I like to measure returns on not just positive cashflow but also depreciation/tax benefits, principle pay down, and appreciation.

We use specialized software to measure occupancy and revenue, based on actual bookings for the market as a whole..... we're happy to send occupancy/revenue reports on any specific properties you might be considering!

I've never had an issues, it's just an extra safety measure.  

Can't measure that either with a cf analysis.  

also the garage .. its not impossible to find that setup but it is more rare. it pulls -$50 per car spot off the rent or -$100 with no garage. that's accounted for with the rental comp.As far as the rear access being make or break im asking you guys on that one. that's the part im not sure about. its an otherwise great deal except these cost cutting measures by the builder. i didn't notice this before walking it yesterdayIm afraid im falling in love with the numbers and these weird things with the property will attract a lessor tenant than i want to deal with and ill be stuck in a nightmare property like i hear about people falling into on accident because they thought the numbers on paper were so much better but the property was crap and nobody wanted it . that's what im afraid of i guess.i did do extensive research on this particular neighborhood so i am familiar with the stats and boots on ground type as i live pretty close about 30 min .

Unless you have a lot (and that is a subjective measure), setting up all that might be overkill.

Based on all the feedback, I understand that's the smartest way to find deals and measure success.

You can't say that this was a positive thing to own if the sale of the property is trying to catch up to the accumulated cost of owning that property at the time of sale...and you don't catch up and pass the costs with the proceeds from the sale.Yes, you can say by its pure definition that the property is an asset as it stands, however, for this conversation as an investment, it is not an asset since the value of that asset as an investment must be measured from the beginning of ownership to the end...otherwise, there would be no problem as an investor to pay cash upfront and sell the property for less than you paid for it. 

Milwaukee has been one of the most competitive markets in the US over the last few months (measured in list price to sold price ratio) and the days where you could get a quality duplex for under 200k are gone.

Set actionable measurable goals/timelines and stick with it would be my advice on next steps.
