Tenants should certainly take responsibility for maintaining the property and promptly informing the landlord of any maintenance concerns.

Rents can’t realistically continue to appreciate at the rate they were if we are to maintain a healthy housing sector.

Nights, weekends, holidays, etc.To keep this on-topic, though...DO figure out what's healthy for you to manage but remember it's a process where every experience teaches you good and bad (and be patient with that process).DON'T sweat the small stuff (damage/costs under $50, undisclosed dogs, etc.) but DO find a way to learn, prevent, put in better practices to maintain your sanity. 

For example, using 70-80% leverage could preserve your cash for more deals while maintaining strong returns.A blended approach might work: pay cash for smaller deals to avoid delays and borrow on more significant properties to spread risk.

Since they are responsible for maintaining the relationship with you after the transaction closes, this approach adds an extra layer of confidence and security to your investment. 

Along the way I've learned a lot of trade skills as well which goes a long way helping to maintain assets. 

I know that the west coast has lower cash flow with the higher prices, but seems like you are in a good spot if you can maintain that average.My state doesn't have state income taxes, what a blessing! 

That is something I would for sure have to look into as, according to your post, it seems like the timeline for mid-term rentals kind of lines up with the amount of time that we would be gone each year, which would work out well and probably require less of a hassle of trying to maintain the property after each stay for Air BnB.

AND the side you live on you can rent out a room or two depending on the number of rooms in your duplex or you have the option to maintain your privacy and sanity and keep it to yourself.  

Sometimes the tenants are coming from shelters or other communal type of housing where maintaining a space my not be solely there responsibility so maintaining the unit may not be to your liking.
