Part of appeal for purchasing is that fact there are existing pad sites with water and sewer hookup in place. 

I was also told by random friends and family that I should write off my electricity bills and water bills but I feel like I'm getting bad advice there?

They were built in 1948, fully permitted and have separate electric and gas metering and share water and sewer service.

That would leave me $1,233.00 net minus $225.00 for garbage and water/sewer.

'New' is not necessarily maintenance free you can have backed up toilets and water damage in any age building.

Flood plain. 

Water heaters and one furnace are brand new.

You are already short $50 per month, so no roof, appliances, hot water heater, hvac, bath and kitchen remodel.

Now, I get my April water bill and it's $2500! 

This is the list I've got in mind:The plumbing system.The electrical system.The structural condition.The heating and air conditioning systems.The basement and foundation.The roof and attic.Evidence of water penetration or grading issues.Appliances and other general components of the home.MoldNot sure about thesePests such as bugs and wildlife.Environmental issues such as radon, asbestos and lead paint.2.
