Both of your ideas presume that the landlord has all control in a leasing relationship and that a tenant is in such a need - they will bend over backwards to make this deal work out (for the landlord). 

Let your agent know that you now rent the place and ask if your home owner's policy needs updating.You can prohibit pets, they chew things, bend window blinds, disturb the neighbors and make wet spots if left unattended.

I believe La Pine is in the path of growth for the Bend area and prices here were 100k-200k less for comparable homes.

I'm extremely Sedona STR savvy, as it's 95% of what I do and even I have to bend over backwards and really hustle to put together transactions for my clients that yield these results.

This state bends over backwards for tenants and as soon as the tenants have something to hold against you, they could and it would cost you much more than the rents you have been receiving.

Signed contract with contingency that renters will vacate in 90 days.Updates along the way were renters found another place and have been moving stuff out.90 days is May 30 and just received word that the renters will not move out now.I assume our options are to back out or bend to the will of the renters.Renters are paying half the market rent (that will not even pay the mortgage let alone expenses) and I have a very limited time to rehab the house before putting in new renters.Any advice?

Don't expect them to bend over backwards or at all to help you out.

I love Boise and my dad has property in Bend so would be a natural market for us.

Have you found a way to bend that 60 day move in rule a bit so a buyer can start a termination after closing instead of before?

We bend it a bit further by not warranting the appliances (we're not in the Maytag repair biz) and appliances are getting more and more expensive with more parts.
