And if the question is about renting your own space, I look for the following.
Price- let’s face it, overhead is the biggest factor in being able to run a profitable business.
Size- How much space do I need now? and how much in the near future is also important.
Location- I could have the best gym in the world, but if it is hard to get to, no one will come there.
Parking- Does the space have adequate parking for the number of clients I will have in the space at any one time.
Exposure- Will the space do some advertising for me? Can people driving by see my signage? (Kind of goes with location, but is a little bit of it’s own category too.)
All of these make a difference. And I can sometime work around a few with a little effort. I listed them in the order of most to least important to me. But one can totally affect the decision pro or con. Like if there is no parking in reality. If the lot is full all day from other businesses traffic it is good for exposure, but bad for clients. So, I attempt to get some dedicated parking spots for my business. I won’t rent without them in that situation.
