I just added laundry to a unit and need to update the lease with a laundry line item.

Strategies include offering owner financing, allowing trade-ins, or providing lease options.

And when you do a lease for MTR, you'll need to put that in the lease in case they stay through high season, spelling out exact prices for each calendar month, so there is no confusion and it is legally enforceable. 

In Oregon you can kick out who ever is living there unless the federal law regarding arms length leases comes to play..

But that's not very frequent.

I did my own lease agreement.

You have to purchase in cash and you can only stay in them 28 days per year because the HOA runs it like a business and leases the HRH name but you do own the deed.

The office space added represents a saving of $2500 a month I was going to pay in a lease for an offsite building for my expanding team and staff.

You can only play games for so long.Chances are your next door neighbor is an IRS agent and turns you in when your tenants blocks their drive or some other random event disturbing your IRS neighbor.ADU catches fire and your insurance won't cover you, because it was an illegal and unpermitted structure.The city inspector told the last guy not to build or rent it, and is now pissed and wants to make an example of you and just red tags the whole property and no one can occupy for the next 1-2-3 years while you wait for a hearing.Then when you get the hearing, "staff" recommends you tear the whole structure down, and if you still want an ADU, you can apply for a permit and rebuild it.Your tenant quits paying rent and won't move out and you can't evict them, because there is no valid lease and they're just your "roommate".Probably a dozen other bad things can happen to you when you do stuff like this. 

@Jae Yoo you should read your PM contract very thoroughly or even hire an attorney to do so, before thinking you can just break it.How would you feel if a tenant just broke their lease with you?
