Linda, I agree with Gale. you want to work with an agent & get pre approved with a lender prior to even looking at homes. I can do both or either for you.
I would suggest, that as a buyer, you Google every agent that responds to your question here on Trulia, learn as much as you can about who they are online, read their client testimonials, so you know what their clients are saying about them, and then give us each a call and just ask us why we think you should work with us instead of another agent. This will take you a little while to do, but will be time well spent, as choosing the right agent is the first step towards choosing the right home. Then, pick the best fit for you and let them go to work for you with the skill and knowledge that they have. I hope to hear from you soon.
Good luck, Jirius Isaac
