Thanks for the history lesson and unnecessary lashing rhetoric regarding favors, but he posed questions in a manner that clearly triggered you ...  

I still charged her rent (about 80% of market rent) and I paid the same, putting both in my landlord checking account should any unnecessary expenses come up with the property.

Rents are trickling in for May, despite the courts being closed, despite the governor's well-publicized, completely unnecessary proclamation encouraging not to pay rent for 3 months. 

I want to start small, learn the ropes, and avoid taking large unnecessary risks.Any advice on how to get started (meetup recommendations, reading suggestions, etc)?

But I can sleep well at night knowing that I am not taking on unnecessary risk.  

Questions is, if the City audits could they impose tax on the assignment?

Most will commit to 4 years b/c moving during school is an unnecessary pain and is expensive.  

Because it seemed unnecessary to you until this post. 

If you do end up purchasing in the HOA to run it as a long term rental, make sure to have a clause in the lease that makes the tenants financially responsible for any fines imposed by the HOA that result from the tenants' actions. 

Long story but they were trying to force me to do something unnecessary that would've impacted me financially in a big way and would've caused me to waste a lot of time.
