Recently switched employers.

I personally don't think there's a good one-size-fits-all answer for that (I think few here would claim there is).

Ask your boss how much it costs to employ you per hour and how much he bills out for your time.    

To determine the market resale value, utilize Craigslist, Land Watch, Land and Farm, EBay, Zillow, and/or any other other online resource to collect comps for vacant properties of similar size in nearby areas.

So based on providing a common access driveway and minimum lot size he could actually only fit about 12-14 units/acre and 18 units...big difference.

The problem comes in when you change jobs and one employer calls it a bonus and the other calls it a commission.  

I'm full time employed, so being hands on is kind of tough...  

The factory is on the west side and there is plenty of employment opportunity on that side of the city.

I am self employed and looking to invest in rental property In El Paso, Texas.

Being self employed I'm not actively searching for another deal, but I'm keeping some dry powder just incase.
