First Lien HELOC, A Different Way to Use Your Equity

I keep running into investors who are equity rich and cash poor. They have a paid down mortgage or a fully owned property, and no easy way to turn that equity into a down payment or rehab budget without doing a full cash out refinance and resetting their whole loan.

A first lien HELOC is one way around that, and it does not get talked about nearly as much as a regular second position HELOC.

The basic idea

A normal HELOC sits behind your existing mortgage. Your mortgage is the first lien, your HELOC is the second lien, and if things ever go sideways, the mortgage lender gets paid first.

A first lien HELOC flips that. Instead of adding a second loan behind your mortgage, it replaces your mortgage entirely and becomes the primary loan on title. Say you own a $350,000 property free and clear. You open a first lien HELOC for $250,000, and that line is now your first position loan, with all the revolving flexibility of a HELOC attached to it.

Why that matters

Because it holds first position, lenders treat it with the same weight as a conventional mortgage. That usually means a lower rate than a second lien product, and often a higher limit, since the lender is not taking on the extra risk that comes with subordinate debt.

You still get the same draw and repay structure as any HELOC. Typically a 5 to 10 year draw period where you can pull funds, pay them down, and pull them again, with interest only payments during that stretch. Then a repayment period, often 15 to 20 years, where you pay principal and interest and cannot draw anymore.

Where investors are actually using this

A few patterns I have seen come up a lot. Funding a fix and flip down payment and rehab without tying up cash. Running a BRRRR strategy where the line gets drawn down for the purchase and rehab, then paid back once the property refinances. Covering construction overruns on a rehab that ran over budget. And using it as a bridge into a new business or acquisition when the business itself is too young to qualify for traditional financing on its own.

One thing worth flagging on the BRRRR side. If you have a second lien HELOC or home equity loan behind your mortgage, refinancing later usually needs a subordination agreement from that second lienholder, which can slow things down or fall through. A first lien HELOC skips that problem since there is no subordinate lien to deal with.

The real risk

This is still your home in first position. If you cannot make payments, foreclosure is on the table, same as with a regular mortgage. Rates are usually variable too, so run the math on what happens if your rate climbs 2 points. On a $150,000 balance, that can take an interest only payment from around $875 a month to $1,125, and that is before the repayment period even kicks in and principal gets added.

Qualifying also looks a lot like qualifying for a first mortgage. Most lenders want a 680 to 720+ credit score, debt to income under 43 to 45%, and combined loan to value usually capped somewhere around 80 to 90%. Investment properties and anything held in an LLC tend to get stricter terms.

Where I would think twice

If you already have a mortgage under 4%, converting it into a first lien HELOC means giving that rate up. In that case a second lien product or a smaller home equity loan behind your existing mortgage is probably the better move. This tool makes the most sense when your current mortgage rate is already high, or when you own the property free and clear and want maximum flexibility on how you access the equity.

I have used a version of this thinking on my own deals through Gap Funded, mainly layering a first lien HELOC with other unsecured pieces to cover a full capital stack without giving up equity or adding a second lien on the deal property. Happy to answer questions if anyone is weighing this against a straight cash out refinance or a second lien product.
