When cash-out refi makes sense
Paying off 18%+ APR debt with 7% mortgage rate: clear win on rate spread.
Funding a real home improvement that increases value (kitchen, bath): often pays for itself in appreciation.
Consolidating multiple high-rate debts when your current mortgage rate is similar to current rates: simplification + savings.
Bridging a major life event when no better option exists: defensible.
When to skip it
Current mortgage rate is 3–4% and current rates are 6–7%: you're re-rating $300k of debt to save on $50k of cash. Math fails.
Using cash for lifestyle (vacation, car, big-screen TV): you're paying 30 years of interest on a consumable.
Investing the cash in stocks: leveraged speculation, not investing.
When a HELOC keeps your first mortgage intact: cheaper, faster, less paperwork.
Cash-out refi vs HELOC
Cash-out: one loan, locked rate, 30-year term, but re-rates your entire balance.
HELOC: second loan, variable rate, 10-year draw + 20-year repay, but first mortgage stays put.
In a low-rate-first-mortgage environment (your 3% from 2021): always HELOC, almost never cash-out.
In a rising-rate environment where your old mortgage is similar to current rates: either works.
The closing-cost math
Closing costs are typically 2–5% of the new loan: $5–15k on a $300k cash-out.
Either rolled into the loan (paid via higher principal + interest) or paid out of pocket at close.
A larger closing-cost rollover is fine when borrowing for productive use. It's expensive when the cash is consumed.
Common cash-out refi mistakes
- Refi-ing out of a low rate just to access cash.
- Using HELOC-suitable amounts ($30k or less) via cash-out refi (high closing costs).
- Cashing out for lifestyle spending.
- Forgetting the tax-deductibility rules on use of cash.
- Ignoring the 30-year cost of the new monthly payment.
