I'm assuming since you have a realtor she has told you to be pre-approved already. We had to look higher than we originally intended, but everything worked out, and that was over the holidays/into February. I'm sure there's a lot more on the market now since it's not around Christmas.
The area on the NW side of the loop is nice, but pricier. When you find the house you want, put in an offer ASAP, but don't feel pressured. Be sure it is what you want.
