It depends almost entirely on what kind of change it is. A lateral salaried move in the same industry usually survives underwriting with a new offer letter and a paystub, while going from W-2 to 1099 or self-employment usually ends that loan as structured, and everything else falls somewhere in between.
Why lenders re-verify employment right before you close
Your approval is not a snapshot. It is a condition that has to still be true on the day you sign.
For salaried and hourly borrowers, lenders complete a verbal verification of employment, commonly within 10 business days of the note date. Someone calls your HR department or checks a third-party employment database and confirms you are still employed in the position on your application. Self-employed borrowers get a business existence check instead, typically within 120 days of closing.
This is the step that catches job changes, and it catches them at the worst possible moment. I have had one surface on closing day itself. The verification call came back showing the buyer had already quit, with a new position still months away from starting, and nobody had mentioned it to us. That contract was cancelled and the house was lost. I go through that file in more detail in Can You Be Denied After Clear to Close?
By the time a verification call turns up a change, the appraisal is paid for, the movers are booked, and the seller is expecting to hand over keys. Every fix that might have worked needed to happen weeks earlier.
Nothing about the change itself is dishonest. The problem is purely one of timing. Underwriting has to re-approve income it already approved, using new facts, with days left on the clock. That is a bad position to be in, and it is entirely avoidable by saying something early.
Same-industry salaried moves: usually survivable
This is the best-case version, and it is common along the Front Range aerospace corridor. Engineers move between Lockheed Martin in Littleton, Ball in Broomfield, ULA in Centennial, and Sierra Space in Louisville constantly, usually for a raise, usually with the same job function.
Underwriting can generally handle it. Your income type has not changed, your field has not changed, and your history in the industry carries forward. The lender will want a non-contingent offer letter or employment agreement showing your base salary and start date, a start date that works with the closing timeline, and in most cases one paystub covering a full pay period at the new employer.
The friction is schedule, not eligibility. If your first paystub does not exist until three weeks after your scheduled closing, the loan waits for the paystub even though the income is fine. Some lenders will close on a non-contingent offer letter alone when reserves are strong. Many will not, and that decision belongs to the specific investor buying the loan.
Tell your loan officer the day you accept. With two weeks of notice this is a paperwork item. With two days of notice it is a closing delay.
Moving from salaried to commission or bonus-heavy pay: much harder
This one catches people off guard, because the new job usually pays more.
Underwriting cannot use income it cannot document a history for. Commission and bonus income generally require a two-year track record to average, and some products allow 12 months with strong compensating factors. A brand new commission plan has zero months of history no matter how credible the projection is. So the underwriter uses your base salary only and ignores the variable portion entirely.
If your base at the new job is lower than your old salary, your qualifying income just dropped, sometimes dramatically. A move from $110,000 salaried to $84,000 base plus projected commission looks like a promotion on paper and looks like a $26,000 pay cut to underwriting.
I always tell clients to look at the base number and nothing else when they are mid-transaction. That is the only figure the file can use. Denver tech and medical device sales roles are especially prone to this, since aggressive commission structures with modest bases are the norm.
Once the loan closes, the new structure is your business. Before it closes, only the guaranteed portion counts.
Going from W-2 to 1099 or self-employment: usually fatal to that loan
If you leave a W-2 job to become a contractor, a consultant, or the owner of your own LLC, the loan as structured is almost certainly finished.
The reason is structural. Self-employed income is calculated from filed tax returns, and standard guidelines generally require two years of self-employment history. Some files qualify on one year of returns with strong compensating factors. Nobody qualifies on a business that started last month, because the documents that establish the income do not exist yet.
This is a real Front Range pattern. Trades workers who have been W-2 employees for a general contractor decide to form their own LLC and take work directly. Nurses at UCHealth or HealthONE move to travel contracts through an agency. Engineers go independent as consultants at a much higher hourly rate. Every one of those people is making a good financial decision and a terrible mortgage-timing decision.
The workable options are narrow: delay your start date until after closing, delay the closing until you have the tax history (which usually means a new contract and a new pre-approval), or restructure the loan around a co-borrower’s W-2 income. Non-QM and bank statement programs exist for self-employed borrowers, but they still want roughly two years of business history, so they are the answer for year three and not for week two.
Promotions and internal transfers
A promotion with the same employer is normally the easiest case, and it usually requires only a letter from HR or a new paystub confirming the new title and pay.
The thing to watch is not the title. It is the compensation structure. A promotion from staff nurse to unit manager at a hospital in Aurora is a clean salary-to-salary change and nobody blinks. A promotion from account manager to regional sales director that swaps $30,000 of salary for a variable bonus pool is a much bigger underwriting event than the word “promotion” suggests.
Internal transfers to a new city add a second layer. If your employer moves you from Denver to Dallas while you are buying a house here, the underwriter now has a question about whether you will occupy the property, and occupancy drives the entire loan structure. That has to get addressed directly rather than glossed over.
The rule I use: if the paystub will look different in kind and not just in amount, treat it as a job change and disclose it as one. If only the number moved, it is a document request.
Gaps between jobs
A gap is its own condition, separate from the new job.
Underwriters generally want an explanation for any employment gap over 30 days in your recent history, and a longer gap raises the bar. After an extended absence from the workforce, six months or more, many programs want to see you established in the new position, often six months of receipts, before the income counts as stable.
A one-week break between a Friday resignation and a Monday start is a non-event. Six weeks off between contracts is a letter of explanation. Nine months out of the workforce followed by a brand new job is a stability problem that documentation alone does not solve.
Timing matters more than most people expect. The gap does not have to be long to be inconvenient. If your last paystub from the old employer is in March, your first from the new employer is in May, and you are closing in April, there is a stretch where no lender can verify current employment income at all. That is a hard stop, not a paperwork delay.
Probationary periods and contingent offers
Read your offer letter before you assume the income is usable.
Two clauses cause trouble. A probationary period means your employment is explicitly not settled, and underwriters can require you to complete it before the income is considered stable. Contingencies mean the offer is not final. Offers subject to a background check, a drug screen, a licensing requirement, or a security clearance are conditional until those clear, and lenders that accept offer letters generally require them to be non-contingent.
The clearance issue is specific to this market. Between the aerospace primes, the defense contractors, and the federal workforce at the Denver Federal Center in Lakewood, plenty of Denver job offers hinge on a clearance transfer that can take months. An offer letter with a start date “pending clearance adjudication” is not something an underwriter can build a file on.
If your new role has a probationary period or an open contingency, say so before anyone assumes the letter is clean. It is much easier to plan around a known condition than to discover it during a final review.
What documentation a new position requires
Expect to produce most or all of the following, and expect the requests to come fast:
- A signed, non-contingent offer letter or employment agreement showing title, base pay, pay frequency, and start date
- At least one paystub covering a full pay period, in many cases
- A written or verbal verification of employment from the new employer
- A letter of explanation covering the change and any gap
- An updated loan application reflecting the new employer
- For commission or bonus pay, documentation of history, which is usually where the file breaks
Two practical notes. HR responsiveness is a real variable, and a new employer’s HR department that takes four days to return a verification call can push a closing by itself. And your old employer still matters, because the underwriter will want the transition documented on both ends.
A worked example of how the math breaks
An illustrative composite, using round numbers.
A buyer is under contract at $675,000 in Central Park, approved at $10,500 a month in qualifying salary. Total monthly obligations including the new housing payment come to $4,410, which puts the debt-to-income ratio at 42 percent. The file is approved and clean.
Eleven days before closing, they accept a better job. New pay is $7,600 a month base plus a projected $45,000 in annual commission, roughly $11,350 a month all in.
Underwriting cannot use the commission, because there is no history. Qualifying income becomes $7,600. The same $4,410 in obligations now produces a debt-to-income ratio of 58 percent. That is outside guidelines, and the loan cannot close as structured.
To get back under 45 percent, they would need about $9,800 in usable monthly income or roughly $990 less in monthly obligations, which means a substantially smaller loan and a house that is no longer the one under contract.
The fix in that situation was simple and had nothing to do with the mortgage. The buyer asked the new employer to move the start date two weeks, closed on the old job, and began the new one the following Monday. Same job, same raise, house intact.
Should you tell your lender? Yes, always
Tell them the day you accept, before you resign if possible.
Hiding it does not work, and it makes everything worse. The verbal verification will surface it. The paystub request will surface it. Tax transcripts will surface it later. When it comes out days before closing instead of weeks, you have removed every option that might have saved the deal, including the one that usually works, which is adjusting your start date.
There is also a signature problem. You sign an application attesting that the information is accurate, and you sign again at closing. Knowingly closing a loan on employment you no longer hold is not a gray area, and it is not worth it for any house.
I have never once seen early disclosure make a file worse. I have repeatedly seen late disclosure cost people their earnest money. The conversation you are dreading is a fifteen-minute call that usually ends with a plan.
If the change is unavoidable, here is the play
Sometimes the offer will not wait and you have to move. Work the problem in this order.
Negotiate the start date first. Pushing it past your closing date solves more of these than any other single move, and most employers will accommodate a two-week shift for someone buying a house. Second, get the offer letter in front of your loan officer immediately so the base pay and any contingencies can be evaluated against your actual ratios. Third, ask about a closing extension, since a one to two week extension is a normal request in a Denver contract and far cheaper than a failed closing. Fourth, look at restructuring, whether that is a larger down payment, a co-borrower, or a different program. Last, if the loan genuinely cannot survive, find out what the earnest money exposure is before you resign rather than after.
The worst version of this is a borrower who makes the change quietly, hopes it goes unnoticed, and finds out three days before closing that it did not.

Frequently asked questions about changing jobs before closing
How long do I have to be at my job before I can get a mortgage?
There is no rule requiring two years with the same employer. Lenders look for a two-year history of employment overall, and moves within the same line of work are normal and expected. What matters is whether the income is stable and documentable. Salaried pay is the easiest to verify, while commission, bonus, and self-employment income usually require a longer track record. Certain conventional loans even allow closing before your first day under strict conditions.
What happens if I get laid off before closing?
The loan will not close. Lenders re-verify employment within a few days of the closing date, and if you are no longer working there, the income used to approve you no longer exists. Severance rarely replaces it. Call your loan officer the day you find out, because staying quiet about it is a serious problem rather than a technicality. Depending on timing, you may be able to pause, add a co-borrower, or exit under your loan contingency.
I just got a raise. Does that help or hurt my mortgage approval?
A raise in base salary almost always helps and is simple to document with a new pay stub or a written verification of employment. Risk enters through how the raise is delivered. Trading a higher base for commission, bonus, or profit sharing can lower your qualifying income even when your total pay rises, since variable compensation generally needs a one to two year history before it counts. Tell your lender before the change takes effect.
Can I use income from a second job or a side gig to qualify?
Sometimes, but it usually takes a two-year history of that secondary income plus evidence it is likely to continue. Part-time, overtime, and bonus income is typically averaged over 24 months, and some programs allow a 12-month average with strong justification. A side business you started six months ago will generally not count. Gig and 1099 work is treated as self-employment, which carries its own tax-return documentation requirements.
Can I close on a house while I am still in a probationary period at a new job?
Usually yes. A standard probationary period is not an automatic denial, particularly when you moved within the same field and your pay structure did not change. The real obstacle is a contingent offer, meaning employment that still depends on a background check, a license, a drug screen, or a start date that has not arrived yet. Lender requirements vary here, so confirm before you write an offer.
The best job of your life can still kill your loan. Underwriting is not grading your career, it is grading whether your income looks the same on closing day as it did on the application. Call me before you sign the offer letter, not after you have given notice. Only one of those two conversations has options in it.
