Out of curiousity why exactly an office. I mean I understand completely if you have a large number of employees and even then it may make more sense to just rent out some residential spot and work from there, unless you need the street address for something specific (legal issues, bank etc.)
I mean think about it for the cost of rent for office space, $2-$3K per month you can rent out some pretty hot residential space and have much more comfort. Hell you could rent out an entire house with a couple of stories
Just wondering is all.
