Buildium just bought All Property Management, a lead generation site that we use and like, they are working on some integration tools with CRM and lead maintenance.  

@Neil G.I've used http://www.idxbroker.com/ in the past and it comes to about $30-$75 a month, depending on what additional tools and services you subscribe to.Personally, we're starting to look at not including the IDX integration directly into the site and just linking folks to a page with the search widget provided by themls.com, included with you MLS subscription.

If you're willing to get down into the weeds and learn just a bit on the way, all the tools Google gives you makes it hard to beat Google Sites IMO.The interface isn't nearly as intuitive as Squarespace, but I'd say its at least as easy as Wix and you can do much more.

I spent a few bucks at the hardware store on some cheapo tools and the least expensive products I could find.

For all of you using a Carrot website--which we plan to move over to in the next 30-60 days--which CRM software are you using?

 @Bill Gulley  I had some interest in learning lease options to have that tool in the bag if the right situation presented itself but I've been unable to figure out all the details to make it legal.  

I'm curious if there's any tools or obvious formulas that could help me understand turner impact of property taxes in a rental property I may buy. 

Its a great tool to have.

Be wary of review services that waste the bulk of the reviews by capturing them into their tool instead of them going to the review sites people are on (people rarely review twice).

This is another great tool but it costs money.
