Today office space is a major concern and hence you should find proper place for renting the office space. When you think your business idea would not demand a commercial space to start the office then you could convert a room in your house as the office space. If you think you have enough space in the exterior of your house or in the backyard then you could construct a simple structure in which you could start an office for the projects that you win. If the projects could be completed with few people working continuously in your mini office and rest of them working remotely, then you could continue this style of managing projects with ease.
But, you should be confident enough to start this mini office for which you could take the loan on the house in which you are living in. You could pay the interest amount only until you get some projects, complete them and then get the big amounts paid by the clients for whom you have delivered the projects. Of course, the surplus amount after having paid for the effort and time each one has put in completing the projects could then be used for clearing the mortgage loan that you take on the house. For all the useful hints and tips you could always take the necessary help from North West mortgage advisor. Since the consultation would not charge you, you could have open discussion with them as many times as you want.
Just be cautious about the commitment that your friends show in completing the projects as not all of them nor you would have left your first job to do this additional work that gets you additional income. Once you get the money in huge after completing the project you could pay off the mortgage loan.
