How do you manage properties remotely if the need arises for an individual to physically go and see a tenant, say for example, they don't pay rent and stop taking your calls?

There are plenty of other articles as well. 

I wrote an article a few years back that detailed the costs (at that time) to get your real estate license.While they vary from state to state, it still gives you a good idea of the amount of fees associated with getting your license.

I have read a lot about advantage of claim "active participation", but no article about any pros on NOT claiming active participation.I have placed a couple of properties in service in 2019 and will have a loss that can offset up to 25,000 active income assuming i claim active participation (I am not a real estate professional and I know I cannot claim "material participation").

Shop around and read articles on the internet.  

A good person should be able to give you a close estimate without having to physically see a property.

I am just wondering if i am missing anything that i should know or what other investors do to look at different areas, thank you for any help.Any books or articles that can explain this in more detail for me would help as well.

Because an article from 2016 by US News also states that 1099 workers can contribute 25% or 53,000; whichever is lower.

I want to share a few thoughts I have and then link to a few recent articles so you understand what we may face here.  

Does anyone know off the top of their head if there is a podcast about investing with friends or any good articles?
