📉 Mortgage Pre-Approval Denied? The Hidden Reasons Loans Collapse Before Closing 🔍

Why Pre-Approvals Fall Apart

A mortgage pre-approval is not a guarantee.

It’s a conditional financial snapshot — and if that snapshot changes, the loan can fall apart fast.

As a mortgage broker at Medallion Funds, I’ve seen strong buyers lose homes days before closing because something changed between pre-approval and underwriting.

If you're buying in Texas — especially competitive markets like Houston, Katy, Fulshear, or Dallas — understanding why pre-approvals fail could protect your deal.

Let’s break it down.

What a Mortgage Pre-Approval Really Means

A mortgage pre-approval is based on:

·Credit report

·Income documentation

·Asset verification

·Debt-to-income ratio (DTI)

·Preliminary underwriting guidelines

It is not the final underwriting decision.

Final approval happens after:

·Full underwriting review

·Appraisal

·Title work

·Employment verification

·Updated credit pull

That’s where deals often fall apart.

The 7 Most Common Reasons Pre-Approvals Collapse

1️⃣ Income Changes

·Job switch

·Commission drop

·Overtime reduced

·Self-employed income volatility

Underwriters require stable, verifiable income. A new job or compensation structure can trigger requalification.

2️⃣ New Debt Before Closing

Buying a car.
Opening a credit card.
Financing furniture.

Even small new debt can push your debt-to-income ratio over program limits.

This is one of the most common mortgage approval mistakes.

3️⃣ Credit Score Drops

Missed payment
Higher credit utilization
Co-signed loan reported

A 20–30 point drop can:

·Increase your rate

·Change your loan program

·Kill approval entirely

Lenders run a final credit check before closing.

4️⃣ Appraisal Issues

If the appraisal comes in low:

·Loan-to-value (LTV) increases

·Buyer must bring more cash

·Seller must reduce price

·Deal dies

Pre-approval does not protect against appraisal risk.

5️⃣ Asset Verification Problems

Large undocumented deposits
Gift funds not sourced properly
Insufficient reserves

Underwriters must paper-trail every dollar.

6️⃣ Self-Employed Documentation Gaps

For business owners and 1099 earners:

·Tax returns matter more than revenue

·Write-offs reduce qualifying income

·Year-over-year declines can disqualify

Pre-qualification without reviewing full returns is dangerous.

7️⃣ Rate Lock & Market Volatility

If rates spike before you lock:

·Payment increases

·DTI increases

·You may no longer qualify

In volatile markets, structure matters.

Why Big Bank Pre-Approvals Fail More Often

Many retail banks issue automated approvals without:

·Deep income review

·Full asset documentation

·Exit strategy discussion

·Program flexibility

As a broker, we:

·Run files through multiple lenders

·Stress test DTI

·Review tax returns upfront

·Identify risk early

That’s how you protect closings.

Texas-Specific Risk Factors

In Texas markets like Houston and Katy:

·Property taxes are high

·Insurance premiums fluctuate

·HOA dues can impact DTI

·Flood zone designations affect approval

All of these variables must be accounted for at pre-approval.

If they aren’t, the deal can collapse during underwriting.

How to Make Sure Your Pre-Approval Doesn’t Fall Apart

Here’s the discipline checklist:

✅ Do not open new credit
✅ Do not change jobs without consulting your lender
✅ Keep credit utilization low
✅ Don’t move large sums of money
✅ Lock your rate strategically
✅ Use a broker who underwrites upfront

Pre-approval should be a risk management process — not a sales document.

Final Take

Most pre-approvals fall apart because they weren’t structured properly from day one.

If you're buying in Texas in 2026, you need more than a pre-approval letter.

You need:

·Real underwriting analysis

·Exit flexibility

·Conservative qualification

·Strategic rate lock timing

If you want a pre-approval that actually closes, that’s what we build at Medallion Funds.
