I have attended local meetups so that I can have a handful of experienced folks who have resources to share.  

Meetup.com is a good resource for those but some of the groups will also post here on Bigger Pockets Marketplace too.

Please recommend any books, or other learning resources on these subjects. 

BiggerPockets is full of resources designed to help you along your journey, whether you are just getting started or a seasoned investor.

I find it's very personal, and dependent a lot on your goals, resources, risk tolerance, location, experience, etc.

This is a great place to learn and to connect with people so take advantage of all the great resources.

If you're open to looking at some resources here's what I would recommend you start with based on what you've said:1.

Pretty cool stuff and I just thought I'd share some pictures and be a resource to anyone trying to do this as well.

I think behind tenant screenings and leases there is a quality of a landlord that's also as a person that is the respect for a good person and the intelligence of making fair affairs.For me for ten years in the past I had a house of 650sqft (two rooms and cozy kitchen) where I always have been giving away one of the room for others who were asking for help for themselves and I didn't had any earnings for me by that, and that has been during for many and many years, meanwhile I was surely needing more space for me, for my business in a studio and for my own personal life I eventually could have been having.Nonetheless this, on last years I had no more an house and I needed a room for rent, but even before any screening the landlords were being unrespectful and very unreasonably severe to me, they often had making me lose so much time by no taking or going away to the point I had no other choices in the end, and they set me in the wrong places for me, dangerous ones, too small, too big and very expensive, unhealthy ones or not providing anything at all when it was obvious they needed to.To me this kind of behaviour is very wrong, mostly because usually they are the same people who pretend respects and acts as they are very careful and attentive to housing situations in general, but with me, they have been lying above anything and just disrespected the person at a human level. 

Airdna is a good resource and tool, but I wouldn't rely solely on that platform for data.
