Especially the court house step or sheriff auctions.

Ya the beginning steps have already started.

I am new starting out in wholesaling and I’m curious to some of the skip tracing methods that can be used when looking to contact owners from your list of potential sellers.

How many posts and forums do I have to read to give me a Step 1, Step 2, Step 3, etc....learning map....This is my opinion.   

I wouldn't know the first thing about starting up an REA but interesting idea. more or less looking to find those that know more or are a few steps ahead of myself so that I can watch and learn. 

Also, I don't know your area, but I would use several valuation methods to determine market rent, and not just rentometer.

if you follow the Frank and Dave method of POH valuation, they will recommend that you put very little valuation on the POH at all, because as you know the MHs don't really retain value and for every dollar in lot rent collected your likely to put most of that back into the home that you own to a tenant that is more than likely wont take care of the property.

Take it a step at a time and don't try to reinvent the wheel, we have many successful people in real estate you can copy their strategies in your area.

Since I can't locate and set fire to the offending unit, I'm hoping there are preventative steps to keep them at bay. 

Trying to find deals in Chicago is extremely tough and although I am a new investor I've realized that if you want an actual "deal" where the numbers work, especially for a buy and hold play, one has to be creative and look to unconventional methods to source deals.
