It's hard. All you can do is apply, apply, apply. Keep yourself glued to realestate.com so you will be able to get your application in fast when new properties are listed.
Have copies of all your i.d and documentation scanned on a flash drive or on the computer so you have everything ready to apply each time.
I wouldn't say any of the last 3 houses we rented 'ticked all the boxes' in terms of what we really desire in a rental. The first was on a busy road near a club, the 2nd was in a less desirable suburb & our current home is quite old and has zero renovations.
Sadly, it is sometimes necessary to lower your standards in order to snare a property.
Keep your chin up and be persistent. Good luck
