Hey Gavin, It sounds like you're incredibly driven at a young age, which is commendable.

I like to cast a wide-net....so I post my rentals on Zillow (and since they own Trulia, it also syndicates there), Redfin, Apartments.com, Realtor.com, and Homes.com. 

The main guide lines focus on it being on a permanent foundation (Concrete slab), Hurricane tie-downs if you are in FL, GA, LA and a few other states, must be a double wide and not moved from another location.

@Jeremy H.This was so thorough and actually incredibly helpful.

Hi Christina, I've personally found Columbus Ohio to be an incredibly promising market, especially for fix and flip investments.

Wow, this question is wide open. 

A 10-foot-wide house was built 'out of spite' on a leftover piece of land in Florida and is selling for $619,000.

My only complaint is that they couldn't stick to the agenda to save their life - as an event planner myself, It was incredibly irritating.  

Additionally, finding a mentor who's achieved success in buy-and-hold investing can be incredibly valuable.
