An RV park came to mind as well as there are existing slabs from the previous mobile home park that was there before it was forced to close due to the flood plain, but I am not sure that it fits the local demographic for that area where the land is located as I don't see many of the locals having RV's to park and store.

And construction loans are going to want a larger down-payment (i.e. 20%) versus only needing maybe as little as 3.5% to purchase an existing MF property where you will live in one unit and rent out the other(s).And a construction loan to build a MF property may be considered commercial development (even at 4 units) versus building a SF home to live in yourself - and if so, they may want you to have prior rehab / development experience to some degree.

I noticed that many towns/cities doesn't allow STRs and existing ones might be functioning illegally.

So rather than "guess" at the price, get an estimate or two.When you are paving asphalt over a gravel road, you are talking about a "from scratch" job, as opposed to adding an asphalt overlay on top of an existing asphalt surface.

People think I'm a Portsmouth basher, but the fraud that exists in every level of their government is for real. 

@Gavin Welch Cozy has been shut down to new users for months and all existing users are being transitioned to Apartments dot com.

The property management contract with existing owner does not state it???? 

Does someone has experience with self-showing tours with smart locks or even when an existing tenant shows property to a potential one?

On the other hand if you are wanting to be 100% or close to it debt free and get the purchase price covered from the profit/equity from the existing place than it might be worth selling and buying another place - may be even out of state - North Carolina or Floria or may be even some other states.

Inspections should include electrical, plumbing, and septic/sewer contractors (to address the underground infrastructure) but also can include pool, home inspections, asphalt, and more, depending on the park.
