My advice....do not think of applicants as people, view them only as a collection of facts and data, there is absolutely no place for personal emotions in business.

I would suggest hire a professional in Appfolio to train you and hire someone else to do the data entry.My question to you is why did you switch to Appfolio?

The biggest thing I look for is population growth and the most up-to-date data that I have found is on the US Census Bureau website.

Like @Jon Crosby I use Mint (got to love free accounting), but then couple that with MinttoReport (small annual charge), a great tool so you can export your Mint data and report it once you setup tags and categories. 

I have met a few of you on this thread but I will introduce myself.

AirDNA and Everbooked have pretty good occupancy data (you're limited in what you can get for free though).

Ok, so just did some research and initially, I was thinking RealtyTrac was the clear winner as they had TONS more info but BASED ON OTHER'S OPINIONS VIA GOOGLE SEARCH, it looks like they have a history of inaccurate data. 

I wasn't able to infer any new data from the public records.

Is there a way to access MLS data without being a real estate agent?  

Such a huge coincidence, I met a nice couple who were talking about your outback reia.
