Property management is a good deal if you're not going to be fixing anything yourself, or do not have the time to bother them for the monthly rent. You just pay the percentage and they handle all the BS, repairs under a set amount, etc......you just get a check every month. I'm part of a great one in STL, but do not know anyone in KC. Just make sure you find one that is licensed--they're usually part of a real estate brokerage (that's the way ours is.)
Insurance will actually be cheaper since you're not insuring all your stuff inside the house--just the building, liability, etc. The rent will have to have their own policy to cover all their crap. You don't have to require it as they might not be able to afford it. Not your problem. And if the place burns down, they're going to sue you anyway.
Check with your local municipality or fire district on the occupancy permits and things like that. You might have to change a few things to CYA if they're not to current building/fire code. Smoke detectors, CO detectors, etc.
You need to tread lightly around your mortgage, because you most likely signed a document saying you were going to occupy the property and not rent it. They could technically say you breached it and call the loan, but that's not going to happen in this market.
It doesn't matter where you own property, it's about where you plan to stay. If you're living in hotels, you can still maintain residency in MO. You need to talk with a CPA to take full advantage and a "out of town / travelling" worker. There are ALL kinds of deductions. Laundry, hygiene products, meals, etc. Travelling nurses clean up on this. If you're subject to any DOT limitations, you can claim 80% rather than 50% too.
Get all the details together and find a really good CPA. They'll be able to tell you the best course of action.
