Good investment for 100,000?

[Rodney Swindle]

Hi! So I've been looking into real estate investing for some time now. I'm in the military and plan on using this career to generate ~100,000$ (under estemate) in capital soon. However, I cant decide whether I should invest in a multi-family home (likely a 4 plex), an apartment complex, or a trailer park. So far, I have decided: Multi-family homes are secure, but generate little income initially, large complexes are secure and generate large income but require more capital, and trailer parks require little capital can generate large income but are much less secure. I would also like some advice on who I need to speak with to learn the local laws and regulations related to this type of investment. Also, where can I look to "shop around" for milti-family homes? Thanks!
