It would seem that maintenance risks are only multiplied which is one of the main risks that pops into my head.

Now, here is a question that might draw a facepalm (esp those who know how street-to-street Cincy can be), but here's a question: Around Norwood, what would you say the typical 1) cap rates, and 2) gross rent multipliers, are you seeing for properties in that market (let's assume C class properties, or well cared for/ rehabed Turn of the 20th century houses in that area)? 

To calculate the B/S/H, you take the $140,000 ARV, and multiplied it by 15% which equals $21,000 [$140,000 x .15 = $21,000].You decided that your profit should be $10,000 as the Assignment Fee for a wholesale.The Investor Buyer’s profit is calculated by multiplying the Rehab costs by $1.25 to get $19,000 [$15,000 x $1.25 = $18,750].Now, plug all these figures into the MAO formula and you calculate that the most you can offer on this property is $75,000.

so far my only challenge that im facing to figure out is finding the accurate repair cost after multiplying property price by .7 suggestions?

To follow up @Christian M.Here are the multipliers for finding the area accounting for pitch.http://www.browningrg.com/sloped-roof-pitch-correctionKeep in mind there can be a significant amount of waste in roofing.

Multiply that by my 15 residential rental units and that added up to super savings and gave me reliable information to go on.

Quick math – Divide current SEV by the taxable value then multiply but the 2008 taxes (be sure to subtract out any water / sewer / garbage / special assessments before you do this).

I don't have a quick and easy multiplier to use.

From my understanding the Total Profit if Sold figure is calculated by taking the current value of the property and multiplying it by one minus the sales expenses for your realtor and then subtracting the current loan value and the cash you have invested in the property (i.e. any private/hard money you couldn't pull out when you refinanced into a traditional loan.

Multiply that by twelve months and apply an appropriate expense ratio.
