Credit is the first pillar of qualifying for a Conventional Mortgage. While income and assets are equally important, your credit profile often determines not only whether you qualify, but also your interest rate, mortgage insurance costs, and overall loan pricing.
How Conventional Credit Scores Are Used
Mortgage lenders obtain a tri-merge credit report using Experian, Equifax, and TransUnion.
For an individual borrower, the lender uses the middle of the three mortgage FICO® scores.
Example:
- Experian: 735
- Equifax: 712
- TransUnion: 724
The qualifying score is 724.
For joint borrowers, each applicant receives a middle score, and the lender qualifies the loan using the lower middle score between the two borrowers.
What Credit Scores Are Acceptable?
Most Conventional loan programs require a minimum credit score of 620.
However, qualifying and receiving the best pricing are two different things.
Generally:
- 760 and above: Excellent pricing with little or no Loan Level Price Adjustments (LLPAs).
- 700–759: Very competitive rates and pricing for most borrowers.
- 620–699: Conventional financing is still available, but LLPAs and private mortgage insurance (PMI) costs may increase, especially with smaller down payments.
For many borrowers with credit scores below 700 and limited funds for a down payment, FHA financing may provide a more affordable overall monthly payment. However, borrowers with 20% or more down may still find Conventional financing to be the better long-term option because PMI may be avoided altogether.
One large and sometimes overlooked fact: if you have 40% down or 40% or more equity, LLPA or fico score adjustments to pricing and interest rates typically reduce or omit these adjustments or make them zero. So effectively someone for example with a 650 fico and 40% down, could acquire a similar rate to a 740 fico score borrower.
FICO Score and Impact on Your Mortgage Insurance Premium
The credit score being used for qualifying can be a determining factor for the percentage used to calculate mortgage insurance. An extremely high fico score has much less monthly mortgage insurance and as you slide down the grid, mortgage insurance monthly premiums increase. So effectively a lower fico score is a double-negative or double-impact because it impacts your interest rate + a higher mortgage insurance premium too.
Bankruptcy, Short Sale, and Foreclosure Waiting Periods
Conventional financing includes seasoning requirements after major credit events.
Typical waiting periods include:
- Chapter 7 Bankruptcy: Four years after discharge.
- Chapter 13 Bankruptcy: Two years from discharge, or four years from dismissal, subject to investor guidelines.
- Short Sale: Typically four years.
- Foreclosure: Generally seven years.
Certain extenuating circumstances may shorten these timeframes if supported by investor guidelines.
Disputed Accounts
Disputed accounts can delay underwriting.
If derogatory accounts remain in dispute, the lender may require the dispute to be resolved before final approval because disputed information can affect how mortgage credit scores are calculated. Your loan officer can determine whether removing a dispute is appropriate before applying.
Collections and Charge-Offs
Unlike some government loan programs, Conventional underwriting does not automatically require all collection accounts to be paid.
Charge-offs, typically I fight on these because the creditor has taken the tax break for charging it off as a loss, hence, I typically have success with not having to pay off charge-offs. Case-by-case though.
However, unpaid collections and charge-offs may negatively affect your credit score and overall loan pricing. Underwriters also evaluate the size, age, and overall credit profile when reviewing these accounts.
Mortgage Late Payments
Your mortgage payment history is one of the most important factors in Conventional Underwriting.
Recent mortgage late payments can significantly impact loan eligibility and pricing. Even borrowers with otherwise strong credit scores may encounter challenges if they have a pattern of recent housing payment delinquencies. No late payments in last 12 months and sometimes within the last 24 months. Mortgage late payments can be a big no-no when trying to obtain a new conventional mortgage, especially.
The Future of Mortgage Credit Scoring
For many years, Conventional loans have relied on classic FICO mortgage scoring models.
Beginning in 2026 and beyond, the mortgage industry continues preparing for the adoption of newer credit scoring models, including updated FICO models and VantageScore®, as directed by the Federal Housing Finance Agency. The transition is expected to provide lenders with additional tools for evaluating creditworthiness, although implementation timelines will vary among lenders and investors. This is currently but slowly being tested as of July 2026.
Try to Avoid These Mistakes
I would avoid taking out new accounts or credit from the time you apply. We will run a pre-closing soft credit report and anything you have taken, will get caught. Additionally, anything you did 60 days before applying, could also hit because the bureaus are that far behind at times.
Try to avoid paying off outside of escrow, if you are already under application and in-escrow. Also, try to avoid paying off and closing accounts. Best practice is to notify us and typically pay off all items thru closing at escrow.
Of course, continue to make all payments as normal, especially mortgage payments. If credit lates appear on the pre-closing credit report 48 hours from closing, this can cause a denial or extra hoops.
Avoid any unnecessary inquiries.
Please understand, these are just suggestions and helping you avoid a bunch of extra paper-work, extra hoops, or a possible denial.
Final Thoughts
Good credit opens the door to some of the most competitive financing available. While Conventional Loans are available to borrowers with credit scores as low as 620, stronger scores generally result in lower interest rates, reduced PMI costs, and fewer pricing adjustments.
Before applying, it’s wise to review your credit, reduce revolving debt when possible, and speak with an experienced mortgage professional who can help determine whether Conventional or another loan program best fits your financial goals in the Temecula Valley. I call this a Credit Consultation and is a part of Mortgage Planning.
