How a HELOC and a Cash-Out Refinance Cap Your Borrowing Limit

The Quick Read: Both products turn your property’s appraised value into a ceiling, then subtract what you already owe. A HELOC is measured by combined loan-to-value across every lien, while a cash-out refinance is measured against the new first loan, which replaces the old one and must fit under its own ceiling.

• On an investment-property HELOC, the network ceiling is 70% CLTV, with a line of up to $500,000 and a 700 minimum credit score.
• On a cash-out refinance of a standard rental, the ceiling is typically around 75% LTV. Short-term-rental collateral typically tops out at 70%.
• A DSCR cash-out refinance can reach loan sizes up to $3,000,000, with about 6 months of seasoning as the common expectation.
• On a DSCR cash-out, the rent has to support the new payment too, so the rent test can bind before the value test does.
• Every figure here is subject to lender guidelines and a full file review. None of it is a commitment to lend.

Key Terms Defined

You will see these terms all the way through, so here they are in plain words.

• LTV (loan-to-value) is one loan balance divided by the property’s appraised value.
• CLTV (combined loan-to-value) is every loan secured by the property, added together, divided by appraised value. Wall Street Prep notes that CLTV is nearly the same math as LTV. The only difference is how many loans go in the numerator.
• Lien position is the order in which lenders get repaid if the property is sold or foreclosed. A first mortgage is in first position. A line placed behind it is in second position.
• Draw period is the stretch when you can borrow from a line. A repayment period follows, when you pay the balance down.
• Seasoning is the waiting period a lender wants between buying a property and refinancing it.
• DSCR compares a property’s rent to its full monthly obligation: principal, interest, taxes, insurance, and any association dues. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.

The One Formula Behind Both Caps

Every cap works the same way. Multiply appraised value by the ceiling, then subtract everything the property already owes. What is left is the most you could take out, before costs.

Appraised value is the starting point for both products. A purchase price only matters until the property is seasoned. The appraiser’s number then takes over.

The two products differ in what gets subtracted. A HELOC leaves your first mortgage in place and sits beside it. So the first mortgage balance comes out of the room, and the new line must fit in what remains. A cash-out refinance replaces the first mortgage. The new loan pays off the old one, and you keep the difference.

Here is a percent-of-value picture. Say your first mortgage is 60% of the property’s value.

• An investment-property HELOC at 70% CLTV leaves 10 percent of the property’s value to borrow against.
• A cash-out refinance on a standard rental at 75% LTV leaves 15 percent of the property’s value, before closing costs and prepaids.
• A cash-out on short-term-rental collateral at 70% LTV leaves 10 percent of the value, also before costs. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

The calculator on this page can turn those percentages into dollars. The percentages are the part that does not change from property to property.

How a HELOC Caps You

A HELOC is capped by CLTV, and the cap shrinks as your existing debt grows. The federal consumer-finance regulator defines available equity as the home’s value minus the mortgage balance. Lenders then take a percentage of that equity.

The percentage depends on how you use the property. Across the equity-line programs in Lendmire’s wholesale network, the ceilings are tiered by occupancy:

• Investment property: 70% CLTV, a line of up to $500,000, and a 700 minimum credit score.
• Second home: up to 90% CLTV, but only at a 720-or-better credit profile. Lower scores step the ceiling down.
• Primary residence: up to 90% CLTV, also only at 720 or better. Larger lines follow a separate rule: any line above $500,000 is available only on a primary residence and needs a 700 or better credit profile (720 on the longer-runway structure). Those larger lines cap at 75% CLTV, so the 90% tier does not apply to them.

Market surveys differ. Yahoo Finance reports that many lenders accept CLTV up to 80% or 85% on home equity borrowing. That describes the broader market, mostly owner-occupied homes. On an investment property in this network, the ceiling is 70% CLTV.

Three other caps sit on top of the percentage:

• A dollar cap. On a high-value property, the $500,000 investment-line limit can bind before the 70% ceiling does.
• A personal debt test. The maximum debt-to-income ratio is 50%, and it is calculated on the interest-only payment at the maximum draw. Ratios above 45% need at least a 680 score.
• A line-count and portfolio limit. A borrower is limited to three lines, and owning more than 15 financed properties makes a borrower ineligible.

The HELOC is a personal-credit product. It looks at you, your credit, and your equity. The rent on the property barely enters the picture.

The investment line runs a 5-year interest-only draw period and then a 25-year repayment period. At least 75% of the line is drawn at closing. The line’s pricing floats and never converts to fixed. The line cannot be held by an LLC. It needs an individual borrower or a revocable living trust. Availability is limited to Lendmire’s 16 full-service states, which is narrower than its DSCR footprint.

How a Cash-Out Refinance Caps You

A cash-out refinance is capped by LTV on one loan. The new first mortgage cannot exceed the ceiling, and the payoff of the old loan comes out of that amount first. Across most of the network, a DSCR cash-out on a standard rental tops out around 75% LTV. Short-term-rental collateral typically tops out at 70% LTV on a cash-out.

Loan sizes reach up to $3,000,000 on standard programs, with smaller balances available through select lenders. Above $2,500,000, the network generally holds to 30-year fixed structures. Most programs want a credit score around 660. A 620 floor exists in parts of the network, and 700 or better opens the strongest leverage tiers. Reserves vary by lender, leverage, and loan size. Around 6 months of PITIA is common. PITIA means principal, interest, taxes, insurance, and association dues.

DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The complete DSCR loans guide walks through that review in full.

The second gate: rent

A DSCR cash-out has two tests, not one. The loan amount is the lower of the value-based amount and the amount the rent can support. Picture a rental with strong equity but modest rent. The value test might allow a large loan, while the rent test allows a smaller one. The smaller number wins.

Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger coverage opens better pricing and leverage.

Clearing 1.00 is not the same as positive cash flow. The calculation compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it. A thin ratio after a cash-out leaves little room for any of those.

Seasoning changes the denominator

Inside the seasoning window, lenders often size a loan on the lower of your cost basis or the appraisal. After the window, they size on the appraisal. About 6 months is the common expectation across the network.

Seasoning is a guideline, not a law. A securitization diligence exhibit filed with the SEC shows one lender waiving title seasoning on a DSCR cash-out for an experienced investor. That is one lender’s file, not a market rule. It does show that seasoning rules vary by guideline and sometimes bend.

Side by Side: Where Each Cap Binds

Where the Rule Breaks

The formula is simple. The exceptions are where investors get surprised.

An undrawn line still counts. CLTV counts the amount you plan to borrow, per the Yahoo Finance explainer. A lender sizing the next loan generally counts the full credit limit, not just what you have drawn. On this network, at least 75% of the investment line is drawn at closing anyway.

Stacking has an order. A property with a 70% CLTV line cannot also take a 75% LTV cash-out on top of it. A cash-out replaces the first lien and leaves the line behind it. The combined balance must still fit the line’s ceiling. In practice, investors sequence them. They use the line for short-term needs, then refinance and pay the line off at closing. How a lender treats an existing line during a refinance varies by program, so confirm it before you apply.

A low appraisal shrinks the cash directly. If you plan a value-add rehab, the cash-out amount rides on the after-repair appraisal. An improvement may support a higher appraised value, depending on comps and underwriter review. When the appraisal lands under your estimate, the percent ceiling applies to the lower number.

An LLC cannot hold a HELOC. The equity-line programs need the individual borrower or a revocable living trust on title. A property already deeded to an LLC needs a vesting change before a HELOC, or a DSCR cash-out instead, subject to lender program eligibility.

Rental use can violate a line’s terms. A line written for an owner-occupied home can restrict renting the property out. This matters if you plan to move out and rent. Read the occupancy clause before you count on that line.

Lines can change after closing. A lender can reduce or freeze a credit line if the home’s value drops. A cash-out refinance does not work that way. The funds are fixed once the loan closes. A HELOC also has phases. The CFPB’s HELOC page gives a draw period of 10 years as an example, followed by a repayment period.

Some properties are not eligible at all. Manufactured homes, log homes, and barndominiums fall outside the network’s DSCR programs. The equity-line programs also exclude condotels, co-ops, and mixed-use properties.

Which Cap Fits Your Plan

Match the product to the money need. A line suits ongoing or uncertain costs, because you borrow only as needed. A cash-out suits a single large need, such as a down payment on the next property or a major rehab. Tax treatment varies; consult a qualified professional.

The cash-flow trade-off runs the opposite way for each. A cash-out reprices the whole balance, which raises the payment and lowers your DSCR coverage. A HELOC leaves the first loan untouched. It adds a second obligation and puts your personal debt-to-income ratio in play. Repeated cash-outs also mean closing costs each time. A line replenishes as you pay it down.

Use these questions to pick:

1. Is your credit at 700 or above? If not, an investment HELOC is likely off the table. Cash-out programs generally start lower.

2. Is the property in an LLC? If so, a DSCR cash-out is the more direct route.

3. Do you need more than $500,000? If so, the HELOC cap binds. A cash-out can go up to $3,000,000.

4. Does the rent cover the new payment? If coverage is thin, the rent test, not the equity, may be your real limit.

Check Your Own Number in Three Steps

1. Take the appraised value and multiply it by the ceiling for your occupancy and product.

2. Subtract every loan secured by the property, including any undrawn line.

3. Subtract closing costs and prepaids, or for a cash-out, confirm the rent also supports the new loan.

The result is a rough ceiling, not an offer. Credit, reserves, property type, and the final appraisal can all move it.
