The number of rentals available has dropped by about 10% over the last 8 months
Houses start at $250 per week and for that you can get a renovated older style home in good condition
So no great drama of rentals through the roof
Rent is controlled by the ability of the people to pay, if the rents are too high they will stay with relatives or share or move to a place where it is cheaper If the investor is getting a poor return on his money its just his/her bad luck but it has no bearing on the rent that can be charged
