HELOC

2 min read
Short answer
A home equity line of credit is a revolving loan secured against a property. During the draw period the borrower can take and repay funds repeatedly, usually paying interest only. When the draw period ends, the balance amortises over the repayment period — and the payment increase at that transition is what catches borrowers.

A home equity line of credit is a revolving loan secured against a property. It behaves more like a credit card than a mortgage during its first phase, and like a mortgage afterwards.

Two phases#

The draw period. The borrower can take funds up to the limit, repay them, and take them again. Payments are frequently interest-only, and frequently at a variable rate.

The repayment period. No further draws. The outstanding balance amortises over the remaining term.

The transition is the danger#

The moment that produces distress, and it arrives on a known date.

A borrower who has been paying interest only on a substantial balance suddenly faces a payment covering principal and interest over a shorter remaining term.

The increase is frequently not marginal. It can be a multiple of what was being paid, arriving on a household that had budgeted around the smaller figure for a decade.

Because HELOCs were widely originated in particular periods, those transitions arrive in waves — which is why they show up as a cluster in delinquency data rather than as scattered individual events.

Anyone with a HELOC should know the date the draw period ends and what the payment becomes. Both are in the loan documents.

Priority and subordination#

A HELOC is usually a second lien, recorded after the first mortgage.

That produces the subordination problem on any refinance. Paying off and replacing the first mortgage would leave the new loan recording behind the HELOC — so the HELOC holder must agree to subordinate, in a recorded agreement.

It requires a request, an approval and time. A refinance timeline that did not allow for it is a timeline that slips.

Lines can be frozen#

Worth knowing before relying on undrawn availability.

Lenders can commonly suspend or reduce a line where the property's value falls significantly or the borrower's circumstances deteriorate.

That happened widely after 2008, to borrowers who were current and who had been treating the undrawn balance as an emergency reserve. It was not.

In a foreclosure#

A HELOC in second position is extinguished as security by a first mortgage foreclosure.

The holder's remedies are the same as any junior lienholder: reinstate the first before the sale under Minn. Stat. 580.30, or record a notice of intent to redeem and redeem afterwards in priority order.

Most do neither, which is why most second-position HELOCs simply disappear at a sheriff's sale.

Common questions

What happens when the draw period ends?
The line closes to new draws and the outstanding balance amortises over the repayment period. Because the draw period was frequently interest-only, the payment can increase sharply — often by a multiple rather than a margin.
Does a HELOC affect refinancing my first mortgage?
Yes. Refinancing the first requires the HELOC holder to subordinate, since the new mortgage would otherwise record behind it. That takes a request, an approval and a recorded agreement, and it needs building into the timeline.
Can a lender freeze my line?
Commonly yes, where the property's value falls significantly or the borrower's circumstances change. Lines were frozen widely after 2008, and borrowers relying on undrawn availability discovered it was not guaranteed.
