The city has ordinances about garages being left open and it's either install a garage door opener or give control to one tenant that cares and is willing to pay to keep it closed.

Did your agent tell you anything about rent control when you purchased the building?

For example if you're in rent controlled area, you may only bump up a little bit at a time.

It will be easier to control while you are still in VA.  

Maintain control everything you are responsible for.  

A huge thanks for BiggerPockets community, especially the emotional support when I was literally dealing with too many things and my mind won't stop and my mood gets swinging and less controllable.

Stay under control of things you are responsible for.Always remember to do the math analysis and try to look at prospect properties before you make an offer or at least put a ciause in the sales contract that allows you to make a detailed inspection and possibly back out of deal without a penalty that hurts you too much.  

Consider setbacks (from the property line), etc as they will control how wide and deep the house may be and how it will sit on the lot.

Why let any existing clients slip away for reasons within your own control.

The issue with this is that the competition is immense, and there are some big players that buy in these sales and don't mind driving the price up.
