Current jumbo guidelines, updated from one source.
Four cards and two tables carry every figure a jumbo file turns on, drawn from one source built on the wholesale lane sheets: amount, credit, leverage, and ratio in the cards; structure, occupancy, reserves, and appraisal rules lane by lane in the tables.
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
A 660 score is where the program starts, and the lane table shows what each higher floor buys: a longer term, an interest-only period, or a different amount range. The score sets the lane; the lane sets everything else, from leverage to reserves.
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
50% is the ceiling on most of the lanes, as generous as a conforming loan; the lanes that stop lower are listed lane by lane in the table below. The automated finding, where the lane uses one, decides how much of the room a particular file gets.
| Lane | Structure | Credit | Max DTI | Max leverage | Loan amounts | Occupancies |
|---|---|---|---|---|---|---|
| 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 B | 30-year fixed | 660+ | 50% | 89.99% CLTV | above the conforming limit to $3M | primary, second, investment |
| Lane C | 30-year fixed | 720+ | 50% | 80% CLTV | above the conforming limit to $3.5M | primary, second |
| Lane D | 30-year fixed (660+); 40-year fixed and 40-year fixed with 10-year interest-only (680+, 80 percent LTV, to $2M) | 660+ | 50% | 89.99% LTV | above the conforming limit to $5M | primary, second, investment |
| Lane E | 30-year fixed | 660+ | 50% | 90% LTV | $400,000 to $3.5M | primary, second, investment |
| Lane F | 30-year fixed | 700+ | 45% | 80% LTV | $600,000 to $3M | primary |
| 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 E | to $2M per the automated finding; $2M–$3M six months in addition; over $3M twelve months in addition | above $2M | No | Yes |
| Lane F | per the automated finding | one appraisal | No | No |
| Lane G | over $2M eighteen months in addition to the automated finding | one appraisal for purchases to $3M and refinances to $2M; two for refinances over $2M | No | No |
| 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.
Current jumbo snapshot · updated October 1, 2026 · on most lanes a jumbo loan begins one dollar above the conforming limit for the county, which the FHFA resets each year and a Lendmire loan officer confirms, and two lanes start at a stated dollar floor instead · amounts at or below the limit otherwise belong to the conventional program · Lendmire is a broker, never the lender.

What a jumbo loan is — and how the file is qualified.
The difference between a jumbo loan and a conforming loan is who sets the rules. Above the limit there is no agency guide to follow, only the lender’s lane sheet, and the lane sheet is stricter in two places: reserves and appraisals. The cards below explain each of the four pieces for an Ann Arbor buyer.
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. An Ann Arbor file that straddles the line is sized both ways before an offer.
Credit, ratios, and the lane
The score does not merely open the program on a jumbo file; it chooses the lane, and the lane sets the leverage, the amount range, and the reserves. A buyer close to a higher floor sometimes gains more from a short wait than from any other change to the file.
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 an Ann Arbor buyer sees the cash the file needs beyond the closing table.
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 Ann Arbor jumbo purchases carry at least one full appraisal.
None of this is a decision. Two appraisals can land apart, the lane’s rate is set at lock, the automated finding can add reserves, and the county’s conforming limit decides whether the loan is jumbo at all. What stays fixed is the structure the calculator reproduces: price, down payment, loan, lane, payment.
Ann Arbor’s market in figures — and how jumbo fits.
A jumbo loan is sized against the top of a local market, and these are Ann Arbor’s numbers from the U.S. Census Bureau: how many households own, what a typical home is worth, and what households earn. The jumbo range sits above the median, and the figures show how far above it the market reaches.
Citywide figures provide general market context, not an appraisal or an income calculation. The Census describes the market; the file describes the borrower. The funding lender appraises one specific home and adds a second appraisal above the threshold. It also documents one income and verifies one set of reserves.
Data sources: U.S. Census Bureau — ACS 5-Year (2024) housing and population estimates, including tenure, home values, gross rents, and household income.
Distinct Ann Arbor neighborhoods, distinct jumbo files.
Six kinds of Ann Arbor property, six versions of the same program: the cards below describe the housing stock, the price range, and the jumbo question that comes up most often in each.
Second homes and pied-à-terre purchases
Ann Arbor second homes above the limit sit on the lanes that allow the occupancy, with more reserve months than a principal residence and, on some lanes, cash-out limited or capped. The home must be for the owner’s use rather than a rental business. About 55% of Ann Arbor’s households rent — roughly 27,544 renter households on the latest Census estimate.
Newer luxury infill and new construction
New luxury construction in Ann Arbor appraises more easily than nearby one-off homes, so the question is the amount: well above the limit, the lane’s reserve months rise, two appraisals apply above the threshold, and the structure chosen sets the lane. The median owner-occupied home value in Ann Arbor runs near $453,400 on the latest Census estimate.
Two-to-four-unit homes above the limit
The multi-unit jumbo file in Ann Arbor 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. Ann Arbor is home to about 122K people.
High-rise and luxury condominiums
The condominium question on an Ann Arbor jumbo file is which lanes the project leaves open, and the lender settles it through its project review. Once settled, the leverage, the reserves, and the appraisal count follow the lane as they would on a house. Median household income in Ann Arbor sits near $82,212 on the latest Census estimate.
Estate properties
The largest Ann Arbor 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. Roughly 22,955 Ann Arbor households own their homes on the latest Census estimate — 45% of all households, the pool a jumbo purchase joins.
Close-in architect-designed homes
The architect-designed homes on Ann Arbor’s best close-in streets are hard to value: few comparable sales, wide price ranges, and finishes that comparable sales may not support. On a jumbo file above the threshold two different appraisers value the home independently. On a home in Ann Arbor 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.
Each Ann Arbor submarket has its own appraisal story, and on a jumbo file the appraisal is where that story is told, twice when the amount is large enough. The lane rules are the constants.
Four ways Ann Arbor buyers put a jumbo loan to work.
A good use of a jumbo loan is one its shape fits: a loan amount above the limit, a score at or above the lane floor, reserves in hand, and a property that two appraisers can value. Four common Ann Arbor uses follow.
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 Ann Arbor buyer who wants one brings the lane’s reserves and expects the lender’s own project review.
Buy above the limit with a modest down payment
The high-leverage jumbo purchase is the program’s defining use: a loan well above the limit, a down payment smaller than the old twenty-percent rule, and a file read on reserves and appraisals as much as on the score. An Ann Arbor buyer at the floor score reaches it when the amount, the ratio, and the reserves also fit.
Finance a larger multi-unit home
An Ann Arbor multi-unit purchase above the limit uses the investment-occupancy lanes when the buyer lives elsewhere, with the jumbo appraisal rule. Reserves follow the lane’s investment column and the amount band. Owner-occupied two- to four-unit homes follow principal-residence rules.
Refinance or take cash out above the limit
An Ann Arbor owner with a jumbo balance refinances on the same lanes, rate-and-term to the lane’s leverage or cash-out to a lower ceiling and a cash cap on some lanes. Most jumbo lanes start one dollar above the conforming limit and two start at a stated dollar floor; one lane takes a conforming amount on a cash-out at lower leverage after six months.
Estimate the payment on an Ann Arbor price before requesting a quote.
Enter an Ann Arbor price, the down payment, the structure, and the occupancy, and the calculator returns the loan and its leverage, the payment for the structure chosen, the payment after an interest-only period, taxes and insurance, the lanes that fit the combination, the reserve months the amount band calls for as a dollar figure, and the appraisal count. The rate field holds the weekly Freddie Mac conforming benchmark as a market reference, never a jumbo quote.
Ann Arbor jumbo payment estimate
Seeded at a jumbo-range price for Ann Arbor; every field updates the result, the lanes, and the reserves as you type.
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 Ann Arbor, 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.
Most purchases above the conforming limit can be structured three ways, and the structures differ more than the headlines suggest: a single jumbo loan on a lane, a conforming high-balance loan where the county’s limit reaches that high, or a conforming first mortgage paired with a second lien that keeps the first under the limit.
Jumbo, high-balance conforming, or a conforming first with a second lien.
The jumbo loan fits the Ann Arbor 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 an Ann Arbor 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.
Two loans instead of one: a conforming first under the county limit and a HELOC second for the rest. It keeps the agencies’ rules on the larger loan and avoids the jumbo reserve and appraisal rules, at the cost of a variable-rate second lien and two payments. An Ann Arbor loan officer runs it beside the jumbo lane. 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. An Ann Arbor loan officer runs all three on the same numbers before recommending one.
What to prepare for an Ann Arbor scenario review.
What a lender reads on an Ann Arbor 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.
Check these before leaning on any number for Ann Arbor: the reserves the amount band requires, the appraisal count, the lane the structure and score allow, the conforming limit, the ratio ceiling, the occupancy, and any cash-out cap.
Use these checks to keep the Ann Arbor file clean and fundable.
Three things to settle before an Ann Arbor review: whether the reserves meet the lane’s months at this amount, whether the amount crosses the two-appraisal threshold, and which lane the structure and score allow.
- Count the reserves: retirement and business funds count at the lane’s rules.
- Plan the appraisals: appraisal waivers are not available on the prime lanes.
- Mind the ratios: the lane’s ceiling is read on the full housing payment, with reserves a separate test.
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. An Ann Arbor 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 an Ann Arbor 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.
The ratio ceiling for the structure
Enter income in the calculator to see where an Ann Arbor scenario lands against the ceiling for the structure chosen; the lane table shows each lane’s figure, the ratio is measured on the full payment plus every other obligation, and the loan officer confirms which ceiling applies.
Condominiums: warrantable or not
An Ann Arbor 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
Two of the lanes carry a fixed dollar floor of their own, shown in the lane table, rather than the county limit. For the rest, one dollar over the limit is the floor, and the loan officer checks the county’s current figure before the offer is written.
From an Ann Arbor pre-approval to keys in hand.
A jumbo purchase runs in a fixed order: pre-approval on the lane, the reserves, and the ratio; contract and one or two appraisals; underwriting that verifies the reserves and the income against the lane; and closing on the structure chosen. Here is that order for an Ann Arbor buyer.
Pre-approval
An Ann Arbor 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 appraisal step is where an Ann Arbor jumbo file differs most from a conforming one: no waiver on the prime lanes, a second appraisal above the threshold, and a careful read of comparable sales on a home that may have few. A short value re-sizes the loan or renegotiates the price.
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. An Ann Arbor buyer signs the note and the security instrument and occupies the home as the stated occupancy requires.
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 Ann Arbor 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 an Ann Arbor buyer at the price in hand.
Licensed, consumer-purpose, in writing
What this page shows are the lane parameters; what a specific Ann Arbor loan gets is a written set of terms from a licensed loan officer after the review, on the lane chosen and the structure selected. Lendmire is a broker, never the lender.

Ann Arbor jumbo loan FAQs
Plain answers to the questions Ann Arbor 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 a mortgage whose amount runs past the conforming limit the FHFA sets for the county, so the agencies will not buy it and a private lender writes it on its own lane rules. You need one in Ann Arbor when the loan amount, not the price, exceeds the county’s limit and you do not want a larger down payment or a split structure to stay under it.
How large can a jumbo loan be in Ann Arbor?
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 an Ann Arbor 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?
Every lane has its own floor, and the lowest one is in the snapshot. An Ann Arbor buyer at that floor can reach the top-leverage lane when the amount, the ratio, and the reserves also fit; a stronger score opens more lanes and the choice then turns on structure and cost.
How much will a jumbo loan lend against the home?
It is a lane question. The lane table shows each lane’s maximum beside its credit floor and amount range, and the loan officer reads all three together before sizing the down payment on an Ann Arbor purchase.
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.
What debt-to-income ratio does a jumbo loan allow?
As generous as a conforming loan on most lanes, tighter on the structures that carry more payment risk later. The lane table shows each lane’s ceiling, and the automated finding, where the lane uses one, decides how much of the room an Ann Arbor file gets.
What happens after my Ann Arbor 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?
The lane table lists them: fixed structures with the most leverage, adjustable structures with an initial fixed period, one at the full ratio and one below it, and the interest-only period with the tightest ratio in the table.
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. An Ann Arbor 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.
How is income documented on a jumbo loan?
With a two-year history for each source. The loan officer reads the picture before the lane is chosen, because the structure and the ratio ceiling depend on income that will continue.
