Investment Property HELOC Requirements on an Offer Letter

The Quick Read: An investment property HELOC supports an offer only after the line is approved and the cash is drawn into your own account, because sellers treat a drawn balance as cash and an approval letter as unfunded capacity. On Lendmire’s wholesale network, an investment line runs to 70% CLTV, up to $500,000, with a 700 minimum credit score and at least 75% of the line drawn at closing. The line also has to sit on a property you already own, never on the one you are bidding on.

• The document that travels with the offer is a bank statement showing drawn funds, not the HELOC approval.
• Investment lines cap at 70% CLTV and $500,000, and 700 is a hard credit floor.
• Title must be in an individual’s name or a revocable living trust. LLC-held property does not qualify for the line.
• The DSCR purchase loan is a separate file. It is judged on rent against its own payment, and the lender will want the HELOC funds sourced.
• The line’s payment sits outside the coverage ratio but still comes out of real cash flow.

What “Offer Letter” Means Here

The phrase has two readings. In most investor use, it is the purchase offer sent to a seller, with proof of funds attached. Less often, it is an employment offer letter a borrower hopes will stand in for income on a line application. This article is mainly about the first reading.

For the purchase-offer reading, the HELOC is only a funding source. It does not replace the purchase loan. The new property still needs its own financing or a true cash purchase. This is where most confusion starts. Investors treat the line as the deal, when it is really the down payment.

How a Seller Reads a HELOC

A seller or listing agent wants to see money that exists today. A drawn line is cash. An undrawn line is capacity, and some sellers accept it while many do not. The approval letter proves the line exists, but it does not prove the funds are in your account.

For that reason, the sequence matters:

1. The line is approved and closes against equity in a property you already own.

2. At least 75% of the line is drawn at closing on the network’s investment HELOC program, so cash lands in your account as part of the process.

3. You move the funds to an account in your own name, which leaves a clean paper trail.

4. You attach a current account statement to the offer. It shows your name, the institution, the date and the balance.

A statement does not have to say how the funds got there. It only has to show they are available. A cropped screenshot or a missing institution name invites questions from the agent. A balance that lands exactly on the offer price does the same.

An offer should not be presented as a cash offer unless the money is actually in hand. Investors do fund cash-style offers with HELOC money, as this BiggerPockets discussion of using HELOC funds on a cash offer shows. The funds just have to be real when the offer goes in.

The Network’s Investment HELOC Requirements

Across the wholesale network, the investment-property line is narrower than the primary-residence line. These are the figures that matter for an offer, and all of them are subject to lender guidelines and full file review.

Two points deserve a closer look. First, credit above 700 buys eligibility, not leverage. A 720 score and a 700 score both reach the same 70% CLTV ceiling on an investment line. Second, the cap is $500,000. Because of that cap, an investment line normally runs on an automated valuation instead of a full appraisal, though a borrower can request a full appraisal.

For example, NerdWallet’s guide to HELOCs on investment property reports typical credit scores around 720, maximum LTVs up to 80% at some lenders, and at least 20% equity. Those are market-wide statistics. On this network, an investment line stops at 70% CLTV.

Debt-to-income is also reviewed on the line itself. The maximum is 50%, and the qualifying payment is calculated on the interest-only payment at the maximum draw. Business bank accounts need a 680 minimum for deposit analysis, but because investment lines already floor at 700, that is never the binding constraint.

Pricing floats through both the draw and the repayment period and never converts to fixed. The payment you carry on the line can move for the life of the line.

A Worked CLTV Example

Consider a rental you own. Say its value is established by the automated valuation, and the existing first mortgage equals 45% of that value. The 70% CLTV ceiling leaves 25% of the value as the most the line can add. That is the maximum, and the line size is also capped at $500,000, whichever is lower.

Now say your target purchase needs a down payment larger than that line. You have a shortfall. The options are to put in cash from savings, to bring a lower-priced target, or to use a DSCR purchase program with a smaller down payment.

Purchase leverage on most DSCR files runs 75% to 80% LTV, which means 20% to 25% down. Select high-leverage programs reach 85% LTV with a score around 700 or better, subject to lender guidelines. Each added point of leverage shrinks the down payment the HELOC has to cover. It also raises the payment the rent must carry.

How the DSCR Purchase Lender Treats HELOC Money

A DSCR purchase is underwritten separately from the line. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The lender looks at rent against the new loan’s payment, taxes, insurance and any HOA dues, and does not run your personal debt-to-income. This is covered in more depth in the complete DSCR loans guide.

That does not mean the HELOC is invisible. Three things come up on the purchase file:

• Sourcing. The lender wants to see where the down payment came from. A draw from a line on another property, moved into your account, leaves a clear trail.
• Seasoning. Some programs want the funds to have sat in the account before the file is submitted. Others look mainly at the sourcing trail. This varies by lender.
• Borrowed-funds treatment. Down payment, closing costs and reserves are three separate tests. A program can accept borrowed funds for one and reject them for another. A HELOC balance is a liability, so it often cannot serve as reserves, even when it can serve as down payment. One BiggerPockets thread on HELOCs as a down payment describes this same split.

Reserves vary by lender, leverage, loan size and transaction type. Around 6 months of PITIA is common. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived, and loans above that size typically step up to about 9 months. If your reserves would be funded by the same line, ask the program before you draw.

Coverage is its own test. A 1.00 ratio is where select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Clearing 1.00 is not the same as positive cash flow, since repairs, vacancy, management, utilities and capex sit outside the calculation.

Two Obligations, One Rent Check

The line payment does not enter the DSCR ratio, but the rental still has to support both loans in practice. The new property carries its own payment, and you also service the line on the other property. The line is interest-only during the draw, so nothing reduces principal in that period.

The CFPB’s explanation of a HELOC notes that payments are often significantly higher once the repayment period starts. The CFPB’s HELOC brochure adds that some plans allow interest-only payments during the draw period, which means you pay nothing toward principal. An investor planning a long hold should model the step-up at the end of the 5-year draw, when the 25-year repayment begins. Because pricing floats, the model should include some movement either way.

Where the General Rule Breaks

An undrawn line. Seller discretion decides. An undrawn line can also be frozen or reduced by the line’s own lender if circumstances change. With 75% drawn at closing on the network’s investment line, the undrawn question is mostly limited to the remaining portion.

A lien on the target property. If the line sits on the property you are buying, that is not a cash purchase. A new purchase also has no rent history to underwrite. Use equity from a different property.

Entity-titled property. Title on this line must be held by the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead, subject to program terms.

Property type. Single-family, 2-4 units, PUD, townhome and condominium, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural zoning are not.

Prior credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, foreclosure history follows a 7-year path, and a deed-in-lieu, pre-foreclosure or short sale follows a 4-year path.

Exposure. A borrower is limited to three lines, and an investor with more than 15 financed properties is not eligible. Combined exposure caps depend on the program.

Availability. The HELOC product is offered only in 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA and WA. That is narrower than the 41-market DSCR footprint. A property listed for sale, or listed in the past 60 days, is ineligible in NC, PA, TN, TX and WA.

HELOC or DSCR Cash-Out: Which Fits the Offer?

Some investors reach for a HELOC when a DSCR cash-out refinance would serve better. The two products behave differently.

The HELOC works well when you need a flexible draw and own the property personally. The cash-out refinance works better when the property sits in an LLC, when you want a fixed structure, or when the borrower’s own debt load would crowd the HELOC’s 50% DTI limit. More on the second route is in Lendmire’s guide to cash-out refinancing an investment property.

Key Terms Defined

CLTV: Combined loan-to-value, which adds the existing mortgage balance and the new line and divides by the property value.

Draw period: The stretch when you can borrow against the line, which on the network’s investment program is 5 years of interest-only payments.

Proof of funds: A current account statement showing money available in your name.

Approval letter: A document confirming the line exists, which a seller does not treat as cash.

Seasoning: The time funds have sat in your account, which some purchase programs look at.

Offer letter: Either a purchase offer sent to a seller or an employment offer a borrower shows a lender; this article mainly covers the first.
