The Quick Read: Jumbo rules are set lender by lender, not by one federal rulebook. A new professional on contract income with student loans is judged on three things: how the lender counts the income, how it counts the student-loan payment, and how much cash sits behind the file. A signed contract can support income in some cases, and a deferred loan usually still shows up in the ratio. Everything below is subject to lender guidelines and full file review, and none of it is a commitment to lend.
What Makes a Loan “Jumbo”?
The loan amount decides it, not the price and not your income. A jumbo loan starts one dollar above the conforming limit for the county and the number of units. The FHFA 2026 CLL Addendum shows how that limit is built: a national baseline set under federal law, with high-cost counties allowed up to 150% of it. The same loan can be jumbo in one county and conforming in the next.
Jumbo payment estimate
The starting figures are an example price in the jumbo range with ten percent down on a thirty-year fixed. Replace them with yours.
Editable benchmark: 7.40% as of October 15, 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, ten percent down on the top-leverage lane, a thirty-year fixed structure at the current Freddie Mac conforming benchmark, and property taxes and insurance estimated at typical national rates. 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.
Here’s the catch for new professionals. Fannie Mae and Freddie Mac can’t buy a jumbo loan, so their guides don’t govern it. Each wholesale jumbo lane sets its own overlays. The CFPB conventional loans page says as much: rules vary by lender, and borrowers usually need good credit and a high down payment.
Across the wholesale programs Lendmire places files with, the envelope looks like this. The headline lane starts at a 660 decision score. Leverage reaches 90% on that lane, and several lanes reach 89.99% combined LTV while the rest stop at 80%. Loan amounts run to $5,000,000 on the largest lanes. Fixed lanes carry a 50% ratio ceiling, the adjustable lanes 45%, and the interest-only lanes 43%. Those are program figures, subject to lender guidelines. Lendmire is a mortgage broker and arranges these loans through wholesale lenders. It does not lend.
Key Terms Defined
Conforming limit: The county loan cap above which a loan can’t be sold to Fannie Mae or Freddie Mac.
DTI (debt-to-income ratio): Your monthly debts divided by your monthly gross income.
Qualifying income: The income the lender actually counts, after it is documented and judged likely to continue.
Imputed student-loan payment: A payment the lender calculates, often from the balance, when the actual payment is zero or unclear.
Reserves: Cash left after closing, measured in months of the full housing payment.
Overlay: A lender’s own rule that sits on top of the baseline guidelines.
How Do Lenders Count Contract Income?
They count what they can document and what they expect to continue. Federal ability-to-repay rules require the lender to verify the income it relies on with reliable third-party records, such as tax transcripts, filed returns, W-2s and payroll statements. The CFPB’s ability-to-repay compliance guide says that list isn’t exhaustive. Only the income used to qualify has to be verified.
Fannie Mae’s guide is a useful reference point for how the industry thinks, even though it doesn’t govern jumbo. It generally wants a two-year earnings history, and it allows less than two years when the latest returns show a full 12 months of self-employment income and the file supports prior income at the same level or higher. A 1099 contractor is generally treated as self-employed for documentation. A jumbo lane may be stricter or looser. Never assume either.
| Contract type | What usually proves it | Main risk |
|---|---|---|
| Fixed-salary offer | Signed offer, then paystub | Start date slips |
| W-2 contract, guaranteed hours | Contract plus payroll | Hours fall short |
| 1099 contractor | Returns or transcripts | Deductions shrink income |
| Per-diem or locum | Two-year history | Income varies |
| Commission or bonus pay | Averaged history | Often not counted early |
The Signed Offer Question
Can you buy before the new job starts? Sometimes. Fannie Mae’s employment offers or contracts rule requires a fully executed offer that names the employer, position, pay and start date. One path is limited to a purchase of a one-unit primary home on fixed base pay. The offer can’t come from a family member or someone with an interest in the sale. Variable pay and refinances fall outside it.
Whether a jumbo lane accepts a signed offer is a separate question, and it’s the first thing to settle before you write an offer on a house. In practice, some lanes want a paystub in the file. Some accept the contract with a verbal employment check. Some want more history.
How Do Lenders Count Student Loans?
They count a payment, and which payment they count is the biggest swing in the file. Fannie Mae’s monthly debt obligations rule is the reference model. On an income-driven plan, a documented actual payment of zero can qualify at zero. For deferred or forbearance loans, the lender may calculate a payment equal to 1% of the balance. Installment debts with more than 10 payments left generally count.
That is Fannie Mae’s rule. A jumbo lane may use its own method, and it may differ. Treat any claim that “jumbo uses 1%” as unverified until the lender confirms it in writing.
| Method | When it tends to apply |
|---|---|
| Actual payment on the credit report | Plan is active and payment is documented |
| Income-driven payment | Plan letter shows the current amount |
| Balance-based figure | Loan is deferred or payment is zero |
| Excluded | Someone else pays, with a documented history |
Student debt matters more on a jumbo because the housing payment is already large. On the fixed lanes the 50% ceiling applies to the whole stack: housing payment, student loans, cards, car. A balance-based figure on a large deferred balance can push a file over that ceiling when the actual payment would not.
A Worked Example
Picture a new attorney with a signed offer and a large deferred balance. The borrower puts 20% down on a jumbo-size loan. Counted at the actual income-driven payment, the ratio lands comfortably under 45%. Counted on a balance-based figure, the same borrower lands near 49%. Same person, same house, same income. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
What moved the result was the student-loan method, not the income. On a fixed lane with a 50% ceiling, that borrower may still fit. On an adjustable lane at 45%, probably not. On an interest-only lane at 43%, no. The lane choice and the loan structure matter as much as the borrower’s credit.
This is why a pre-application conversation about student-loan treatment beats shopping on price alone. The fixes are practical. Document the plan letter. Show the payment history. Ask which method the lane uses before the appraisal is ordered.
How Much Cash Do You Need?
More than a conforming buyer, and it scales with the amount. Down payment runs from 10% on the highest-leverage lane up to 20% on lanes that stop at 80%. Reserves are measured in months of the full payment, and they rise as the loan grows. The largest loans also trigger two appraisals above a lane’s threshold amount. The exact threshold is the lane’s, so ask for it up front.
For someone starting a job, add a second layer. Moving costs, licensing fees and the gap before the first paycheck all draw from the same account that has to show reserves. Cash that’s earmarked for the move can’t also count as reserves. Lenders look at the balance after closing.
Appraisals deserve a note. If the appraisal comes in below the price, you cover the gap or renegotiate. That risk is higher when the borrower is already stretched on the ratio. The federal rule on higher-priced mortgage loans does include one protection: when a second appraisal is required on certain quick-resale files, the lender can’t charge you for it.
Where the General Rule Breaks
A few named edge cases come up often with new professionals.
- Start date after closing. The longer the gap between closing and the first paycheck, the fewer lanes will accept the offer alone.
- Declining contract income. Lenders tend to use the lower of two years when income is falling. Treat that as typical behavior, not a rule.
- Student loans paid by someone else. Some guidelines allow exclusion with 12 months of documented on-time payments by the other party. Ask whether the lane follows that.
- Cash-out to pay off student loans. Fannie Mae’s student-loan cash-out option requires paying the debt in full from proceeds. Cash-out on jumbo lanes sits at lower leverage than purchase, with a cash cap on the largest lanes.
- High-balance conforming. A loan above the national baseline but under the county limit is conforming, not jumbo, and can use agency rules. Check the county first.
- Occupancy. The signed-offer path is for primary homes. Second-home leverage is lane-specific.
- A co-borrower. Adding one with steady W-2 pay can change the picture.
Federal Rules vs. Lender Rules
Keep the layers straight. Federal law requires every lender to make a good-faith determination that you can repay. It requires the lender to consider DTI or residual income. It doesn’t set a number. The old flat 43% cap was replaced by a price-based test in the CFPB General QM final rule. So 43% is not a federal jumbo rule. Any ceiling you meet on a jumbo file is the lender’s own overlay.
That’s also why two jumbo lenders can look at the same borrower and answer differently. It isn’t inconsistency. It’s the design.
Approved Is Not the Same as Comfortable
A file can clear a 50% ceiling and still be a stretch. If the contract income is untested, borrowing less than the maximum leaves room for an hours shortfall or a rescinded offer. Run your budget at the counted student-loan figure, not just the one you pay today, since repayment plans change.
Documentation Checklist
1. Executed offer or contract showing employer, role, pay and start date.
2. Two years of returns or transcripts if you are a contractor.
3. Most recent paystubs, if you have started.
4. Student-loan statements and the current plan letter.
5. Two months of statements on every asset account, with large deposits explained.
6. Written explanation of any gap or change in income.
Lenders re-verify employment before closing, so a changed start date or plan should be reported right away. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Frequently Asked Questions
Can a contract count as income on a jumbo loan?
Sometimes. Whether it counts depends on the lane. Lenders want an executed contract with clear pay and a start date, and many want a paystub or an employment check as well. Fixed base pay is easier than variable pay.
Are deferred student loans counted?
Usually yes. The lender may use the actual documented payment, an income-driven payment, or a balance-based figure. A documented zero payment under an income-driven plan is the main exception under Fannie Mae’s reference rules, and a jumbo lane may differ.
Do I need two years of returns as a contractor?
Two years is the general expectation, with exceptions for shorter history when a full 12 months of income is on the latest returns. Jumbo lanes may be stricter. Ask before you apply.
Does jumbo mean 20% down?
Not always. The headline lane reaches 90% leverage, while others stop at 80%. Occupancy, loan size and purpose change the leverage, subject to lender guidelines.
Can I buy before I start the job?
It’s possible on some files. A signed offer, fixed pay and a purchase of a primary home are the usual conditions in the agency reference rules. Some jumbo lanes want a paystub first.
