Being a townhome meant zero capex, a TOTAL of $600 in repairs (garage door opener and a microwave) and a newly signed 2 year extension for $3,500/mo for 2022/2023 zero vacancy. 

Furthermore, I can't figure out where to put a fridge, dishwasher, and microwave.

An upper end buyer will want to buy them (and has cash to do so) themselves.The dishwasher and built in microwave is an absolute in all properties.

I have a rental that needs a new Microwave Oven, and that unit rents for $1,600 a month.

As I understand it, the negligence comes into play if, let's say the over the stove microwave goes out, and instead of hiring someone to put one in, I swap it out with a new one and then a week later it falls down and hits the tenant.

Most SFH, tenants bring their own frig, washer & dryer, microwave. 

Coffee maker with filters, fridge with ice maker, corkscrew, map of the town on the fridge, extra light bulbs, a wall calendar, toaster oven, microwave. 

Basic kitchen looks rentable, BUT is there a dedicated circuit for a Fridge and a dedicated circuit for a microwave, are there enough outlets to be (modern).

For basic properties, I like a micro-hood over the range - takes care of 2 appliances (microwave and hood).See if you can find a good "big box" store for some other materials, like flooring and tile.
