I have just been creating a word document to highlight some of these metrics for a market but creating an spreadsheet would be more effective and efficient. 

So grow revenue and be cost efficient. 5) Prepare to be disappointed a lot :) Wish you the best ...

Josh, to me that would be most efficient way to follow someone.

I am trying to find the most efficient way of locating people with delinquent taxes more than buying properties at the auctions.

I run a web/software service company, but have always had an interest in real estate.I'm also interested in getting more involved in the real estate community to find ways to "marry" software and real estate or improve current systems -- to help owners, agents and others in the industry make more money, manage properties better, work efficiently, etc.Thanks for reading and look forward to making new connections,Marco

I have been much more efficient at contacting leads and posting properties.I have been able to get up and running for under $20.

Is there a more efficient way I can be working the numbers?

The difference is going to be in your mindset, how you approach tasks, how diligently you structure the pieces around your investing, etc.When someone talks about "treating investing as a business," they generally just mean to approach investing with the goal of expanding, scaling, optimizing and overall just making things more efficient. 

Using pen and paper to organize my leads is not as efficient for me anymore, and I'm trying to incorporate more systems to automate my business and track my lead flow.

Since there market is not efficient, there are also arbitrage opportunities when you compare comparable units in a given building or complex.One of my recent deals was a $45,000 condo south of Seattle.
