Are you still looking? And do you have to have 4 bedrooms? I recently came across a nice 3 bedroom, newer home in Crown Point available to rent. If you like you can email me at email@example.com or feel free to call me at 708-983-8315.
The more insight and information I have the faster I can find you a home to rent.
Are there any other area's that you are interested in? Are you familiar with the Lake County area?
I see that you are located in in CA and have children. If you go to citydata.com you can find great statistics and area information. Also if you go to my website firstname.lastname@example.org I also have a link to similar information on different area's so that maybe you can broaden your search.
I will keep you in mind if I come across a rental in Crown Point that meets your needs. Let me know if you are interested in other area's.
Have a great day,
