Example: Posting states they need someone who can communicate well and enter data into a property management software.

The problem I've had with Rentometer is it uses a distance radius for data, which in this case mould encompass Lower Merion, etc.. it might be better for larger suburban towns where there is less variation within blocks.

Note that the intuit business model is to get you to use the internet version and charging you a monthly fee to access your data versus one time software cost.

It does offer some protections, but there are plenty of stories about people losing.I am not an expert nor a lawyer, but there is lots of data about it. 

You need good data to make good decisions. 

I'm having a hard time determining if that break even point is good or not, even if we miss one major week (Jul/Aug) I would hope we could make it up on the other months but I'm just not sure as the data is sparse because most people rent through the complexes rental pool so we can't find vacancy information. 

That said, he closes very quickly, gives me great REI guidance, pushes for a high appraisal based off data he compiles, and offers a 30 year fixed rate.

(Looks like all their data is coming from Zillow). 

Another way to look at it is the science (elevation data) vs the art (function and appearance).
