I was a little hesitant to pull the trigger also, as I was researching and saving properties, but wasn't really sure how to take the next step. I researched some investor friendly real estate agents in the area where I was looking to invest, and luckily found someone great almost immediately. I am so glad I did because despite the fact that I thought I was going to be so picky, my agent actually helped me to find something that I liked so much, I made an offer within one week of working with said agent.
A few things I had in place before I engaged-
1. An idea of my 3-5 top zip codes, and why I had selected them
2. A budget range, with details on how I would be financing my deal
3. Property criteria/ IE i was specifically looking for a 2-3 family that needed some work but didn't want to do a complete remodel
4. My agent was able to put me in touch with an awesome home inspector, and actually had a list of different ones to choose from with information about each :)
Good luck!
