Say you're under contract on a house in Alpharetta, Milton, Johns Creek or Roswell, and the loan you need is a little over $832,750. That figure is the 2026 conforming loan limit, and anything you borrow above it is jumbo. You can handle that in two main ways. You can take one jumbo loan, or you can split the debt into a conforming first mortgage plus a smaller second lien, which is often called a piggyback. This jumbo vs piggyback loan comparison uses September 2026 rate data and a $1.1 million example to show which setup costs less and when the answer changes.
Short answer: At the September rates we checked, one jumbo loan had a lower monthly payment than a conforming first plus a fixed-rate second in both rate surveys. The piggyback came out ahead in only one case: it used an interest-only home equity line of credit (HELOC), and that rate can move.
What is the 2026 conforming loan limit in Fulton County?
The limit for a one-unit home in Fulton County is $832,750, the national baseline. The Federal Housing Finance Agency announced the 2026 limits on Nov. 25, 2025. The baseline went up $26,250 from $806,500 in 2025, following a 3.26% increase in FHFA's House Price Index from the third quarter of 2024 to the third quarter of 2025.
FHFA's high-cost ceiling is $1,249,125, but that doesn't help here. Georgia has no high-cost counties, so the conforming limit is $832,750 everywhere in the state. Fulton County's FHA limit for a one-unit home in the Atlanta-Sandy Springs-Roswell area is $718,750, which is lower still. If you need to borrow more than $832,750 in North Fulton, you're looking at a jumbo loan or some way to keep the first mortgage under the limit.
The 80-10-10 price ceiling
A classic 80-10-10 piggyback means 80% first mortgage, 10% second and 10% down. The first mortgage stays conforming only if the purchase price is at or below about $1,040,937, which is $832,750 divided by 0.80. Above that price, an 80% first mortgage goes over the limit. To keep the first loan conforming, you'd need a bigger down payment, a bigger second or both.
The example below uses a $1.1 million home with 20% down. The first mortgage is capped at $832,750, about 75.7% of the price, and a $47,250 second makes up the rest of the $880,000 total.
What is a piggyback loan?
A piggyback loan is a second mortgage (a fixed-rate home equity loan or a HELOC) that closes along with your first mortgage. Here, the point is to keep the first loan at or under the conforming limit so it doesn't become a jumbo.
If the first mortgage is a conforming loan sold to Fannie Mae, the second has to meet Fannie Mae's subordinate financing rules. The lender must disclose the second lien and count every lien in the combined loan-to-value ratio (CLTV). The second has to carry a market rate of interest, and its payments must at least cover the interest, so the balance can't grow (no negative amortization). The guide also limits balloon terms. Ask your lender how those limits apply to the second they're offering.
Are jumbo rates higher than conforming rates right now?
Not reliably. In September 2026, the answer depended on which survey you looked at.
-
MBA Weekly Survey, week ending Sept. 4: The Mortgage Bankers Association reported an average 30-year fixed jumbo rate of 6.74%, down from 6.76%, with 0.63 points. The average 30-year conforming rate was 6.85%, up from 6.79%, with 0.67 points. In this survey, jumbo was cheaper.
-
Mortgage Research Center, Sept. 15: Fortune reported a 30-year jumbo rate of 7.125% and a 30-year conforming rate of 7.044%. In this data, jumbo cost slightly more.
-
Mortgage Research Center, Sept. 14: Money.com showed jumbo at 7.03% (7.05% APR) and conforming at 6.91%, one day earlier. That's a reminder that daily figures move.
These surveys sample lenders on different days in different ways, and MBA's averages include points. Mixing them gives a misleading answer. For example, pairing MBA's jumbo rate with MRC's conforming rate makes jumbo look much cheaper than either survey shows on its own. Compare jumbo and conforming within the same survey, and then compare both against your own Loan Estimates.
MBA's averages also assume an 80% loan-to-value ratio. In a piggyback, the first mortgage sits at a lower loan-to-value (about 76% in our example), so it may be priced differently. A jumbo with only 10% down is often harder to find or priced higher, and none of the sources we checked published a 90% loan-to-value jumbo rate. If that's your situation, get a real quote.
How much does the second mortgage cost?
More than either first mortgage. Bankrate's Sept. 9 averages put home equity loans at 8.13% overall: 8.13% for a 5-year term, 8.28% for a 10-year term and 8.22% for a 15-year term. The average HELOC rate the same day was 7.26%.
That leaves a choice. A home equity loan has a fixed rate and repays principal on a schedule, so the payment is higher but predictable. A HELOC starts cheaper, especially if you pay only interest, but the rate floats and paying interest only does nothing to reduce what you owe.
Jumbo vs piggyback loan: the monthly payment math
Example: a $1,100,000 North Fulton home with 20% down, or $880,000 borrowed. Every loan uses a 30-year fixed first mortgage. Payments are principal and interest only, so they leave out property taxes, homeowners insurance, points and lender fees. These are our own calculations from the rates cited above. The second-lien rates come from Bankrate in both columns because neither mortgage survey publishes second-lien rates.
| Structure | MBA rates (week ending Sept. 4) | MRC rates (Sept. 15) | | --- | --- | --- | | One jumbo loan, $880,000 | $5,702 at 6.74% | $5,929 at 7.125% | | Conforming first, $832,750 | $5,457 at 6.85% | $5,565 at 7.044% | | Plus $47,250 second, 15-year fixed at 8.22% | $458 | $458 | | Piggyback total, fixed second | $5,915 | $6,023 | | Difference | Jumbo lower by about $213 | Jumbo lower by about $94 | | Plus $47,250 HELOC at 7.26%, interest only | $286 | $286 | | Piggyback total, interest-only HELOC | $5,743 | $5,851 | | Difference | Jumbo lower by about $41 | Piggyback lower by about $78 |
Two points on reading the table:
-
The fixed-second piggyback pays down debt faster. Part of that extra $213 or $94 a month goes toward paying off the $47,250 second over 15 years. The monthly gap is real cash flow, but not all of it is extra cost.
-
The HELOC advantage is fragile. The $78 savings in the MRC column depends on a variable rate and on not paying down principal. If the HELOC rate rises, or you start repaying the balance, the advantage can disappear. With MBA rates, jumbo wins even against the interest-only HELOC.
Rates change daily, so re-run these numbers with your own quotes before you decide.
When does a piggyback loan make sense?
A piggyback can be the better choice in a few situations:
-
Your jumbo quote carries a real premium. If the jumbo rate a lender offers you is clearly above its conforming rate, the math can tip toward splitting the loan.
-
You expect to pay off the second quickly. A year-end bonus or the sale of a prior home could clear the second lien soon after closing. If so, the higher second-lien rate matters less. Check for prepayment terms before counting on this.
-
A jumbo lender's rules don't fit you. Jumbo lenders can require more cash reserves or set stricter credit standards. A conforming first may be easier to qualify for.
One jumbo loan tends to win in these situations:
-
Jumbo pricing is at or below conforming pricing, as it was in MBA's Sept. 4 survey.
-
You want a fixed rate on the whole loan and would choose a fixed-rate second anyway.
-
You'd rather have one loan, one set of lender fees and no second lienholder to deal with later.
Does a piggyback change Georgia closing costs?
Very little, with one exception for HELOCs. Georgia charges an intangible recording tax of $1.50 per $500 (or fraction of $500) of a note's face amount, capped at $25,000 per note. It applies to long-term notes, meaning any principal is due more than three years out, under Rule 560-11-8-.03. The Clerk of Superior Court collects it, and lenders may pass the cost to the borrower.
The tax is charged note by note, but in our example the totals come out almost the same:
-
One jumbo loan of $880,000: $2,640
-
Piggyback: $2,499 on the $832,750 first plus $142.50 on the $47,250 second, or $2,641.50
The exception: under Rule 560-11-8-.13, a HELOC is taxed on the full credit line, whether or not you draw on it. If a lender sets up a $100,000 line when you only need $47,250, the tax on that line would be $300 instead of $142.50. Ask for a line sized to what you need.
Georgia's real estate transfer tax is based on the purchase price, not the loan, so it's the same under either structure.
Hidden costs and risks to check
-
Points. MBA's averages included 0.63 points on jumbo loans and 0.67 on conforming loans. One point is 1% of the loan amount, so on these balances each structure's average comes to roughly $5,500 in points. Your quotes may carry more or fewer.
-
Two sets of lender fees. A piggyback means two loans, and the second can come with its own origination and closing charges.
-
Refinancing gets harder. To refinance the first mortgage later, you'll need the second lienholder to agree to stay in second position (called subordination), or you'll need to pay the second off. That can add time and paperwork.
-
HELOC rate changes. A variable second can reprice upward, and an interest-only balance stays the same until you start paying principal.
-
Jumbo reserves. Jumbo lenders may require more cash left over after closing. Ask what counts toward reserves before you commit.
How to compare jumbo and piggyback quotes
-
Pull current North Fulton sales data for your area from FMLS, Redfin or Atlanta Realtors, so your price and down payment assumptions match the market you're buying in.
-
Ask for a Loan Estimate on both structures, on the same day and at the same loan-to-value, ideally from the same lender and from at least one other.
-
Compare the total monthly payment, including the second lien's payment under the terms you'd actually choose.
-
Compare points, lender fees and total cash to close, including intangible recording tax on each note or line.
-
Estimate your cost over five years, in interest, points and fees, rather than looking only at the first month's payment.
-
If a HELOC is part of the plan, ask how the rate is set, how often it can change and when principal payments start.
-
Ask each lender about reserve requirements, prepayment terms on the second and how subordination works if you refinance.
Neither structure is always cheaper, and nobody can tell you where rates are headed between now and your closing date. In September 2026, one jumbo loan beat a piggyback with a fixed-rate second in both surveys we checked. A piggyback made sense mainly when it used an interest-only HELOC or when the buyer had a specific reason to split the loan. Run the same comparison with your own Loan Estimates, and let those numbers decide.
