Sorry I can't recommend a reliable realtor, There use to be a really nice lady on this board, AudreyGuer or something along those lines but she seems to have disappeared.
I know of 2 friends in 1 beds in International one is paying 27k and one is paying 31.
It is around 20kms from Dubai, the road isn't as busy as lets say the road to Sharjah so commuting isn't nearly as bad even though they are similar distances.
Arifn you may get 4k a month but I'm guessing the realtor who sold you the place is the one that said the rents were worth 75k.
Good luck to you both 🙂
