Please recommend the rental model I can opt, resources to learn. 

I use Evolve because it fits my STR business model which relates to how much I can spend on a management company, advertising, etc. and how many hours a week I want to put into the business. 

I was also wondering what flooring type/model did you use. 

However, if you model what the above mentioned park did, you could likely buy an RV or Mobile Home park that was already zoned as such. 

But the lure of tax free $ if you move in and take advantage of sec 121 as @Katie Lepore, was saying is powerful as well.To use a model where you move in and take advantage of 121 your pace will be slower. 

A prudent investor, which I aspire to be, shouldn't care if the market crashes, corrects, or continues upward.

I am looking at purchasing a new build condo that has not yet been built and there is not a model home that I can look at.

I’m a child abuse detective with aspirations of acquiring buy and hold properties in the next 12-18 months.

My real estate career started long before I had any aspirations to become a real estate investor.

I'd recommend that you just do the duplex model for now.
