One final answer
"Is it better to rent or buy a home right now?"
Buying builds equity over time. Despite high rates, you're paying yourself — not a landlord.
At 7% mortgage rates, renting is often cheaper monthly. Flexibility outweighs equity gains right now.
ChatGPT assumes long-term stability; Claude prioritises short-term flexibility. Both ignore local market variance.
US avg mortgage rate: 6.8% (Mar 2025). Price-to-rent ratio in top 20 cities averages 24 — renting typically favours below 15.
