Do I serve her a 30-day notice to vacate the property...

If it's for non payment, they you post a "pay or quit" notice.

So my question is what is the best course of action: 1) Give notice to vacate after X days if the rental agreement isn't signed?

As a resident of Chandler, Arizona it's hard not to notice how fast our home values are appreciating over the last year and continue to rise.

She said he will be out in less than 50 days and that was including the 30 day notice.

You can do 30 day's notice if you want, but honestly in that circumstance, I'd keep the rest of that month's rent and as long as they were out, I'd give them the rest back (minus any damages). 

(I've just placed a tenant) I've heard a lot about Cosy.co but I've noticed they are merging with apartments.com I'm looking for software that offers reporting on-time payments to there credit report. and also facilitates payments.

Provide them a year's worth of filters when they move in, written instructions, and a notice that they are responsible for repairs if their failure to maintain results in a problem.2.
