How do we know whether to rent or buy? For those in IM or doing a Cardio/GI fellowship for 3 years, do you rent, or buy for 3 years? I did a 2yr research fellowship and bought. I ONLY did this because of 7 yrs in Mortgage Banking and Real Estate. Would I do this again? NOT if I didn't have the personal work experience in the industry. Those who entered residency or fellowship of < 4 years - we would love to hear your comments, and reasons.
