Buy the cheapest piece of raw land you can afford (or a mobile home) and pay all cash.

The turn off for me was location (near mobile home park?) 

I want to build a large portfolio for it to become my career.I am in the process of getting a mortgage to buy a multi-family.I have also bought a house and wholetailed it for contract for deed.We bought a mobile home 2 weeks ago and we are going to rent it for a gross of $400. $100 of that goes to the lot rent.I plan to buy another Mobile home in a few weeks and I plan to sell it.

is 13.7 a good cap rate for a mobile home park for purchase price $399,000.

It could be good for buying mobile home parks but bad for speculating on land.  

Investments have included SFR and condo rentals, a mobile home park, and a hotel.

My goal is to move into investing in single family homes and mobile homes (rehabbing & wholesale).

I 'M NEW AND I NEED EDUCATION ON HOW TO BUY A MOBILE HOME PARK, ARE THERE ANY AFFORDABLE BOOKS OR CDS I CAN PURCHASE ?

,I think that the "anti-trailer" sentiment that is written into most local ordinances is lost on many investors who are outside of the mobile home investment sphere.

I have been involved in countless mold contamination projects ranging from mobile homes, to light commercial, to large and high-rise commercial, to educational environments (elementary through college level) since the early 90's.
