My dad knows quite a few podiatrists in LA suburbs, Beverly Hills, etc. that live in multi million dollar homes. Now most are in the $1-2.5 million dollar range which is only about a 2500-4000 square foot home. I am sure others live in larger houses, such as Ali Sadrieh, he has a very successful practice in BH, but I havn't seen his house, so I cannot attest. Just think about what makes you happy. The podiatrist will give you a very nice lifestyle some people would only dream of, and you can make it as profitable as you like by the work and planning you put into your practice.
