What are my rights under this kind of situation im told when i can and cant shower cause it interfers with niece water pressure.  

If it is extra living space keep in mind that if you choose to go with just the concrete floor - it might be very cold in the winter.  

For example if you can but a house for (real example of one that I bought in May) $19,000, with owner financing none the less, paying out $549 PITI w water and sewage in that number, and you can rent it for $850 per month, then you have positive cash flow. 

I don't necessarily agree with going only SFH if you want to get into commercial, but there are a lot better ways to test the water.  

Using my homemade calculator (copied from BP calculator) and your expense inputs (assuming no property management fees, and renters pay water, sewer and trash and zero fix up cost, 20% down) and the assumption you are trying achieve a 10% cap rate, I come up with the exact same  max offer - $109,200.  

There was a case in Cape Coral Florida where the home owner wasn't connected for both the water and electric.

We replaced hot water tank, walls, doors, vanities, fixtures, etc... 1b) Do I need to break down my pre-market expenses into the Schedule E categories or can I leave them in bulk under "supplies" and "services" like I currently have them?

.$25k in materials and laborMonthly holding costs: $557(int payments, taxes, utilities, insurance)House info as purchased:House built in 1971 - Solid B neighborhood - Great Schools2081 sq ft4 Bed, 2.5 BathNew RoofNew WindowsNew HVACVinyl SidingWork to be performed:New cabinets and counter topsLaminate downstairs and carpet upstairsNew vanitiesNew light and plumbing fixtures(tubs staying)New water heater Paneling removed from den and replaced with sheetrockWindow removed from eat in kitchen and replaced with slider to access the back yardSmall deck built off of sliderAnd obviously paint throughout.We will probably price it under market value and hope to sell it quickly(30-60 days) at $125k which would give us a profit(after commissions, closing costs, and carrying costs) of $22k-$23k.  

The regulations have gone out of control and the storm water management alone will run into the 10's of thousands.

Our only other significant monthly obligations are water and electricity.
