This comes up constantly here, because so many people arrive for a position at the university, a hospital, or one of the corporate employers along the corridor.
The question is always some version of the same thing. I have accepted the job but I have not started it. Can I actually buy a house yet?
Usually yes. Here is how it works and what to watch.
Offer letter financing, in plain terms
Lenders qualify borrowers on income. When you have not started, there are no pay stubs, so the question is whether the lender will accept a signed offer or employment contract instead.
Many will. This is a recognized situation with established handling, not an exception you have to talk someone into. Relocating professionals do this routinely.
What they generally want to see is a signed offer or contract that states the position, the start date, and the compensation clearly, alongside all the ordinary documentation of your assets, credit, and existing obligations. Some programs also want to see reserves, meaning money in the bank sufficient to cover payments through the gap before your income actually begins.
The details vary by loan program and by lender, which is why the first move is a conversation rather than an assumption. The Consumer Financial Protection Bureau has neutral explanations of the mortgage process worth reading alongside whatever a lender tells you.
The question that determines your timeline
Ask one specific thing early: can I close before my first day, or do you need a pay stub first?
The answer changes everything about your planning.
If the lender can close before the start date, you can land with keys. Move in over a weekend, start work Monday, and skip temporary housing entirely.
If the lender needs a pay stub in hand, your closing moves to at least a few weeks after you start. That means a gap to cover, which means a short term rental or extended stay, a storage arrangement, and a family living out of suitcases during the same weeks you are trying to make a good first impression at a new job.
That gap is not a disaster and it is expensive and tiring. It is also entirely foreseeable, which means it is worth asking about before you are committed to a lender. Temporary housing in Greater Lafayette covers the options if you end up needing them.
What can complicate it
A few situations that need more attention.
Variable compensation. Bonus, commission, overtime, and incentive pay are generally treated more conservatively than base salary, often requiring a documented history you may not have in a new role. Build your budget on base pay and treat the rest as cushion rather than qualifying income.
Academic appointments with unusual structures. Nine month appointments, contracts with defined terms, and positions with research funding attached all get looked at more carefully. This is common enough here that local lenders see it regularly, which is one reason a local lender is worth using. The Purdue faculty and staff home buying guide covers this population specifically.
Medical residents and fellows, who often have low current income against a defined future and sometimes have access to loan products built around that. Worth asking about directly. Moving to Lafayette for a healthcare job covers the broader picture.
A contingent offer. If your employment is conditional on something not yet complete, a background check, a credential, or a visa, say so to your lender up front. Discovering it late is much worse than disclosing it early.
A start date that moves. This happens, and it can affect an approval built around the original date. Tell your lender immediately if it changes.
The other half: what you still owe elsewhere
If you have a home to sell, that is the real constraint, not the offer letter.
Your existing mortgage counts against you unless it is sold or unless you qualify carrying both. Some buyers can carry two. Many cannot, and then the sequencing becomes the whole project.
This is a two market move, and it deserves its own planning. Selling there and buying here covers coordinating two transactions in two markets, and should you sell before you buy works through the order of operations and what each choice costs you.
If you have equity in the current home and it is spoken for as your down payment here, that adds a timing dependency worth mapping explicitly on a calendar rather than holding in your head. What is my home worth covers how to pin down the number that money depends on.
The mistakes that undo an approval
This window, between approval and closing, is where I see otherwise smooth purchases come apart. Almost always for the same reasons.
Opening new credit. A card for the moving expenses, financing for furniture, a car loan because you need a second vehicle for the new commute. Any of these can change your qualification after the fact. Wait until after closing.
Large unexplained deposits. Money from family, proceeds from selling a vehicle, anything unusual landing in your account has to be documented. Not prohibited. Documented. Tell your lender in advance and it is a non event.
Changing the job. Renegotiating the offer, switching to a different role, moving from salaried to contract, or changing the start date all affect an approval built on the original letter.
Moving money between accounts right before closing, which creates a paper trail somebody now has to reconstruct.
The simple rule I give relocating buyers: from approval to keys, change nothing financial without asking first.
How this fits the timeline
The framework I use with every relocating buyer is the Relocation Runway, and financing sits at the very front of it deliberately.
Three to four months out, talk to a lender. Not to shop rates, though do that too. To find out what your situation actually supports and whether closing before your start date is possible. That single answer shapes every other decision.
Two to three months out, narrow neighborhoods. The neighborhoods guide is where that starts.
Six to eight weeks out, tour, in person or by video.
Four to six weeks out, go under contract, timed so the closing lands where your financing allows.
The people who feel calm gave themselves a runway. The ones who call me three weeks before a start date can still be helped, and they have fewer options and a much worse month.
Use a local lender
I say this to every relocating buyer and I will say it here.
A national call center can absolutely write your loan. What they generally cannot do is answer the phone when a listing agent calls to ask whether your financing is real, and that call happens more often than buyers realize when a seller is comparing offers.
Local lenders here also see academic appointments, hospital contracts, and relocation situations constantly, which means fewer surprises in underwriting. Pre-approval versus pre-qualification explains why the strength of your letter costs or wins you houses.
The short answer
You can very likely buy before you start. Ask a lender early, get the specific answer about closing before your first day, and build your timeline backward from it.
Then change nothing financial until you have the keys.
If you have an offer letter in hand and want help mapping a realistic timeline for this market, that is a conversation I have most weeks. Grab a time on my calendar. A real person reads every message, and there is no pressure either way. Let's get you home.
