Current jumbo guidelines, updated from one source.
One guideline source feeds every number here, and the page updates when the lane sheets do. The four headline figures are the best cell across lanes; the tables underneath show which lane carries which, because no single lane carries all four at once.
From one dollar over the conforming limit to $5,000,000
The ceiling is $5,000,000 for a purchase or rate-and-term refinance on the largest lanes; cash-out runs lower. The floor is the conforming limit for the county, one dollar above it, except on two lanes that start at a fixed amount whatever the limit, as the lane table shows.
Lanes open at the floor and step up by leverage and structure
Credit on a jumbo file is a lane question: 660 opens the program, and each structure and leverage combination carries its own floor in the lane table. With more than one borrower the lane’s underwriting system reads the scores the way the agencies do.
Loan-to-value on the top lane; eighty percent on the rest
Up to 90% on the top lane means a modest down payment on a loan well above the conforming limit; eighty percent is the ceiling on the adjustable and interest-only lanes and on the lane with the highest credit floor. The down payment is the first number a loan officer sizes.
On the fixed lanes; lower on the adjustable and interest-only lanes
The ratio ceiling is 50% on the fixed lanes, lower on the structures that carry more payment risk later, and it is read against the full payment, interest-only payments included at the interest-only amount. Reserves sit beside the ratio as a second test.

| Lane | Reserves | Two appraisals | Non-warrantable condos | Temporary buydowns |
|---|---|---|---|---|
| Lane A | primary purchase to $5M: 6–12 months; second home to $3M: 9–12; investment to $2.5M: 12; cash-out: 9 months minimum | above $2M | No | No |
| Lane B | to $2M per the automated finding; over $2M six months in addition; reserve table: primary purchase to $3M 6–12 months, second home to $3M 9–12, investment to $1.5M 12; cash-out primary to $2M 6–12, second to $2M 9–12, investment to $1.5M 12 | above $1.5M | Yes | Yes |
| Lane C | primary purchase to $2M 6–9 months, over $2M 24 months; second home to $2M 6–9; cash-out primary to $2M 6–9, second to $2M 6 | above $2M | No | No |

Structures across the nine lanes: 30-year fixed; 40-year fixed (manual underwrite on one lane); 40-year fixed with a 10-year interest-only period; 5-, 7- and 10-year adjustable-rate; 30-year fixed with a 10-year interest-only period and 20-year amortization. Purchases, rate-and-term refinances, and cash-out refinances; principal residences, second homes, and investment property where the lane allows. The headline figures are the best cell across lanes; no single lane carries all of them, and a Lendmire loan officer matches the file to the lane that fits.

What a jumbo loan is — and how the file is qualified.
A jumbo loan is a mortgage the agencies will not buy because the amount runs past the conforming limit, so a private lender keeps it on its own terms. Those terms are the lane sheets: credit floor, ratio ceiling, leverage, amount range, reserves, and appraisals. The four cards below take a South Fulton file apart along those lines.
For the program overview, see Lendmire’s jumbo loan program, or the statewide guide at Jumbo Loans in Georgia; for the conforming limit by county, see the FHFA.
Above the conforming limit
Two lanes in the table start at a fixed dollar floor instead of the conforming limit, which lets a South Fulton loan sit on a jumbo lane even where the county limit is higher; the rest begin one dollar above the limit. The ceiling is the lane’s maximum amount, and cash-out runs lower than purchase on the largest lane.
Credit, ratios, and the lane
Ratios on a jumbo lane are read the way the agencies read them: the full housing payment plus every other monthly obligation against gross income, up to the lane’s ceiling. The interest-only lane counts the interest-only payment and still carries the tightest ceiling, because the payment rises when the period ends.
Reserves by amount and occupancy
On a jumbo file the reserves are the second down payment. The lane sheet names the months by amount band and occupancy, the interest-only lane asks for a year or two, and the calculator turns the months into a dollar figure at the payment entered so a South Fulton buyer sees the cash the file needs beyond the closing table.
One appraisal, or two
The appraisal rule follows the amount, not the price, so a South Fulton buyer with a larger down payment can sometimes stay under the two-appraisal threshold on a lane while financing the same home. The loan officer sizes the loan with that threshold in view.
The calculator runs this on a South Fulton scenario and adds the two things a conforming calculator never shows: the reserve months the amount band calls for, as a dollar figure at the payment, and whether the amount crosses the two-appraisal threshold on the lanes that fit.
Where South Fulton’s larger loans are written — and how jumbo fits.
Three Census figures frame a South Fulton jumbo file. Ownership says how deep the market is, the median value says where the jumbo range begins relative to the typical home, and household income says what ratio a large payment produces.
Read the figures as backdrop. A high median value means more of the market prices past the conforming limit and more files are jumbo; a modest median value means the jumbo range is the top slice of the market. The lane rules do not move; the share of homes they apply to does.
Data sources: U.S. Census Bureau — ACS 5-Year (2024) housing and population estimates, including tenure, home values, gross rents, and household income.
Distinct South Fulton neighborhoods, distinct jumbo files.
The house and its price decide the file as much as the borrower. These South Fulton submarkets differ in the property types, the occupancies, and the amounts a typical buyer carries, which is what the cards below describe.
Estate properties
The largest South Fulton files are placed on the lanes whose ceiling reaches the amount, priced on each, and documented fully: two years of income, every account behind the reserves, and two appraisals. On a South Fulton home priced well above the median, a jumbo loan at the program’s top leverage finances up to 90% of the value — the balance of the price is the down payment, before reserves and closing costs.
Second homes and pied-à-terre purchases
A pied-à-terre in South Fulton is a second-home jumbo file: most lanes reach it, the reserves run deeper, and the structure wanted picks the lane. A loan officer prices the lanes that fit before the offer. Roughly 28,844 South Fulton households own their homes on the latest Census estimate — 72% of all households, the pool a jumbo purchase joins.
Newer luxury infill and new construction
On new construction in South Fulton the appraisal is usually uneventful and the arithmetic decides: which lanes reach the amount, what reserves the band calls for, and whether the ratio carries the price at the structure chosen. The median owner-occupied home value in South Fulton runs near $309,800 on the latest Census estimate.
Two-to-four-unit homes above the limit
South Fulton’s larger multi-unit homes outrun the conforming limit and finance on the jumbo lanes that allow investment property, with the deepest reserve months in the table, rents documented toward the ratio, and two appraisals above the threshold. South Fulton counts a population near 110K.
Close-in architect-designed homes
Value drives the South Fulton jumbo file on a one-of-a-kind home: the loan is sized on the lower of two appraisals above the threshold, and a larger down payment is the usual answer when the appraisals land apart. About 28% of South Fulton’s households rent — roughly 11,479 renter households on the latest Census estimate.
High-rise and luxury condominiums
The condominium question on a South Fulton jumbo file is which lanes the project leaves open, and the lender settles it before the appraisal. Once settled, the leverage, the reserves, and the appraisal count follow the lane as they would on a house. Median household income in South Fulton sits near $82,324 on the latest Census estimate.
Neighborhood sets the price, the comparable sales, and often the occupancy; the lane sheet sets the rest. The leverage limits, the reserve months, the appraisal thresholds, and the ratio ceilings apply identically on every South Fulton file.
Four ways South Fulton buyers put a jumbo loan to work.
The jumbo loan does one thing the conforming program cannot: it finances the home whose loan amount is too large for the agencies. Within that, it buys principal residences, second homes, and investment property, refinances them, and takes cash out. These are the uses that bring South Fulton borrowers to it most.
Buy a condominium the agencies will not finance
A South Fulton condominium project that fails the agency review is still financeable on a jumbo lane that allows non-warrantable projects; the lender reviews the project on its own terms, and the leverage follows the lane.
Buy above the limit with a modest down payment
For a South Fulton purchase above the limit, the top lanes carry the leverage the conforming program carries below it; the price of that leverage is the reserve months, the lane’s credit floor, and, above the threshold, a second appraisal from a second appraiser.
Choose the structure that fits the plan
A South Fulton buyer who expects to sell or refinance within a few years looks at the adjustable lanes; one who wants the lowest early payment looks at interest-only; one who wants certainty takes the fixed lanes. Each sits on its own row in the table with its own rules.
Refinance or take cash out above the limit
Cash-out on a jumbo lane is capped by amount and by leverage, and the caps differ lane by lane; a South Fulton owner weighing cash-out against a second lien has the loan officer run both, since keeping a first mortgage worth keeping and adding a line behind it often costs less.
Estimate the payment on a South Fulton price before requesting a quote.
The program’s own arithmetic on your South Fulton inputs: price less the down payment, amortized for the structure, with escrows added, the lanes matched, and the reserves and appraisals read from the lane table. The actual rate, payment, and costs come in writing from a licensed loan officer.
South Fulton jumbo payment estimate
The starting figures are a South Fulton price in the jumbo range with ten percent down on a thirty-year fixed. Replace them with yours.
Editable benchmark: 7.28% as of October 1, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a jumbo loan quote.
Illustrative starting assumptions: a $1,000,000 price in the jumbo range for South Fulton, ten percent down on the top-leverage lane, a thirty-year fixed structure at the current Freddie Mac conforming benchmark, property taxes and insurance estimated for Georgia (U.S. Census Bureau). Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conforming benchmark, a market reference and not a jumbo loan quote; jumbo rates are set by the lender and the lane at lock and differ from the conforming benchmark. An adjustable-rate scenario is shown at the benchmark for the whole term; the rate after the initial period is unknown. Reserve months and appraisal counts follow the lane sheet for the amount band; the automated finding may require more. Taxes, insurance and dues are editable estimates; closing costs are not included. The conforming limit for the county decides whether a loan is jumbo at all. Licensed in sixteen states for consumer mortgages.
Same purchase, three ways to structure it.
The alternatives put the jumbo loan in perspective: the conforming high-balance loan has the agencies’ rules and limits, the split structure has two loans and two payments, the jumbo loan has one loan on the lender’s terms. The comparison below is written for a South Fulton buyer weighing all three.
Jumbo, high-balance conforming, or a conforming first with a second lien.
The program’s strengths are reach, leverage, and structure; its demands are reserves and appraisals. A South Fulton buyer at the top of the market usually ends up here because the conforming program stops at the county limit and the split structure only reaches so far.
A high-balance conforming loan is a conventional loan with a bigger ceiling, available only where the county’s limit reaches that high. It carries the agencies’ credit standard and insurance rules, and where the loan fits under the figure the file is lighter than a jumbo file. See Lendmire’s conventional loan program.
The split structure fits the South Fulton buyer whose loan would barely cross the limit: the first mortgage stays conforming, the second lien covers the gap, and the combined payment is often competitive with a single jumbo loan. The second lien is a HELOC with its own draw and repayment periods. See Lendmire’s home equity line of credit.
Where each one fits: the jumbo lane for the loan well above the limit, the high-balance conforming loan where the county’s figure reaches high enough, and the conforming-plus-HELOC structure for the loan just over the line with a buyer who prefers agency terms on the larger piece.
What to prepare for a South Fulton scenario review.
A jumbo file is documented more fully than a conforming one, because no agency stands behind it; here is what a South Fulton scenario review typically draws on.
This is a general preparation guide, not a universal checklist. The selected lender may request additional information based on the transaction, the property, the lane, the automated finding, and the income picture. Nothing here is legal or tax advice.
Local details that can change the loan.
What moves a South Fulton file most often: the reserves, the appraisals, the lane, the conforming limit, the ratio ceiling for the structure, the occupancy, the condominium review, and the cash-out cap.
Use these checks to keep the South Fulton file clean and fundable.
Before asking for a quote, know three answers: how many reserve months the amount calls for, how many appraisals it needs, and whether the loan is jumbo at all under the county’s limit.
- Count the reserves: the lane names the reserve months by amount band and occupancy.
- Plan the appraisals: appraisal waivers are not available on the prime lanes.
- Document the income: business funds need a letter or analysis showing no impairment.
Reserves scaled to the amount
What counts is settled by the lane: liquid accounts in full, retirement and investment accounts at a haircut, business funds with documentation showing the business is not impaired. Gifts may cover part of the picture on some lanes. A South Fulton buyer should know the lane’s rule before counting any account.
One appraisal or two, by lane threshold
The threshold follows the loan amount rather than the price, so a South Fulton buyer can sometimes stay under it with a larger down payment on the same home. The loan officer sizes the loan with the threshold in view, and the lane table shows where each lane draws it.
Income documentation on a larger file
Self-employed South Fulton buyers carry the most paper on a jumbo file: two years of personal and business returns, year-to-date statements, and a reading of how the business is doing. Business funds used for the down payment or reserves need a letter or analysis showing the withdrawal does not impair the business.
Cash-out caps and seasoning
Cash-out refinances on jumbo lanes carry their own ceilings: a lower maximum amount than purchases on the largest lane, a cap on the cash itself on two lanes, and deeper reserve months. A South Fulton owner with a large first mortgage weighs the cash-out against a home equity line that leaves the first mortgage alone.
Which lane the file lands on
No single lane carries every headline figure, which is why the loan officer reads the whole table before sizing a South Fulton file. The lane that fits the leverage may not fit the structure; the lane that fits the structure may cap the amount lower; the file is placed where all the pieces fit at once.
From a South Fulton pre-approval to keys in hand.
Strip away the lane rules and the South Fulton process is any mortgage process; the lane match, the reserve verification, the appraisal count, and the lender’s own review are what make it jumbo. The four steps below show where each enters.
Pre-approval
A South Fulton jumbo pre-approval is a sizing exercise with the lane table open: the amount against the limit, the leverage against the lane, the reserves against the band, the ratio against the structure. The loan officer puts the result in writing for the offer.
Contract and appraisals
The South Fulton contract sets the price and the timeline; the appraisals set the value and, above the threshold, there are two of them. The lender confirms the project review where the home is a condominium and the lane before underwriting begins.
Underwriting
The underwriter verifies the file against the lane: the income over two years, the assets and the reserve months, the credit and any seasoning, the occupancy, and the property. The automated finding is confirmed where the lane uses one. Conditions are issued, documented, and cleared before the approval is final.
Closing
The South Fulton closing applies the lane’s structure: a fixed payment, an initial fixed period on an adjustable loan, or an interest-only payment for the period chosen. The buyer takes the keys, and the lender keeps the loan or places it with its investors.
A brokerage that reads every lane.
Lendmire is a mortgage brokerage licensed for consumer lending in sixteen states, and on a jumbo loan that buys three things: the file read against every lane rather than one lender’s single product, the reserves and the appraisal count explained before an offer is written, and the terms in writing from a licensed loan officer.
Every lane, one set of numbers
The comparison printed on this page is run for real on every South Fulton file: the jumbo lanes beside the high-balance conforming loan beside the conforming first with a HELOC second, and the written terms follow from it.
Reserves and appraisals explained before the offer
Reserves and appraisals are the program’s demands, and Lendmire explains both first rather than last: how many months, from which accounts, how many appraisals, and what each means for a South Fulton buyer at the price in hand.
Licensed, consumer-purpose, in writing
The license covers the state the South Fulton home is in, the disclosures follow the consumer rules, and the terms are committed to paper. The lane figures on this page come from one guideline source built on the wholesale sheets, with the lender unnamed.

South Fulton jumbo loan FAQs
Plain answers to the questions South Fulton buyers ask most about jumbo loans, in the order they usually ask them.
What is a jumbo loan, and when do I need one?
Think of it as the conventional loan’s larger sibling with a different rulebook: lane sheets instead of agency guides, reserves scaled to the amount, and appraisals counted by the amount. A South Fulton loan officer checks the county’s limit first, because the same price can be conforming in one county and jumbo in the next.
How large can a jumbo loan be in South Fulton?
The lane table shows each lane’s range. A South Fulton buyer whose loan sits inside more than one lane’s range is placed on the lane whose structure, leverage, and credit floor also fit, and priced on each.
What credit score do I need for a jumbo loan?
The lanes open at the floor in the snapshot and step up by structure and leverage: the top-leverage lanes sit at the floor, the forty-year and interest-only structures ask for more, and the lane with the lowest leverage asks for the most. The score chooses the lane, and the lane sets the leverage, the amount range, and the reserves.
How much will a jumbo loan lend against the home?
The top lane lends the snapshot’s figure against the value; most other lanes lend eighty percent. The leverage a South Fulton file actually gets depends on which lane the structure, the amount, and the occupancy put it on.
How much do I need in reserves for a jumbo loan?
Reserves are the second down payment on a jumbo file. The months depend on the amount and the occupancy, the accounts that count depend on the lane, and a South Fulton loan officer confirms both before the offer so the closing does not drain the accounts the lane expects to see afterward.
What happens after my South Fulton offer is accepted?
The file moves into appraisal and underwriting, and the calendar is set by the appraisals and the conditions the underwriter adds. No page can promise a date, and this one does not.
What loan structures are available on a jumbo loan?
Fixed for certainty, adjustable for a defined horizon, interest-only for the lowest early payment, forty-year for a lower payment over a longer term. Each changes the lane, the leverage, and the ratio ceiling, which is why structure is settled early on a South Fulton file.
Can I use a jumbo loan for a second home or an investment property?
Second homes on most lanes, investment property on several, each with deeper reserves. A South Fulton buyer financing a weekend home or a rental above the limit sits on a lane that allows the occupancy, and the loan officer prices the file there.
Should I use one jumbo loan or a conforming first with a HELOC second?
Run both. The split structure keeps the first mortgage conforming, which means agency terms and possibly an appraisal waiver, while the HELOC covers the gap at a variable rate with its own draw and repayment periods. The single jumbo loan means one payment and one set of lane rules.
What is the conforming loan limit in South Fulton?
There is a county limit, revised annually, and some counties carry a high-balance range above the standard figure. The loan officer confirms it at pre-approval, and a South Fulton loan near the line is sized both ways.
