Rofo is a real estate portal focused entirely on those looking to rent, sell, or buy, commercial space in the US. Those looking for a new office can search for one that meets their requirements and also read reviews which are written by others who currently share the same building. If you can’t find a space that suits your unique needs, you can also post exactly what you are looking for anonymously and have others find you. The “Rofometer” allows anyone to enter the current rent they are paying and the specifics of their space and then compare the price with that of similar properties in the area. So, if you specifically need to find or rent out a commercial space, Rofo is a good place to start.
