From 7.2% to 6.4%: Sarah's 90-Day Refinance Journey

Sarah looking at mortgage documents with a calendar showing 90 days

Sarah called me in March 2026, frustrated and tired. Her adjustable-rate mortgage had just reset from 4.2% to 7.2%. Her monthly payment jumped from $1,450 to $2,100 overnight. She was a single mom, a nurse, and she was scared.

“I can't afford this,” she said. “I thought ARMs were supposed to be cheaper.”

They are—for the first five years. Then they can become nightmares.

I told her we had options. But she needed patience. Refinancing isn't a one‑day event. It's a process. Here's how we turned her 7.2% nightmare into a 6.4% solution—and saved her about $230 a month.

Week 1: The Assessment

First, I pulled her credit report. Score: 680. Not terrible, but not great. Her debt‑to‑income ratio was 45% because of the new higher payment. We needed to fix that.

Her home was worth about $480,000. She owed $310,000. LTV was around 65%. Good. She had equity. That gave us options.

I asked her to gather pay stubs, tax returns, and bank statements. She groaned. “That's so much paperwork.”

“I know,” I said. “But every loan officer will ask for the same stuff. Let's get it done once.”

Week 2: Shopping for Lenders

I gave Sarah a list of three lenders: her current bank, a credit union, and an online lender. I told her not to mention the other offers until she had all three in writing.

Her current bank offered 6.7% with $6,000 in closing costs. The credit union offered 6.5% with $4,000 in costs. The online lender offered 6.4% with $5,000 in costs.

She was leaning toward the credit union. I said, “Call the online lender and tell them you have a better offer.”

She did. They dropped their rate to 6.3% and reduced closing costs to $4,500. Now she had two strong offers.

“This is exhausting,” she said. “But I see why it's worth it.”

Week 3: Locking the Rate

Rates were volatile in April 2026. The Fed was signaling no cuts. Middle East tensions were keeping oil prices high. I told Sarah to lock her rate for 60 days. She locked at 6.4% with the credit union.

Two weeks later, rates jumped to 6.7%. She texted me: “Thank you for making me lock.”

I don't have a crystal ball. But I know that waiting for a lower rate is a gamble. Locking gives you certainty.

Week 4-8: The Underwriting Wait

This is the part nobody talks about. Underwriting took forever. The loan officer asked for extra documents twice. Once for an explanation of a $500 deposit from her mom. Once for a letter about her student loan deferment.

Sarah was annoyed. “Why do they need all this?”

“Because they're lending you $310,000,” I said. “They want to be sure you can pay it back.”

She stuck with it. Every time they asked for something, she sent it within 24 hours.

Week 9: The Appraisal

The credit union ordered an appraisal. The appraiser valued her home at $485,000—$5,000 more than her estimate. Her LTV dropped to 64%. That meant no PMI. Another win.

Appraisals can be nerve‑wracking, but Sarah's home was in good shape. She'd updated the kitchen and bathroom. It paid off.

Week 10-12: The Final Hurdles

Two weeks before closing, the credit union discovered a $200 collection from an old medical bill. Sarah had paid it, but it still showed as outstanding. We sent proof of payment. They cleared it.

Then her employer changed payroll systems. Her pay stubs didn't match the previous format. The underwriter asked for a letter from HR. Sarah got it in one day.

Finally, on June 5, 2026, she signed the closing papers. Her new rate: 6.4%. Her new payment: $1,870 (excluding escrow). That's $230 less than her ARM‑reset payment of $2,100. Over 30 years, that's $82,800 in savings—minus closing costs of $4,000, net savings of nearly $79,000.

She cried when she signed. “I didn't think I could do it,” she said.

But she did. She followed the process, stayed patient, and won.

What You Can Learn from Sarah

If you're facing an ARM reset, don't panic. You have options. But you need to start early—at least 90 days before your rate adjusts. Here's your checklist:

  • Check your credit score. Improve it if you can.
  • Shop at least three lenders.
  • Lock your rate when you see a good number.
  • Gather documents before you apply.
  • Respond to underwriters quickly.

I will keep posting updates on this. Check back soon.

P.S. Sarah sent me a photo of her first new payment confirmation. She wrote, “Best $4,000 I ever spent.” That's the right attitude.
