Question for Those Who Moved Cities

I'm hoping to re-locate to a new city/market next year. Young and want to explore a different part of the country. My key hesitation is whether this experience is worth the potential back-step in career progression. I have a strong network in my local market, know all the major players, typical deal terms, etc. like many of you.

For those of you who have moved cities mid-career, do you regret or recommend the experience relative to the impact it had on your career progression? Did you feel your career took a backwards step since you had to learn a new market, network a new Rolodex and prove yourself to a new group of people?

I work in development (office/resi) if that counts for anything. Thoughts much appreciated.
