I would be buying a 4 acre commercial piece for ~$100 in the southwest part of Oregon, extending the city services a few hundred fee up the state hwy at a cost of about $70K and starting with ~20 or so full hookup, gravel-finished pads with room for up to ~50 sites down the road.

Possibly pouring a pad and just building a canopy of sorts so it was at least covered.  

If you could increase average rent by $50/pad and lower expenses by $25/pad, that will add $1,275 to Net Operating Income (NOI).

Anything with the little blue dot lines under the word will display a definition if you hover your mouse over it. 

The $250 is really me padding for worst case scenario.Also, with the repair figures, I'm trying to account for surprises.

I set up a property website through Wix, then posted on CL, Postlets, (which sends out to Zillow, Trulia, and Hot Pads) and Zumper.  

this works in my 15% cap rate (after all pads) market of ScrantonI do my math like thisRent-10% maintenance-10% vacancy-10% management-hard costs- $75/door= amount for mortgage.Mortgage at 6.5% at 20 years tells me finished valuethat minus repairs/updates tells me the max offerhalf that is where i start.

I paid $800 for 20x25 pad with a depth of 6 inches just for the concrete. 

A mouse can be standing right next to an elephant but just because it is right next to the elephant the mouse is certainly not the same things as the elephant and with real estate properties can be very different even if right next to each other. 

Look up PAD Rentals in London - they are a PM firm and a good bunch of guys.
