OB is plenty affordable if you are willing to live small and throw away most of your junk. There is a 1-bed condo on Cape May 2 blocks from the ocean for sale for $300,000. You even get a pool and a parking spot!
Actually you don’t need to get rid of all your junk. My dorm room in school was 110 square feet. I did not feel especially crowded. The condo on Cape May is 640 sq ft.
