The first few months I booked a hotel room. If you do it far enough in advance you can get pretty good rates. I was getting Marriott for $70 a night. 14 days a month that's $980 a month. After a few months, I got more familiar with the area and found a furnished studio rental with utilities for $850.
It eats a hole in your pocked to have two homes but if that's what you gotta do, then you gotta do it. I wouldn't do that if I weren't single with no kids. I would have gotten a bigger place and rented out a room to cut costs, and probably would only have to pay about $650 a month as my next step but I left before that happened.
