I can't find any four-plexes. What should I do?

[Drue Jaramillo]

I've been trying to get a small and decent start in REI. After some reading and listening, I decided I wanted to go with renting. I took the advice of Brandon Turner, and I though I should start with a four-plex, and I would build up from there. The problem is, I can't find any listings on my searches. Have you guys found any somewhere? If not, do you have any suggestions for where I should start my investing instead? Any advice is helpful.
