There is so much cost to running a (any) business, even changing a light bulb is expensive for a PM.

The people teaching the class are teaching but they are not the ones that will implement the ideas to propel your success. 

Many will spend all their hard earned cash on training and not leave themselves money to actaully implement what was taught.

I usually recommend clients a pretty easy cosmetic rehab which is refinish floors, replace cabinets with modern white ones, add a white stone, new appliances, new bathroom vanity/mirror/light fixture and add in unit laundry. 

We have minimal resources as far as money goes, but we have a relatively long list of upgrades (window treatments, hardware, light fixtures, paint, etc).

Out of sight out of mind.If these were items you wanted to pass the cost down to the tenants--light bulbs, air filters, water filters, batteries etc. those should be defined in the lease agreement.

Quartz countertops are durable and widely appealing, and neutral cabinet colors like white or light gray work well.

We aren't even implementing what we learned because we are too busy dealing with a personal issue and haven't been able to travel much for the last couple of years.

Custom built closets NO wire closest.. lights in the closets upgraded electrical etc etc.

Light to moderate.
