I'm unsure of your background but having skills in graphic, print, and web design would be huge to get an idea of what to do in an ever-changing field.

For example, a house with 11 - 12 rooms (5 BR, 3 Bath, living room, sitting room etc) will take at least 30+ pictures to showcase every room and if you are a destination like lake front, then you will have show case outside also.

Threads like this showcase how difficult it's been to find deals.

If I’m a passive investor, I need more than a simplified graphic. 

You're utilizing the food to showcase your produce you're selling.

(in case that graphic is as small after posting as it looks right now: http://www.dustinanderin.com/SalesPics/valuation.jpg ) Also important - I have $34522.39 in cash on hand in various deposit accounts.

The template is the basic graphic look and feel of the site.

If this community feels that there are pain points in the property management software out there and is willing to provide desired requirements to ease the pain, I could consider putting the software together that would benefit most as long as there is enough support :)If this concept generates enough interest, we could probably start by doing a google hangout to showcase what I have now, while gathering your feedback to tweak the process so that we're all in the same page before developing the first version of the webapp(not google sheet).

My question- how do you showcase your success as a small/medium investor to grab the attention of a professional network full of potential investors?
