There are a lot of variables involved in the cost of a rehab that vary from market to market.  

Tax benefits will vary greatly depending on an investor's individual circumstances.In short, if you are looking to invest for cash flow, COC is the figure to know!  

This is relatively common in my experience and the terms can vary significantly.  

Obviously this will vary depending upon the property, but are there some general guidelines for how to anticipate this expense in the event that I am unable to obtain the information directly from the seller?  

Okay here's the deal, i'm 22 with a two year associates degree, no debt, no current income(unemployed, living at home), and perfect credit.

The fees, like you listed below vary by PM, and I would say more so by the area. 

Finance the house, pay the note, do the repairs yourself and cash flow the rest.Answer can vary like crazy!

I *think* if you have a degree and are employed in your field then you don't need to wait 2 years to count that Income.  

The contractor labor rates for the area will be dictated by some degree to how construction has recovered in your area.

Thats seems fair as either party can simply vary the option terms e.g. reduce or increase monthly lease.
