30 year mortgage loan rates explained for cautious first-timers

I'm a first-time buyer; yesterday at a coffee shop my lender pinged me that rates dipped a notch, and I finally paused to evaluate the offers instead of headlines.

Myth vs fact

• Myth: The lowest ad is the cheapest. Fact: APR vs interest rate can change total cost.
• Myth: All 30-year loans price the same. Fact: Credit score, points, and FHA vs conventional rates move quotes.
• Myth: You must lock immediately. Fact: Some lenders offer float-downs; I asked before paying points.

How I compare

1. Check best 30-year fixed rates lists, then verify with real loan estimates.
2. Use a mortgage points calculator to see breakeven.
3. Daily sanity-check refinance rates today in case plans shift.
4. Compare mortgage lenders on credits, lock length, and prepayment rules.

I'm leaning toward a no-points option now, but I'll revisit if pricing or my timeline moves.
