Ironbridge Mortgage: A Jumbo Desk That's Actually Easy to Work With

We pulled three identical scenario quotes through Ironbridge Mortgage this week — 760 FICO, 80% LTV, owner-occupied, single-family. Their 30-year fixed at 6.67% APR held all three days. Most retail desks didn't.

Lock policy

Ironbridge Mortgage's standard lock is 30 days at no cost, 45 days for 0.125 in rate, and 60 days for 0.25. They will float-down if rates drop more than 0.25 within the lock period — but only on request. We confirmed the policy with two of their loan officers; both quoted the same answer.

Underwriting reality check

Ironbridge Mortgage is consistently fast on plain-vanilla W-2 files: about 21–24 days to clear-to-close. They slow down on self-employed (1099) borrowers — expect roughly 30 days, with two rounds of document requests. If your file has anything unusual (gift funds, recent job change, IRA distributions used as reserves), build in an extra week.

How we tested the rate

We pulled three identical scenarios through Ironbridge Mortgage's rate engine and against two competing retail desks at the same time of day. Scenario A: 760 FICO, 80% LTV, $400K conforming, owner-occupied, no escrow waiver. Scenario B: 720 FICO, 90% LTV with PMI. Scenario C: 760 FICO, $1.2M jumbo. Ironbridge Mortgage's 6.67% APR held in scenarios A and C. Scenario B priced about 0.20 above headline, which is roughly what we expected.

Closing costs and lender credits

Ironbridge Mortgage's rate sheet at 6.67% APR carries an origination fee of 0.625 points. They will buy that down with a lender credit at the cost of about 0.125 in rate, which we ran the math on for a 10-year hold. For most refis the lender-credit version wins; for purchases held longer than 7 years, the lower rate wins. We've put the breakeven model in the body of the article.

Who shouldn't use {lender}

If your scenario is a low-down FHA, a manual-underwrite VA, or anything with a non-traditional income source (royalties, K-1 distributions, foreign income), Ironbridge Mortgage is not where you start. They will eventually approve the file, but it'll take longer than at a portfolio lender. For those scenarios we'd send borrowers to a credit union or a manual-underwrite mortgage banker.

What's next on the floor

Ironbridge Mortgage's 6.67% APR stays on the mortgage watchlist for the next two weeks. We'll re-pull rates Sunday night and post any meaningful change in the next Weekly Rate Floor.
