However, if a conversation like that needs to be had, I should have been done in person, in a non-confrontational way, and with your best interest at heart.

the problem I confronted in past was the local banks will not work with me because at the time I had 5 mortgages.  

It's better to confront the issue in advance than spend the money and hope the seller will either A-adjust the price B- provide a repair credit or C-fix the items prior to close.

Economic Update(Monday, November 23, 2020) When COVID-19 arrived, all of us were confronted with an unexpected pandemic that upended the plans we had for 2020.

I used to be extremely confrontational and very assertive.

The last thing I would want is for the furious person to go to my house and confront my family when I'm not home. 

I have no problem confronting people, but if this dude is scary or scares away good tenants, it could create financial problems.

Or maybe have the visit and never mention it because you want to avoid any sort of confrontation at any cost, only send an official notice about the rent increase a day later.I know multiple hobby landlords who have screwed this particular pooch when dealing with their tenants. 

Today this, tomorrow that, and then no communication for 4-5 days.When I confronted her about it, she was just nonchalant about it.

I know it depends on the individual but I'm staunchly in the owner camp for the same reasons as @Bryan Otteson and @Theresa Worsham.I'm a non-confrontational person who hates conflict but, since my policies are fair and logical, I have no problem representing them as my own.
