Flat roofs do drain, but not nearly as efficiently as a roof with any kind of pitch.

i'm looking for the forum's advice on the most efficient/effective way of weeding out properties. i'll be living in the property for at least a year. while i live there, i'll be living in it (so property can't be a complete rehab), fixing or improving the property, and then either flipping or renting out the property. i've looked at about 18 properties the past 3 weekends (i just started 3 weeks ago). the 18 properties were chosen based on 2 broad criteria: 1) based on pictures, description, and google street view, choose properties close to the metra (in illinois), in a location with a great high school (>=8 score), and in nice(r) neighborhood.2) look at zillow for an idea on property values in the neighborhood so that i'm not buying one of the most expensive houses in the neighborhood. if i feel the house i'm looking at is somewhat undervalued because it needs work and there's some room for me to flip, then house passes.this criteria has helped me weed out 100's of properties, but takes me a bit of time.i'm curious, is this a good start or are there other ways that the full time/professional investors use?

Are you looking for someone to do the most cost-efficient work to make it a rental, or higher-end work for a primary residence?

Can it be done without their service, is it an efficient and effective method to collect data "real time" in one place with enough value to warrant the monthly fee?

I can provide insight into the best practices for a smooth and efficient project. 

The free time I have outside my job is never used efficiently.

I loved making things, and I loved being in management and coordinating and building an efficient organization.

Short runs for specific difficult locations (for one outlet) aren't too bad, but using flex for trunks will severely reduce efficiency.

Most include solar panels as the primary power generation source, solar panels are becoming cheaper and more efficient every day.

You will look prepared and efficient.2.
