You have two options, you can either have your housing provided for you or you can get a stipend (housing allowance, per diem rate). You just about always want to go with a stipend. I just made a post about this here;

The Portland, OR County is Multnomah. For that county the maximum per diem rate is $179 a day. Most companies like mine avoid the confusion of monthly rates and put into an hourly rate. To get that figure we combine both the lodging rate and the meals and incidentals rate which is that $179 figure. Then we take that number and multiply it by 7 (days in a week) then divide it by 40 (hours you’ll work in a week) and that would be your hourly tax free per diem rate. The most amount of tax free money you can make in Portland would be $31.33 an hour. This would be $1,253.20 a week net or $5,012.80 a month. I’m working with an OT in Portland and gave her the maximum per diem rate. You should be getting it too.
You can’t always get the full amount of per diem (depending on the county you’re working in) because of the bill rates we get. For instance, right now the max per diem rate in NYC would be $64 an hour tax free. There’s no way you’ll ever get that. That figure is not to far off from our bill rates and we have to pay you a taxable portion in your hourly rate as well.
Just curious, did you get the Trinity Mission Health and Rehab of Portland position?
Hope that all helped, if you have anymore questions feel free to fire away.
