i always thought that japanese make great tenants, respectful, clean, pay on time.

Also, does anyone use/have feedback on local Airbnb cleaning services?

An INVESTOR does not repair appliances, does not unclog toilets, does not paint walls, clean units, OWNER OPERATORS do those things, Business Owners/Operators do those things, NOT INVESTORS. 

A condition of the cash for keys should be that they don't leave behind dumpsters full of things.To me broom swept meant 100% free of belongings and actually cleaned albeit not deeply.

As @Charles Carillo said, you can make the most of that time, but most people just waste the 4-5 years and then end up doing something unrelated to their degree field anyway.Maybe look into a Trade School, like an electrical one....nice clean work that pays really well.

Since they are nearby, they would have local housekeeping and handyman contacts for cleaning and emergencies.

I'm a landlord of a 3 unit building and a regular check on it and clean the hallways lately.

After the first clean it did not look good at all.

Get electrical connected (electrician)4) Do any cleaning , painting , etc needed to get it rent ready4) Get a tenant!

The neighbor is outside cleaning up his yard minding his own business.
