Joshua, since you've ALREADY been pre-approved, and if you like your loan officer/feel confident in their ability to get the job done, then you are now ready to seek out a real estate agent like has been mentioned, a buyer's agent. I'd interview as many as you'd like - but at least 3 of them. Don't automatically go with the first agent you speak with, even if they are eventually the one you go with... get a good feel of the different types of agents & their styles.
If I was a buyer, the info I'd want to know would be:
1. How many homes are we able to see in person? Is there a limit?
2. What neighborhoods/areas do you have above-average, specific knowledge of?
3. Will you be able to set me up to get listings emailed to me as soon as they become available, change price, etc.?
4. If I have questions about a specific listed home and you do not know, would you be willing to make reasonable efforts to find out?
5. When it comes time, what is the process for us to determine what a fair offer is on a home?
6. I am looking for [specific unique property type] (i.e. a home on a farm with a certain amount of acreage, a mixed-use property, etc.), do you have past experience helping buyers with [specific unique property type]?
Those are just the ones I can think of off the top of my head. Make notes on your cell phone, etc. whenever you think of random questions to ask and you should come up with a pretty healthy list.
Good luck with everything.
