paying too much for what precisely? 

Applying the 50% rule to this property it looks like we are running negative, however since this is a brand new home, we are managing it and demand for this type of rental is through the roof I think that this rule does not apply, is there a more precise calculator anyone could recommend for estimating costs for newer homes?

However, @Brandon Turner wrote a great book on precisely this topic. 

With several cooks in the kitchen we may be able to get something precise without being overly complicated to use.

I can't remember when Fannie/Freddie announced they would no longer purchase loans that didn't include a FICO score, but I remember it caused a big brouhaha in the industry, for precisely the reason that now explanations for the contents of the consumer's credit report would be irrelevant.

Where that pump maybe placed in line. need to be precise on where to put pipe and outlets. is the a window in a wall I have to put an outlet in.

Which seems to be precisely what you just supported with your comment above.  

@Michael Swan to be precise i would say that 2-4 units are MFR but are not Commercial type. 

Use a calculator or spreadsheet to see the precise details.

@Tony Montano, I was thinking of coming back and being more precise in my answer, especially about what exactly "capital gains" consists of.
