Just looked back at how mortgage rates were sitting around October 2023 and honestly it's wild how much has shifted since then. Back then, 30-year mortgages were hovering around 8.26% while 15-year fixed rates were at 7.33%. People were paying like $752 monthly on a $100k mortgage with those rates. The APR on 30-year loans was running 8.20% at that time, which felt pretty high for borrowers trying to lock in. What struck me was how jumbo mortgages weren't that much lower - they were at 8.12% - so the spread wasn't huge. Refinancing made sense for some folks if their existing rate was lower, but the math had to work out. The whole thing came down to credit scores, down payments, and debt-to-income ratios. FHA loans needed just 3.5% down if you had decent credit, while VA and USDA programs were options for specific groups. Comparing lenders back then was key because conventional mortgages, government-backed programs, and jumbo options all had different terms. Rate locks were typically 30-60 days, sometimes extendable to 90-120 days depending on the lender. Interesting to see how the october 2023 mortgage rates landscape compared to where things are now after all the Fed moves and inflation shifts that followed.
