Website has been great.

Website looks pretty good too!

@Ned Carey I see that, this website is awesome ! 

Craigslist is an amazing website for networking with people that want to buy, sell, or get rid of stuff.

Zillow, trulia, realtor.com are all good websites to get a ballpark of your value as well.

After reading about the HouseFlippingSpreadSheet on J Scott's web site I am thinking about buying it since I am planning on doing my first rehab next year.J's recommendation goes a long way IMO but I was curious if anyone else has any suggestions or advise about this product or any other similar products they use and recommend.

@Nick Foundas Often, though not always, the Every Door Direct Mail Route on the USPS website will tell you how many homes are on the route.

Some counties web sites are more user friendly than others you may have to look at a tax parcel map and search by the parcel in the search function.  

Some take commercial breaks and pitch stuff like hard money lenders, business credit, virtual assistants, landlord services, deal partnering, websites, marketing services, home security devices, etc.
