Trying to find cash on cash

[Jack Srimani]

Hi,
I have checked out a SFH in one of the suburbs of Chicago. This is a 3 bedroom and two and half bath house. The house is ten years old and is a short sale. The asking rate is 125000. The rent in this area for this kind of house is 1400 dollars per month. The home is very well maintained and no work is needed for renting it out. The tax is approx 3000. The insurance is approx. 700 dollars. The renters in this area is high end ones who are willing to pay that amount of money for rent. With this scenario does the fifty percent rule apply? Does this seem to be good deal? I appreciate any help.
Thanks.
