Home Equity Explained
A first lien HELOC pays off your mortgage and takes its place. Instead of a fixed loan with a set monthly payment, your home is financed by a line of credit. Your income goes in and pays the balance down, your bills come out and draw it back up, and interest is charged on the balance day by day.
The honest part first: your entire home balance moves to a variable rate, nothing forces the balance down, and the line can be frozen if your home's value drops significantly. It can work well for a homeowner with steady income who spends well below it every month. For most other homeowners, a fixed rate mortgage or a regular second lien HELOC is the safer choice.
Read This First
A regular HELOC puts a variable rate on the amount you borrow on top of your mortgage. A first lien HELOC puts it on everything you owe on the home. The rate is a public index, most often the prime rate, plus a margin set in your agreement. When the index rises, the cost of your entire balance rises with it. Federal rules require a maximum rate to be stated, so ask for that cap in writing and decide whether you could live with it.
A fixed rate mortgage pays itself down on a schedule whether you think about it or not. A first lien HELOC does not. Every dollar you pay down can be drawn back out, so the balance shrinks only in the months you spend less than you earn. A vacation, a car repair or a slow month for a business owner shows up directly as a higher home balance. Without a written budget and the habit of sticking to it, the balance can sit still for years.
Federal rules allow new draws to be stopped or the limit lowered in specific cases, including a significant drop in your home's value or a material change in your finances. On a first lien HELOC the line is where your cash flow lives, so money you deposited may not be available to draw back out when you need it most. Keep an emergency fund in a separate account, not only inside the line.
Every line has a draw period. When it ends, borrowing stops and the remaining balance is repaid on a schedule, so the payment can rise. Know the length of the draw period and the repayment terms before you sign.
If you are holding a low fixed mortgage rate, stop here. Replacing it with a variable rate line rarely makes sense, because you give up a rate that cannot rise in exchange for one that can. A second lien HELOC or a home equity loan lets you borrow against equity and keep your mortgage. See HELOCs in Georgia and HELOC vs home equity loan.
How It Works
The idea is simple: money that would sit in a checking account earning little or nothing spends part of each month lowering the balance on your home. Whether that adds up to anything meaningful depends almost entirely on what is left over at the end of the month, which is what the example below shows.

One Month, Worked Out
A Georgia homeowner owes $300,000 on the home. Take home pay is $9,000 a month, deposited on the first of the month. Spending is $7,500 a month, paid out evenly. To show the structure alone, the regular monthly payment is left out.
| Point in the month | First lien HELOC balance |
|---|---|
| Day 1, before the paycheck | $300,000 |
| Day 1, after the $9,000 deposit | $291,000 |
| Day 15, after about half the spending | about $294,750 |
| Day 30, after all $7,500 of spending | $298,500 |
| Average balance for the month | about $294,750 |
Illustration only, not a quote, an offer or an approval. Balances are rounded, assume spending is spread evenly over a 30 day month and leave out interest, fees and the scheduled payment. Your interest method, rate and terms are set in your agreement.
The bottom line: a first lien HELOC rewards a monthly surplus and punishes a monthly shortfall. If spending matched income in this example, the balance would end the month right where it started, still on a variable rate. Be wary of any pitch that promises a mortgage paid off in a fraction of the time without showing your own income and spending.
Side by Side
Three ways to finance a home with equity in it, and how each behaves once the papers are signed.
| Criteria | First lien HELOC | Fixed rate mortgage | Second lien HELOC |
|---|---|---|---|
| Your current mortgage | Paid off and replaced by the line | Paid off and replaced by the new fixed loan | Stays in place with its rate and payment |
| Rate type | Variable on the whole home balance | Fixed for the life of the loan | Variable on the line only, in most programs |
| How the balance goes down | Only when deposits beat spending | On a schedule, every payment | Depends on the program and your payments |
| Access to paid down money | Can be drawn again during the draw period | Needs a refinance or a separate loan | Can be drawn again during the draw period |
| Discipline required | High: the line refills as fast as it empties | Low: the schedule does the work | Moderate: only the line is flexible |
| Freeze risk | Affects your main cash flow account | None after closing | Affects the line, not the mortgage |
| Tends to fit | Steady income, a reliable surplus, and no low fixed rate to protect | Anyone who wants a payment and a rate that do not move | Homeowners who want to keep their mortgage and borrow for a project |
| Structures vary by program and are subject to underwriting approval. Rates, fees and terms are confirmed in writing during your review. | |||

Not sure which side you are on? A loan expert can compare a first lien HELOC with a fixed rate refinance, a second lien HELOC and a cash out refinance on your actual numbers, and will tell you plainly when the answer is to keep what you have.
Georgia Only
Georgia charges an intangible recording tax of $1.50 for every $500, or part of $500, of a long term note secured by Georgia real estate, about 0.3%, with a cap of $25,000. Since July 1, 2025, a note is long term when any principal is due more than 62 months out, which covers nearly every first lien HELOC. For a line of credit, Georgia's rule charges the tax on the full line amount when the security deed is recorded, whether you draw it or not, and later draws within that limit owe nothing more.
| Line amount | Georgia intangible tax |
|---|---|
| $100,000 | $300 |
| $300,000 | $900 |
| $500,000 | $1,500 |
Figures use the statutory rate of $1.50 per $500 of the line. Your actual closing costs come from your HELOC disclosures and closing documents.
Because a first lien HELOC also pays off your mortgage, the line has to be large enough to cover that payoff, so this tax is usually larger than on a second lien line. Georgia has a refinance exemption when the original lender refinances its own note; your closing attorney confirms whether any part of your line qualifies.
The Supreme Court of Georgia has held that only a licensed Georgia attorney may close a real estate transaction, so a first lien HELOC closes with a Georgia attorney or under an attorney's supervision, and the attorney or settlement fee is part of your closing costs.
On your primary home, federal law generally gives you until midnight of the third business day after closing to cancel when a line of credit refinances your existing mortgage. Saturdays count; Sundays and federal holidays do not. No money is released until that window closes.
A HELOC is open end credit, so it does not come with the Loan Estimate and Closing Disclosure you may remember from buying the home. Federal rules require HELOC specific disclosures instead, including how the variable rate works, the maximum rate and the fees. Read them side by side with any fixed rate offer before you choose.
Qualifying
First lien HELOCs are offered by a smaller set of programs than regular mortgages, and their requirements tend to be stricter because the line carries your whole home balance. The underwriter generally reviews:
Rates, the margin, fees, the draw period and the line limit are confirmed in writing during your review. Availability depends on the program and on underwriting approval, and the honest answer for some homeowners is that a fixed rate mortgage serves them better.
Questions, Answered
It is a home equity line of credit that sits in first position on your home. It pays off your current mortgage and replaces it, so the line becomes your only mortgage. You can draw from it and pay it down during the draw period, and interest is charged on the balance you carry.
A regular HELOC usually sits in second position behind your existing mortgage, which stays in place with its own rate and payment. A first lien HELOC replaces that mortgage, so your whole home balance moves into the line and its variable rate.
Interest is usually figured on the balance each day, and the exact method is written in your agreement and disclosed when the line opens. When income is deposited, the balance drops and so does the interest for those days. When bills are paid from the line, the balance rises again. The rate is variable, built from a public index such as the prime rate plus a margin.
Only if you consistently bring in more than you spend. Depositing a paycheck lowers the balance until the money is spent, but most of that comes back out as bills are paid. The lasting drop each month is your surplus, the money left after spending. The same surplus paid as extra principal on a fixed rate mortgage also shortens the loan, without moving the whole balance to a variable rate.
Yes, in limited cases set by federal rules. New draws can be stopped or the limit lowered if your home's value falls significantly, if your finances change in a way that makes repayment doubtful, or if you default on a material term. On a first lien HELOC that matters more, because money you deposited to pay down the line may not be available to draw back out. Keep an emergency fund outside the line.
Borrowing stops and the remaining balance is repaid over the repayment period. The payment can rise at that point, and it still moves with the rate. Ask for the draw period, the repayment terms and the maximum rate in writing before you choose.
Georgia's intangible recording tax is $1.50 per $500 of the line, about 0.3%, capped at $25,000. For a line of credit it is charged on the full line amount at recording, whether you draw it or not. A $300,000 line owes $900. Georgia has a refinance exemption when the original lender refinances its own note, and your closing attorney confirms whether any part of your line qualifies.
On your primary home, federal law generally gives you three business days after closing to cancel when the line refinances your existing mortgage. No money is released until that window closes. Your closing package explains the exact deadline in writing.
Anyone protecting a low fixed mortgage rate, anyone whose spending regularly matches or beats their income, anyone with irregular income and thin savings, and anyone who would rather have a payment that does not change. For most of those homeowners, a fixed rate mortgage, a second lien HELOC or a home equity loan is the safer fit.

A home equity line of credit is secured by your home, and failure to meet the obligations of the line can put the home at risk. First lien HELOCs generally carry variable rates, so rates and payments can increase up to the maximum rate stated in the agreement. Advances may be suspended or the credit limit reduced in the cases permitted by federal law. Closing costs and fees may apply. Consult a qualified tax professional about the tax treatment of interest. Program terms may change before you apply; once a line opens, terms change only as the agreement and federal law allow.
