Hello Laura,I have actively purchased land that I identified for the last 10+ years.The easiest way to find out if the land is for sale is to talk to the owner directly.You can use tools such as Whitepages.com surprisingly they have over 90% of people's cell numbers.If you can't get the owner on the phone, I would send them a letter asking them if they want to sell, I have seen other people use actual contract offers that they send out to the owner trying to purchase the property.I would not share my concept unless its some sort of Charity that you are either seeking a partner or donation for.I haven't used PropStream, However one really good tool is called Land Glide, its and app on your phone, and you can look at the parcel makes in real time, and also see the owner info and for each parcel.Hope this helps,Dustin 

I am sort of tired of "I am a good tenant because I pay on time" so do an "X" for me right away; basically treating a landlord as a room service. 

The same deal falling onto the lap of an investor without cash or access to quick credit, would at best end up giving up half the profits and at worst get a small “finder” fee.1.

Also - is it appropriate to add a contingency related to this in an offer - specifically something like "earnest money will be returned if property soil is not found suitable to support 15 RV pads" sort of thing? 

Agreed but if they sell a property, that’s less fees they’ll collect every year and you’d want to sell the worst property which would be a significant hit.

All sorts of liens can be placed on title. 

But can the contract/note/agreement have some sort of clauses to  protect the seller stating that Property can no be resell on contract while in subto or something like that?

And without uitlities on you need to project the worst case, because there will be hidden damage. 

I might be concerned about regs regarding this sort of thing.

Knowledge is power and worst case you'll discover it's not a career you want to do but have a better understanding for how it all fits together.
