Yes.

You can attend open houses without being preapproves. Although, Realtors will take you more seriously if you are approved before hand. They will spend more time and effort with someone whom they know is ready with proof in hand versus a "lookie lou" so to speak.I am available to get you pre approved. www.rhayes.slsmtg.com, is my website with online application, rhayes@slsmtg.com is my email address.I look forward to working with you.

Yes you can, the pre-approval letter will help your Realtor place an offer on a home when you find the one you like.
