In some cases the reasoning makes sense to me, as a property owner myself: it's not a smart business practice to rent to a tenant who is only in the country under a short-term status, who does not have proof of sufficient employment, who does not have a guarantor (we'd often just call them a co-signer in the US), and with whom the landlord cannot communicate (if the tenant doesn't speak good Japanese). 

They can go through underwriting, but a traditional mortgage will need a CO in place to close.

If one of us was on a loan for the rental property with a co-signer-based on their income. 

I really just got started here with a google search but you can also just go on the Airbnb site and look for a co-host.

@Tyler BodiI actually have a co worker who own a STR rental in the Highlands.

I have a co-op in Manhattan that I want to sell.

I was just in a co-working space on Valley St last week in fact.

Also, you could consider a co-signor.

So you could technically house hack a co-op.
