There are a lot of great people in this industry and you'll have no problems finding people willing to lend a helping hand. My suggestion would be to learn from everyone who is active in this space. Personally, I listen to the Frank & Dave show every week and I also listen to @Jefferson and @BradJohnson's podcast every week. If there was more out there, I'd listen to that as well. @Andriy_Boychuk and I have known each other a long time and he networks with everyone. It's actually not surprising that you two have already connected! Definitely follow his example and start networking with everyone you can.
The link for Parlay 2.0 turns Google Earth into a GIS system so you can largely ignore county records sites if you end up using it. You should also consider outsourcing the databasing to a virtual employee via UpWork. The last thing you want to do is tie yourself up with databasing that you don't have time to study due diligence procedures, network with investors, speak to owners, develop refined marketing strategies, learn the business, etc. Just get a system for marketing put in place so you can focus on higher and better uses of time. You are, after all, trying to buy more than one or two parks. Outsourcing a complicated task like databasing is great practice for managing a business so there is a ton of value in not doing it yourself.
You can always email through here if you get stuck. There's not that much to the research side of the business and it might benefit you to go hang out with a RE attorney or at a title company for a few days to learn how to do online research. You only need to get it down enough to find and train the right person to hire. Eventually, your employee will know it better than you anyways.
