If a prperty has delinquint taxes and is not in that auction, keep an eye on it.

I have had an eager eye on three properties in the metro Detroit/Flint areas (Clarkston, White Lake and Commerce twp) and noticed they all went "off market", and there doesn't seem to be activity at any of the properties. 

@Bryan Otteson Thanks Bryan, yes it is really exiting, we have started renovating two of the units, so this project will certainly be an eye opener for me.

# of units: 20all 1 bedroomall 360 sq ftasking price: $379k, down from $399kyear built: 1995 (pretty rough shape though)current vacancy rate: 30% (6 of the 20 units are vacant)current rent: $125, collected weeklylocation: decent... this property is probably the worst eye sore inside of a 3 block radiusworking class area... some gang-related concerns... all in all a pretty solid town expenses: all utilities... approximately $1,900 / monthrepairs needed: not sure at this point... 10k-20k would go a long way in improving the look and appeal of the property and would likely reduce vacancy ratecap rate: 9-10%Based on the numbers, this is without a doubt the best property I've looked at, but I have a few questions:What are the best ways to reduce vacancy rates, generally speaking?

I definitely have my eye on properties that rent for $ 700 plus.Thanks again for your thoughtful response, much appreciated.

There are no "iron clad" wholesaling contracts and non-refundable is eye wash, not reality.

@Tom MoleVery glad I could help and your math has opened my eyes and things are starting to get clearer.. 

However I am keeping my eyes open for plex opportunities there in the west end like you found.  

I kept my eyes open for areas where the median household income has been rising, (I used this as a temperature gauge for the quality of the neighborhood) and areas where the 2% rule was most likely to be found.
