It really depends on your market and the owner's needs if sub to is even possible.

Depending on if you qualify for the special allowance for active RE, you may be able to take up to $25k in losses (unless you are full time in real estate and may be able to use real estate professional status). 

Depending on property titling one partner can get the conventional financing and the other can make a gift or use their assets for the remainder.  

I also find that depending on the tenant, my one Airbnb property has less wear and tear because it's constantly cleaned and maintained versus my other rentals where the families living there settle in and accumulate stuff - which makes it hard to deep clean regularly (to my liking) as well as just the constant daily wear and tear from kids etc. 

It defiantly depends on what area you're looking into.

@Ella VolneyTypically, you can only find a lender in the country where the property is located and, if you're not a resident there, it will be more difficult if not impossible, depending on the country.When it comes to investors, they need to be open to the idea and then you need to have opportunities that fit within their right risk/return profile.

Enactment of the clause depends upon the lessor (landlord) agreeing to the colors and rooms to be painted.

Depending on when the STR was placed-into-service, depreciation will be prorated based on the amount of months remaining the tax year. 

Highly depends on the particular community. 

It would be volume-dependent.
