My classmate is a real estate agent. I said I wanted to buy a house from her for a year or two. What if I regret it?

My classmate is a real estate agent. She said she wanted to buy a house from her for a year or two, and she regretted this treatment: in fact, there is no need to be upset because she is a classmate. Buying a house depends on her own economic strength and opportunities. You can refuse to buy a house on the grounds that money is inconvenient or the real estate market is unstable. After all, buying a house is a big deal, and you have to make a decision.
