Pulling Comparables - Systems to Use

[Clayton Natho]

I'm in the process of developing my business plan for the purpose of finding and acquiring buy and hold single family (possibly multi family), for the purposes of building a passive income stream in and around Houston, TX.  

One of the things I'm currently try to figure out is how to pull good comps when I'm looking at deals and what it will be worth.  

Currently I'm taking a hard look at:

Real Acquisitions - www.realaquisitions.com

I also saw through internet searches a website called propelio.com

Is there any other websites or any other tool that anyone has found to be a good tool or resource, especially specific to the Houston area?

Any and all comments welcome!
