The answer is going to be based on my mobile home bias and opinion.
If your goal is passive cash-flow in as little as 30 days while risking little to no money then it is my opinion that you will capitalize the greatest by beginning with mobile homes in parks. Once you have proven this model works and you enjoy doing it, then you can pursue mobile homes attached to private land.
Approx. 25% of mobile homes are located in preexisting parks
Approx. 75% of mobile homes are located on private land
Mobile homes inside preexisting parks and mobile homes attached to private land you will own are two totally different animals with completely different ways of attracting sellers, finding buyers, structuring purchase offers, seller follow-up sequences, closing procedures, and reselling strategies.
It takes about the same cash and credit to get started in either so perhaps market for everything and making money whenever your phone rings in a good solution. Learn both strategies and be ready to help all sellers.
Love what you do daily,
