This is a quick back of the napkin feasibility that will help you determine if the concept will work in your area. 

Pure speculation, could this be the new potential roommate who wanted to see the condition of your tenant's room to be sure they keep their room in sanitary condition?  

I didn't happen to crunch any of the numbers, but after reading his post, I did some quick back-of-the-napkin arithmetic, and the numbers certainly do appear, shall we say, somewhat optimistic.So here's what I want you to do.

This "hey here's another that meets our criteria, let's buy it" approach led us to do all the transactions outside of any corporate structure.Some back of napkin math says that next year when we fully realize all our 9 units of income personally will be quite interesting.

Some of those variables are the size of the park, number of vacant spaces, number of POHs, number of vacant POHs, number of MH spaces, number of RV spaces, the park amenities, landscaping and trees in the park, the age of the park, underground infrastructure age and condition, park location, size of the market, demand in the market, water or well, sewer or septic, other utility sources and whether or not they are direct billed, deferred maintenance, cost of management, and more.However, there is a quick "back of the napkin" way to evaluate a park that will usually tell you if the deal is worth a closer look.

Then a disability group took over two more spaces doing daycare work-therapy for handicapped adults, they also collect & sort bottles/cans, wrap napkins with cutlery etc for hotels/restaurants & are very busy.

The biggest piece of advice that help me break the metal block I had towards contracts was the fact that you could scribble something on a napkin and as long as you have 2 signatures (yours and someone else) its a contract!

Again, a lot of this is napkin math, but I couldnt see giving up a gold mine like that. 

Obviously these are napkin numbers but you get the jist of it.

Pretty soon, you'll be able to spot a deal with some basic math on a napkin or in your head.At the same time, save up cash.
