Average 30-Year Mortgage Rate in the US…
Why it spread
This post spread because it landed on a hot topic that week and came from an independent author, reaching 58,566 views with 411 likes, 74 reposts, 10 quotes, and 82 saves.
What worked
- The post frames a long run of decades in one compact list, moving from the 1970s at 8.9% down to the 2010s at 4.1% and back up to the 2020s at 5.4%, which makes a slow story instantly readable.
- It anchors the list with memorable extremes: the all time low of 2.65% in January 2021, the 2023 peak of 7.79% in October 2023, and today's rate of 7.40% as the highest since November 2023.
- It pairs a hot topic with an independent author, and the measured response shows strong saving and sharing relative to quoting, with 82 saves and 74 reposts against only 10 quotes.
What to borrow
We could take one long running series of our own, summarize it as a short list of periods with a clear high, low, and current value, and let the contrast between the extremes carry the post.
Careful
Do not over read the quote rate, which is below average, or treat the reach as proofaland, since the source reach is only in the top quarter and the account's typical performance is not given.
