List that I've personallly used or have heard others utilize include, BiggerPockets, Deal Check, Rental Software, Valuate, Real Data, and Calculator.net.

The radius approach could include more than 1 neighborhood (especially if there is an "accross the highway" scenario), I have access to propstream, flipster, and others but none of these tools actually have neighborhood data what tools are you all using to get comps in the same neighborhood? 

We are in the process of completing our taxes and our tax agent is requesting a lot of data and is estimating about $650 to complete our business taxes, which seems pretty reasonable.

This information is invaluable!

We are looking into a potential short term rental on the North East side of town, trying to gather more data on type of visitors to the area?

We pulled the county data and sifted it via excel. 

I'm seeking the data to evaluate potential cities to focus on.

Is there a platform out there that I can see my properties in a visual way and see how they are doing by the data I input?

As such they are not as focused necessarily on accuracy of data in particular when it comes to being up to date.

This breaks down to propstream for data (just pay once and pull a bunch of data), batchskiptracing for contact info, and Mojo for a dialer.
