I respect your point of view as a tenant, but I can tell you as a landlord.

I want to be respectful of that. 

If you and I are both analyzing the same deal that is 1000 miles away from our respective homes, you are going to be nervous to lock it in whereas I will likely be a lot less nervous because I've done this stuff before.

Selling would trigger capital gains and depreciation recapture (15% and 25% tax, respectively) unless you lived there for 2 of the last 5 years.

Things like moving homes into the park to fill up vacant spaces, renovating vacant park owned homes (which is radically different than the renovation of site built construction), selling homes (along with licensing requirements), carrying paper in the correct fashion, crafting the correct leases and notices with respect to the landlord tenant regulations for MHPs, etc.  

Whatever it is, you have to respect the blood, sweat and tears (literally, sometimes) that it takes for someone else to finally become a 'successful' investor.

@Colleen F.has posted some items to consider with respect to consideration for the occupants. 

When you jump into any business venture with a family member you have to realize and respect that you now have two relationships with this person(s): one as a family member you'd probably do anything for and another as a business partner acting in the best interest of the business.

Plus i caught a guy taking my sign down (another wholesaler) waste of money.While i wait for my yellow letters to reach their respected audience I have been focusing on probate letters and learning lease-too options.  

Those threads are always most informational when the discourse is respectful.
