Data/lists you pull matter.

The biggest ways IMO are MLS data, multiple solutions for sellers (off market cash deal or listing), ability to rep. yourself on your own deals (saving on commission).Commission savings adds up fast when you're doing multiple deals a year.That being said, there is cost to having a license so if you're only doing a couple deals a year then it might not make as much sense.

My rent data is also based on CoStar and other social media outlets' marketplaces.

Direct access to MLS data, multiple solutions for sellers (off market cash deal or listing), ability to rep. yourself on your own deals (saving on commission), and of course, education & networking.Having a license costs $$$ though.

research market data for the top and bottom averages of property value appreciation data in your area to find out if it's worth it to you.

Hey Kendrick, we use Propstream for property data and Smarter Contact as a CRM for text and voice campaigns.

look at other STR data in the area and do similar style to do your best to recreate similar results 

I have not had an issue until this week on Airbnb and I'm going to use the Wynd data as evidence since there was no physical evidence so we will see.

If you do not have data/comps to find out your post renovation value, that ads a huge risk, and makes the move less valuable. 

After that, I would encourage you to go to your county recorders office / court to request data yourself.
