Current jumbo guidelines, updated from one source.
The block below is the jumbo program reduced to the figures that decide a file, read from Lendmire’s single guideline source and refreshed on this page when the wholesale lanes change: the amount ceiling, the credit floor, the leverage, and the ratio, followed by the lane table and the reserve and appraisal rules lane by lane.
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; 80% on five of the nine lanes
Loans on the top lane go up to 90%, which means a modest down payment on a loan well above the conforming limit. Five of the lanes stop at 80%, the adjustable and interest-only lanes among them, as the lane table below shows. The down payment is the first number a loan officer sizes.
On six of the nine lanes; lower on the other three
The ratio ceiling is 50% on most lanes, lower on the structures that carry more payment risk later, and it is read against the full housing payment: the new principal and interest with taxes, insurance, and any association dues. Reserves sit beside the ratio as a second test.

|---|---|---|---|---|---|---|
| Lane A | 30-year fixed, 40-year fixed, 40-year fixed with 10-year interest-only | 700+ | 50% | 89.99% CLTV | above the conforming limit to $5M | primary, second, investment (cash-out: primary and second only) |

| Lane G | 5-, 7- and 10-year adjustable-rate | 680+ | 45% | 80% LTV | above the conforming limit to $5M | primary, second, investment |
| Lane H | 30-year fixed with a 10-year interest-only period and 20-year amortization | 700+ | 43% | 80% LTV | above the conforming limit to $5M | primary, second |
| Lane I | 7- and 10-year adjustable-rate with expanded ratios | 660+ | 50% | 80% LTV | above the conforming limit to $3M | primary, second |
| 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 |
| Lane D | to $2M per the automated finding; over $2M six months in addition | above $2M | Yes | Yes |

| Lane H | to $1M twelve months in addition to the automated finding; over $1M twenty-four months | one appraisal for purchases to $3M and refinances to $2M; two for refinances over $2M | No | No |
| Lane I | primary purchase to $3M 6–18 months; second home to $3M 12–18; cash-out primary to $1.5M 12 (cash to $250,000), $1.5M–$2M 15 (cash to $500,000); second home cash-out 12–18 months | above $1.5M | 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.
Every Dearborn jumbo file is matched to a lane and then qualified on that lane’s rules. The automated finding, where the lane uses one, applies the rules; it does not soften them. Below, the four pieces a buyer needs to understand: the threshold, the credit and ratio, the reserves, and the appraisals.
For the program overview, see Lendmire’s jumbo loan program, or the statewide guide at Jumbo Loans in Michigan; for the conforming limit by county, see the FHFA.
Above the conforming limit
The threshold matters because it changes the rulebook: below it the agencies’ guides govern and the loan can be sold to them; above it the lender’s lane sheet governs and the loan stays with the lender or its investors. A Dearborn file that straddles the line is sized both ways before an offer.
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
Reserves are months of the full housing payment left in verified accounts after closing, and they scale with the loan. Several lanes defer to the automated finding up to a threshold amount, then add months above it. Reserve-table lanes set the months by occupancy and amount band, and the largest amounts ask for the most. A Dearborn jumbo buyer plans reserves with the down payment.
One appraisal, or two
Above the lane’s threshold a jumbo loan needs two appraisals from two different appraisers; below it one appraisal serves. The thresholds sit in the lane table, and appraisal waivers are not available on the prime lanes or on one fixed lane, so most Dearborn jumbo purchases carry at least one full appraisal.
The calculator runs this on a Dearborn 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.
Dearborn’s market in figures — and how jumbo fits.
Three Census figures frame a Dearborn 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.
Market context only. Income sets the ratio, value sets the loan, and the amount sets the reserves and the appraisal count. The Census describes the first two for the market; the file supplies all three for the borrower.
Data sources: U.S. Census Bureau — ACS 5-Year (2024) housing and population estimates, including tenure, home values, gross rents, and household income.
Distinct Dearborn neighborhoods, distinct jumbo files.
A Dearborn waterfront estate, a close-in architect-designed house, and a large new build in a planned community are three different jumbo files: different comparable sales, different appraisal counts, different lanes. The six submarkets below show the range.
Two-to-four-unit homes above the limit
The multi-unit jumbo file in Dearborn is a narrower lane choice: investment occupancy is allowed on several lanes but not all, and the loan officer prices the file on each before choosing. Dearborn is home to about 107K people and sits within the Detroit-Warren-Dearborn, MI area.
Estate properties
The largest Dearborn files are placed on the lanes whose maximum amount reaches the price, priced on each, and documented fully: two years of income, every account behind the reserves, and two appraisals. About 32% of Dearborn’s households rent — roughly 11,597 renter households on the latest Census estimate.
High-rise and luxury condominiums
A Dearborn unit above the limit is a jumbo file with the project review added. Established buildings usually pass; buildings with rental programs, heavy commercial space, or litigation move to the non-warrantable lanes, which carry their own leverage and reserves. Median household income in Dearborn sits near $65,324 on the latest Census estimate.
Newer luxury infill and new construction
On new construction in Dearborn 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 Dearborn runs near $218,800 on the latest Census estimate.
Second homes and pied-à-terre purchases
A pied-à-terre in Dearborn 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 25,098 Dearborn households own their homes on the latest Census estimate — 68% of all households, the pool a jumbo purchase joins.
Close-in architect-designed homes
A distinctive Dearborn house is a distinctive appraisal, and on a jumbo loan the lender wants the value supported twice above the threshold. Buyers plan for a second appraisal in the timeline and for a value that may land under the contract price. On a home in Dearborn 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.
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 differ by lane, and each Dearborn file is matched to one.
Four ways Dearborn 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 Dearborn borrowers to it most.
Choose the structure that fits the plan
Structure is a jumbo decision in a way it rarely is on a conforming loan: a forty-year term lowers the payment, an adjustable structure trades certainty for an initial period, and an interest-only period keeps the payment low for a decade before amortization. The calculator shows the Dearborn payment under each.
Finance a larger multi-unit home
The larger multi-unit Dearborn home is financed on jumbo terms when the loan outruns the limit: investment leverage and reserves on the lanes that allow the occupancy, rents counted toward qualifying, and the appraisals the amount calls for.
Finance a second home or an investment property
Jumbo lanes finance the Dearborn home the buyer does not live in full time, and the lane table shows which ones: second homes on most lanes, investment property on several, each with its own reserve months and a cap on cash-out where the lane allows it.
Buy a condominium the agencies will not finance
Non-warrantable condominiums are a jumbo specialty on two lanes: resort buildings with rental programs, projects with heavy commercial space, buildings in litigation. The Dearborn buyer who wants one brings the lane’s reserves and expects the lender’s own project review.
Estimate the payment on a Dearborn price before requesting a quote.
This is what a Dearborn jumbo purchase costs each month under each structure, with the two things conforming calculators skip: the reserve months the amount band requires, turned into dollars at the payment, and whether the amount crosses the two-appraisal threshold on the lanes that fit. Edit any field; the rate shown is the weekly Freddie Mac average and not a quote.

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 Dearborn, 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 Michigan (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. On most lanes the conforming limit for the county decides whether a loan is jumbo at all; two lanes start at a stated dollar floor instead. Licensed in sixteen states for consumer mortgages.
Same purchase, three ways to structure it.
The loan amount, the county’s conforming limit, the score, the reserves available, and the expected length of the loan decide which structure wins. Here are the three, one next to the other.
Jumbo, high-balance conforming, or a conforming first with a second lien.
The jumbo loan fits the Dearborn buyer whose loan amount sits well above the limit, who holds the reserves the lane requires, and who wants a single mortgage with a structure chosen to fit the plan. A buyer just over the limit with thin reserves is where the alternatives compete.
Where the county allows it, the high-balance conforming loan keeps a Dearborn purchase inside the agencies’ guides, with their insurance rules and their lighter reserves; where the loan runs past even the high-cost figure, the jumbo lane is the only single-loan route. See Lendmire’s conventional loan program.
The split structure fits the Dearborn 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.
Choose by amount and by reserves: far above the limit points to a jumbo lane; under a high-cost county’s figure points to high-balance conforming; just over the limit with thin reserves points to the split structure. A Dearborn loan officer runs all three on the same numbers before recommending one.
What to prepare for a Dearborn scenario review.
What a lender reads on a Dearborn jumbo loan, and what you can have ready before anyone asks.
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 Dearborn 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 Dearborn 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 above the county’s conforming limit.
- Count the reserves: retirement and business funds count at the lane’s rules.
- Plan the appraisals: a larger down payment can keep the amount under the threshold.
- Match the lane: the structure, score, leverage, amount, and occupancy pick the lane together.
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 Dearborn buyer should know the lane’s rule before counting any account.
One appraisal or two, by lane threshold
Above the lane’s threshold two appraisals from two different appraisers are required; below it one appraisal serves. Appraisal waivers are not available on the prime lanes. A Dearborn buyer above the threshold plans the second appraisal into the contract timeline and the budget.
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 Dearborn 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.
Condominiums: warrantable or not
A Dearborn condo over the limit is financed on any lane for warrantable projects, and on two lanes if not: resort buildings with rental programs, heavy commercial space, or litigation. The lender reviews the project itself; dues enter the ratio.
The conforming limit, and whether the loan is jumbo
A loan is jumbo only above the county’s conforming limit, which the FHFA resets each year. A Dearborn buyer near the line is sized both ways, as conforming under it (high-balance where the county has that range) or as jumbo above it, and the lighter file usually wins.
From a Dearborn pre-approval to keys in hand.
Strip away the lane rules and the Dearborn 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
Start with score, income, down payment, reserves, structure, and occupancy. A Lendmire loan officer confirms the county’s conforming limit, matches the file to lanes that fit, prices each, compares the jumbo lane with a high-balance conforming loan and a split structure on the same numbers, and puts the terms in writing.
Contract and appraisals
With the contract signed, the lender orders one appraisal, or two from two different appraisers where the amount crosses the lane’s threshold. Seller contributions are checked against the lane, and a condominium’s project documents are collected for the lender’s review.
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
At closing the loan is funded on the lane and the structure chosen, the escrows for taxes and insurance are set up, and the reserves are left in the accounts that were verified. A Dearborn buyer signs the note and the security instrument and occupies the home as the stated occupancy requires.
A brokerage that reads every lane.
Lendmire never lends. It reads a Dearborn file against the jumbo lanes, the conforming high-balance loan, and the conforming-plus-HELOC structure, matches the file to the one that fits, and keeps the reserves, the appraisals, and the ratio ceiling in front of the buyer before anything is signed.
Every lane, one set of numbers
Before any recommendation, the Dearborn file is matched to every lane it fits and priced on each, then run against a high-balance conforming loan and a split structure on the same numbers. The buyer sees the payment, the reserves, and the cash to close for each.
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 Dearborn buyer at the price in hand.
Licensed, consumer-purpose, in writing
Sixteen states license Lendmire to broker consumer mortgages. An owner-occupied jumbo loan carries the full consumer disclosures, and the figures a Dearborn buyer relies on, from the lane’s leverage to the reserve months to the final terms, arrive in writing from a licensed loan officer.

Dearborn jumbo loan FAQs
Plain answers to the questions Dearborn buyers ask most about jumbo loans, in the order they usually ask them.
What is a jumbo loan, and when do I need one?
A jumbo loan is non-conforming by amount: one dollar or more above the county’s conforming limit, placed with a wholesale jumbo program on that program’s terms. A Dearborn buyer at the top of the market usually needs one; a buyer near the line has alternatives, compared on this page.
How large can a jumbo loan be in Dearborn?
As large as the snapshot’s ceiling on the lanes that reach it, subject to the leverage, the reserves, and two appraisals above the threshold. For a Dearborn purchase beyond even that figure, the loan officer looks to the investor and portfolio programs.
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 up to the leverage in the snapshot, which keeps the down payment modest on a loan well above the limit. The seven hundred twenty-plus, ARM and interest-only lanes stop at eighty percent. These pages do not say whether mortgage insurance applies; your loan officer confirms the structure for your lane.
How much do I need in reserves for a jumbo loan?
More than a conforming loan asks: the lane names the months by amount band, the months rise above the thresholds, and second homes and investment property carry more than a principal residence. Liquid accounts count in full; retirement and investment accounts count at the lane’s haircut.
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 Dearborn 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.
What is the conforming loan limit in Dearborn?
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 Dearborn loan near the line is sized both ways.
Can I get a jumbo loan after a bankruptcy or foreclosure?
The lanes follow agency-style seasoning, and a strong rebuilt profile with deep reserves is the combination that qualifies afterward. Gather the discharge or transfer dates before the review; they decide whether a Dearborn file can be written now.
What happens after my Dearborn offer is accepted?
Your Dearborn contract goes to the lender, the appraisal or appraisals are ordered, and underwriting follows. The usual detours are two values that land apart or reserves that need sourcing; a loan officer keeps the timeline honest.
Is cash out allowed with a jumbo refinance?
Cash-out is available on most lanes, capped by amount and by leverage, with the caps differing lane by lane. A Dearborn owner whose first mortgage is worth keeping usually compares a second lien first; one whose first mortgage should be replaced anyway uses the cash-out lane.
The Dearborn jumbo file, read across every lane and explained plainly.
A Dearborn jumbo purchase starts with three questions: the amount against the limit, the structure, and the reserves. Lendmire answers them, prices the lanes, and writes up the one that fits.
