However, with savvy keyword research, you can quickly learn how to stay ahead of the game.

I looked at OKC a bit but I'm just not sure the demand for STR's there is sufficient.I'm looking to get a property with short term stays, 7 days or less.

Any advice for that would be appreciatedThe only advice is to stay away from MFs.

If you are with a cloud brokerage like eXp or Real, you can just move and stay under their umbrella with a new state broker after you complete whatever Illinois needs for reciprocity.If they don't have a TC team, you will need to complete and upload all of the paperwork, but they should have compliance videos for you to do.

A lot of investors prefer to stay in the C class because that is where you get the best cash flow. 

It would be difficult for anyone to claim an STR is not residential with that definition.The difference between STR and MTR or LTR is the length of stay.  

It specifically calls out stays of less than 7 days, though.

Hell, my family came to town to visit and I bought furniture and they all stayed there before it was mine :-)

If you didn't, seems like a bad / inexperienced accountant to suggest such a thing.In my opinion, its the same as telling someone to go to a trade school and get a new career.A STR can help you lower your taxes but I would only do it if you were planning to purchase a STR.A STR is a business, you are responsible for furnishing the house, responding to guests, providing a great stay and experience, etc

He says it's in good condition, could use AC and a heater, maybe some new siding but otherwise in good condition.He has a renter there paying $1600 month to month who wants to stay but has no long term lease.
