Clarification on CAP and ROI Calcs

[Doug Haisten]

I did a search of past posts on these numbers but the calculations used general terms such as "Annual Income" and "Sales Price". I hope I am not carrying this to the Nth degree, but I have a question or two to clarify the calculation of CAP for a all cash purchase. I have a question about ROI too.

If CAP is the NOI / Sales Price of the property, what constitutes the Sales Price. For instance, if I buy a property for $80K but it needs $20K in repairs and 4 months of carrying costs and $10K in sales costs , would the total of these be used for the sales price?

If ROI is After Tax Cash Flow / Total Investment wouldnt that really be NOI / (Purchase Price+Repairs+Carrying Costs+Sales Costs).

Thank Everyone
