Need advice with Buy or Rent

[Mugu Radu]

Hello everyone, I'm new here and really want to learn about the real estate world.

We are thinking to sell our house because our son will go to a specific high school next year that charges 12k per year if you don't live in their zip code. We hope to have 100k cash from the sale after all agent fees and everything paid off. We will only live in this area for 4 years and after our son finishes high school our dream is to but land and build a custom home.

Do you think it's a good to rent for 4 years and invest the 100k in real estate? or buy a house in this area (property taxes and house prices are insane) and sell it after 4 years?

What would you do?

We never owned a rental property but would love to start and learn.

Thank you so much for your help God bless you.
