In a county in NC, I've heard estimates of $20K-$25K per pad (not including land costs), but the Midwest is probably cheaper.

I had an engineer to a preliminary concept site plan and we can potentially get 36 pads on it.

thinking of meter panels at one main location and simple 50/30/20's at each pad.   

Some general guidelines: $15- $20k per pad for utilities (water/sewer/electric) and then there are the road coasts.

We usually do a rough budget as follows:City W/S: $50 per pad/per year Cap Ex1 Private Ut: $100 per pad/per year2 Private Ut: $150 per pad/per yearAgain, this is only rough numbers.  

The long pants will not keep the fleas off of you.You need to duct tape wrap around the shoes and hands before going in the property.Set off a bunch of flea bombs.If the carpet is bad you will need to replace it and the pad because of the eggs that will rehatch.Depends on how old the carpet is.After leaving the house they throw away the suit in the trash before getting in the car to leave.Otherwise they can track back to your house where you live.Ken you can try to make tenants do flea collars and all of that but good luck getting them to comply.People are going to live how they live no matter what you say.This is why it's important to see how they are living where they are currently at.People can look polished in person but there room can look like a hurricane hit it.For these people there work persona and there living at home persona are worlds apart.

I buy parks that have upside in some way, pad rent, expenses or mis management issues.

All of this eye wash really isn't necessary, your business plan starting off can be three paragraphs with a supporting proforma statement to a lender, they are about the only folks you'll need a business plan for, except for your internal operations which can be on scratch pads as to you thoughts of the day. :)

In reality we know this is much harder to do but I tried to finance a park that had a 33 pads and 26 pads were individually owned in a small metro area (less than 25000 population) and no lender would touch it. 

I would love to be making about 500.00 a month in passive income to pad our current income and free us up to pursue some big dreams (like building our own home on our own land.)
