New cabinets, appliances, and counters in kitchen.

My game plan is to rehab it as a single family (so that it will pass the inspection) but to have it setup so that it can easily be made into a duplex when ready (put up a wall and add an additional kitchen back to back with the current kitchen).

It may mean I need to install a small kitchen and bathroom.Any information would be much appreciated :)

Also, keep in mind that the NJ standard for move out is "broom clean" which as far as I can tell is an uninformative and nearly meaningless term that gives you no information about removing grime from the kitchen bathrooms, cabinets and refrigerator.  

Everything is cosmetic except for the kitchen.

Then you may be stuck dealing with occupants that refuse to leave, stolen appliances/fixtures/cabinets, a place that's been trashed, outstanding liens that you weren't aware of, etc.I heard of a young lady that got excited about foreclosures about four years ago.

When I moved it I had electricity (which I barely used except to run appliances, and I mean that my monthly bill averaged $30), heat (which again I barely used...nothing that cheap sweatshirts and blankets can't fix if you're just sitting on your computer looking at BP), and running water...and in this regard I literally mean running because I had a 4 foot hole in my dining room ceiling with a plumbing leak and a red Solo cup to catch the drip while I slept on an air mattress on the floor.

Needs minor work such as flooring, paint and kitchen remodel.

Works like a dog (washing cars, cleans restaurant/hospital kitchens after closing).
