I recently used AppealTaxes-NOW.com to represent me in appealing the assessed valuation of two C class properties.

I would want the realtor who is an acquaintance to represent me.

Put each year's cash flow into adjacent cells and then use the formula =IRR(A1:E1) where the letters represent the first and last column and the numbers represent the row. 

I have clients from other countries and other states who is happy to have myself to represent them in there absence.

I plan to use the same listing agent to represent me as well as the seller.

I would add to @Roberto Westerband by saying that most short sales are by servicing companies representing trustee of securitized loan pools.  

From my experience, most portfolio lenders stay within specific geographic boundaries which typically represent that bank's CRA (Community Reinvestment Act) area. 

I dabble in all facets of SFR, but mostly work on personal investments and represent other investors.  

That represents a total ROI of 400%That didn't even include your Positive Cashflows.If you don't want to use simple calculations like the one in E11 to E16, then you should use the Internal Rate of Return Calculation which we can see if 29% per year for every single year of your 7 year holding period.I would say there are a lot of people on this Blog who will not understand these calculations and because of that, miss these incredible returns.My own several multi-Family properties returned even higher than yours..

They want a guaranteed $3500 commission just for representing you.3.
