You may want to look at a place called Candlewood Suites in Cedar Park. These are fully furnished hotel rooms you can rent for extended periods. They may be the easiest choice for your circumstances but I am not sure the cost. These types of places are for extended stays so they have discounted rates the longer you plan on being there.
Good luck to you and if you need any help I have lived in Cedar Park for over 7 years now. It's a fantastic place to call home, especially if you already have family in the area.

Another place to look is HomeAway.com and VRBO.com. If you don't mind driving about 15 minutes to get to your daughter, I would suggest looking at vacation rentals in Lago Vista and Point Venture. Most of the rentals are right on the lake (Lake Travis).
Hope this is helpful.
