Utah Due Diligence Deadlines Without the Drama

If your Utah buyer says "we're past due diligence," you should know exactly what that means before you nod along. The Utah contract does not run on handshakes and vibes. It runs on written deadlines you both agree to.

For FSBO sellers, that is good news. Written deadlines keep everyone honest. You just have to read them, track them, and enforce them the right way.

What due diligence actually is in the Utah REPC

The Utah Real Estate Purchase Contract, or REPC, is the state-approved form that most residential deals use. You can read the blank form directly from the Division of Real Estate in the official REPC PDF.

Due diligence is your buyer’s window to investigate the property and decide if they want to proceed. Inspections, HOA docs, insurance quotes, second walk-throughs with a contractor for that kitchen they swear they will not gut. It all fits here.

Two things matter for you as the seller:

1. The due diligence deadline is negotiated. You fill it in. There is no magic statewide default of 10 days or 15 days. It is whatever you and the buyer write into the applicable deadline field of the REPC.
2. What happens when the deadline passes depends on the exact contract version and any addenda. Read the signed language before assuming silence means satisfaction, cancellation, or waiver.

Financing, appraisal, and settlement are separate clocks

Buyers like to lump everything into "due diligence." Do not. The REPC treats these as distinct contingencies with their own lines.

• Due diligence deadline: For inspections and general investigation. The buyer may investigate, cancel, or propose a written resolution as the signed contract allows. A repair or credit request is a negotiation, not an automatic seller obligation.
• Financing and appraisal deadline: For loan approval and, if applicable, the home appraising for enough to make the lender happy. This is not automatic. The buyer must meet the requirements spelled out in the financing section.
• Settlement deadline: The target date for signing and funding. That date is also negotiated, and it is not the same as getting keys. Possession is a separate line item.

Why keep them separate? Because a buyer can be done with inspections but still have a financing condition pending, or vice versa. You need to know which condition they are trying to cancel or resolve. A vague text that says "we need more time on everything" is not a notice under the REPC.

And yes, inspections deserve their own plan. The federal guide to scheduling a home inspection on the Consumer Financial Protection Bureau site is a useful neutral explainer to share with buyers so they do not wait until hour 23 to book someone.

Written notices and amendments are not optional

Treat every deadline notice and change as a document problem. Use the signed contract’s notice and amendment provisions rather than relying on a call or text.

Standard practice in the REPC:

• Notices must be in writing and delivered to the other party or their agent, if they have one. Check the notice provisions in your signed version for the exact delivery rules. Email counts only if that version allows it.
• A request for repairs or a seller credit after inspections is typically handled by a Due Diligence Condition resolution form or an Addendum. A text thread is not an addendum.
• Any change to a deadline must be done by a signed Addendum. Both sides must sign. A one-sided "we are extending ourselves" note does not extend anything.
• Keep earnest money rules in mind when you discuss extensions. Your earnest money handling should match what you wrote: Utah FSBO Earnest Money: Where It Goes.

For negotiation tone after inspections, sellers often do better with a short, clear response form instead of debating each item on the phone: How Utah FSBO Sellers Handle Inspection Requests.

Deadlines FSBO sellers mess up, and how not to

Three spots cause most drama:

1. Assuming weekends do not count. The REPC counts calendar days unless your version says otherwise. A 7-day deadline that starts on Monday ends Sunday. Track it that way.
2. Accepting late resolutions. If buyer misses their due diligence deadline and then sends a big repair list, you are not automatically required to negotiate. You have options under the contract, but you must act in writing and on time.
3. Mixing up financing issues with appraisal issues. A buyer who is denied financing is different from a buyer whose appraisal came in low. The low appraisal path has its own options, credits, and termination rights. More here: Low Appraisal on a Utah FSBO? Your Real Options.

A simple deadline calendar you can actually use

Do not invent dates. Copy the dates from your signed REPC and Addenda, then work backward for prep.

Build this table the day you go under contract:

Checklist to run every morning until you close:

• What deadline hits next, and what writing is required?
• Has the writing been received in the way the contract says it must be delivered?
• Do we need an Addendum to change a date, and is earnest money affected?
• Has title been ordered and are HOA docs in process? Your title company timeline matters: Choosing a Title Company for a Utah FSBO Sale.
• Is our Utah FSBO guide binder up to date with every signed page?

Take your signed REPC, pull every filled deadline into one calendar, add two reminders for each, one day before and day of, and require everything in writing. You will avoid most of the late-night drama sellers complain about.
