The first and most significant consideration has to be the location. Now, this is where your budget is important. Location and cost are linked to each other. If you decide to take up an office space in a prime locality with all amenities then your rate per square feet will be higher too. You may want to have an office space in Andheri, the heart of the city. But that could take a toll on your finances. What you do in such a case would be to take the second best option available. If office space in Andheri is out of budget, then check the other nearest area to set up your office. But if can adjust your finances, Andheri would still be the best choice.
