I want to ask something. People always ask me why I rent and "waste money" instead of getting a mortgage etc.

I explain to them that I put most of the money I make into my company, and have a greater ROI than if I put the money into real estate. But, since I have to live somewhere, I rent.

Yet, I am not sure this argument is correct. If I had money for a down payment, perhaps the strategy of getting a mortgage would win in the long run. So, instead of getting into the details, I usually mention I also like to be able to change apartments every year or so.

What are your thoughts - those of you who have now, or have had, growing startups?
