Since they’re the same company now, i assume they’ll eventually merge the interfaces & functionality

Banks don't use the term "ARV," unless they happen to be people that browse biggerpockets.com. 

I have started looking around and browsing the resources available, and learning about the industry, generally preparing to make by first investment in 1-2 years when the timing is right.This is all great, but I have questions regarding market research and how people here approach it.

It may sound a little like overkill, but for me overkill probably isn't possible given where I want my level of involvement to be in performing active field duties and tenant interfacing, which is ZERO.That is all very valuable to me as it allows me to focus on my professional work and securities investment which is what I prefer to do.

I particularly enjoy browsing through county records although I'm not sure if it's the most effective method.

I have more free time then I would like, so I spend countless hours browsing the internet to find blogs, books, videos, and discussion forums to learn from.

I think you can get it, but not through the usual browsing county tax sites. 

@Patrick Britton I think you will find this varies everywhere...all my assumptions on our Inn were at 30% occupancy...if it performs at 70%, we'll be golden...There is a site called Air DNA that has this data for your area...paid of course, but good user interface for sure.

Is there an online interface for tenants/owners?

I have smart locks and cameras on the property so I think that interface wouldn’t be too bad.
