There are so many 'For Rent' signs everywhere. None of them are clear about what builidng is for rent or how much they are asking and most of the units are already rented when you do manage to contact the correct person. My best guess is that the signs are left up due to 1. Laziness and 2. Maybe there will be a vacancy when someone manages to reach them and 3. Discourage people from building more rentals because there are already so many. What, you don't believe? Just look at all the 'for rent' signs.

Lastly, most of the places for rent at a good price are either already taken or very small units or just crap places. I wish you the best of luck.
