Regarding moving a mobile home on the land, you'll have to check with your local zoning office to see what restrictions there are on the land (if any) when it comes to removing the older home and replacing it with a newer one. 

I can't speak to pricing off the top of my head, but check other rentals and compare. 

Check the blog below as I recently wrote a blog post about it.

You still check references, past landlords etc (if applicable).

I also recommend checking out the Hollister market.

Did you check to see if there are 3 rental licenses?

Make sure you check out the official website: https://miami.mercedesbenzplaces.com/ - the website you posted is by a broker who wants to represent you.

Have you checked his business credit? 

if its too good to be true it probably is. i never do any of these programs. anyone that sets a timeline on real-estate success is not genuine, there are so many circumstances for each individual investor that determine that trajectory.the only person making a good investment in 3-6 mos is the guys taking your checks.
