I'm not sure it will help me a ton to start but the data they are getting is great and I want to support their effort.  

I met a guy who inherited 3 rental properties and 2 rent to own properties.

Dave Meyer (BiggerPockets Data VP) mentioned earlier this year how it has an attractive Rent-to-price and population growth.

In filling out the data from the Schedule K-1, TurboTax is asking me whether I have passive activity loss carrovers in Regular Tax and AMT. 

As far as REI goes, I've only met a couple of shady investors over the phone while I've been marketing....So anyway, I found this pretty sweet place called the Music Cafe...

Until recently, I was able to pull data from the past 12 months to calculate higher or lower turnover rates to determine what neighborhoods had the best odds of converting.

This is obviously important on trying to learn about areas you're unfamiliar with, and useful for being able to help grade the neighborhood.Whats the best RE mapping software that cleanly/simply provides housing data and additional data like school rank, demographics, crime, etc.

Alternatively, you can use any of the vast number of Internet sites that provide access to most MLS data.

You should be good to go - your own data center.

I dont know how I could have done it without large data access, namely MLS to get a really good idea of market activity in the new area.Good luck!
