I rent in MM and I can say that the rent on my house hasnt changed in over two years. I have been here for over a year now and just resigned for another at the same rate. I also know it didnt change from the last renter who was here in 05-06. It isnt an amazing house or anything, but no change between 05-08 is a long time. But what does the LL care? They bought forever ago and it produces cash, monthy. Why worry about an extra $50 and possible push good tenants out?
