I agree with the other responses- lending isn't a great place to start- it's complicated, risky and requires deep market knowledge to not be taken advantage of. 

Many parks due require residents to have insurance on their homes, if owned.

They do tend to require more time managing and ensuring that your rental rates are competitive based on current STR availability/rates in your area.

However, I'm unsure how to ensure that the homes meet cleaning requirements when I can't personally inspect them.

Most investors goals are more modest perhaps to replace their W2 income and get financial freedom and that doesn't require 100 doors.

There are plenty of programs out there that will allow you to create a state-specific lease with all of the required language for your state and will also let you modify it to add your own special terms, like your parking requirements, quiet hours, how trash and utilities will be handled, etc.

The ownership and use periods do not need to be consecutive.Exceptions to the Two-Year Rule:If you're selling due to a change in employment, health reasons, or other unforeseen circumstances, you may be eligible for a reduced exclusion.In cases of unforeseen circumstances, the IRS may prorate the exclusion based on the time you spent in the home.In your situation, if you sell the property before meeting the two-year ownership and use requirement, you may not qualify for the full exclusion.

I have no specific properties in mind as of now, but wanted to reach out to all of you and see what factors I should be looking for/at once I am physically there.

Does anyone else have experience with this and if so what are the requirements?

Its a trade off compared to buying something that needs work - this would require a larger up front investment for a larger cash flowIts not a good or bad strategy, its more about what is more important for you right now.
