Mortgage Loan Defects Rise as Refinancing Picks Back Up

The mortgage industry’s critical defect rate jumped to 1.71% in the first quarter, up from 1.38% the quarter before, as a surge in refinancing activity strained lenders’ compliance processes.

Why it matters: A critical defect means a loan wouldn’t qualify for insurance or sale — the kind of problem that can cause delays, repurchase demands, or last-minute complications for a borrower who thought they were nearly done.

By the numbers

• The critical defect rate rose 23.9% quarter-over-quarter, from 1.38% to 1.71%, and is up 30.5% from a year earlier, when it was 1.31% in Q1 2025.

• Legal, regulatory, and compliance defects made up 26.02% of all defects — the highest share since Q1 2021, and the leading defect category for a second straight quarter.

• Refinance loans made up 32.05% of reviews, up from 27.37% the prior quarter — the highest since Q1 2022 — and refinance-specific defects rose to 38.57% of all defects.

• Asset defects improved the most, falling from 15.25% to 10.41%.

State of play: ACES Quality Management, which tracks the data through its industry benchmarking software, said the swing followed mortgage rates briefly dipping below 6% in February, which triggered a fast jump in refinance volume — and, with it, more eligibility and compliance work for lenders to get right on tighter timelines.

Zoom in: Loan type mattered too. VA loans saw the biggest improvement, with their defect share falling from 12.32% to 9.78%. FHA loans stayed roughly flat at 32.27% of defects, still well above FHA’s 24.46% share of all reviews — meaning FHA loans are flagged for critical defects disproportionately often relative to how common they are.

What this means for you: None of this means your loan is doomed, but it’s a reminder that a fast-moving rate environment can add friction to the process — especially if you’re refinancing. Extra time for underwriting or more documentation requests aren’t necessarily red flags; they can be lenders working through exactly this kind of compliance pressure. Keeping your own paperwork organized and responding quickly to requests is one of the few things you can control. Copiafy’s document tracker can help you keep income, asset, and closing paperwork in one place so you’re not scrambling if your lender asks for something twice.

Bottom line: Loan quality isn’t falling apart — but the refinance rebound is testing lenders’ ability to keep pace, and borrowers should expect a bit more scrutiny along the way.
