change the ceiling.
Can I use a HELOC if my rental is in an LLC?
Not on this product. A DSCR cash-out refinance can work for LLC-held rentals, subject to lender program eligibility.
Is a HELOC sized on rent like a DSCR loan?
No. A HELOC is reviewed on your credit, your DTI, and the property’s equity. A DSCR loan is reviewed primarily on whether the property’s rent covers its payment, subject to lender guidelines.
