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. 

I wrote myself some software that allows me to model all sorts of what-if scenarios including market corrections and crashes.For example, I just ran a quick comparison of buying $100K properties with just slightly positive cash flow ($25 per month at the time of purchase) one per year as a Nomad.For the base scenario without a crash, I modeled appreciation to be the same as the historical Case-Shiller inflation rate of 3% per year.

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

For the record it looks to be a late 80's model Catalina 22 sail boat.

UP to $xyzK salary, the wording conveys a commission or fee for performance type compensation model.
