Her lease ends 8/31/21, You've already noticed her to vacate so check with a lawyer and see if you can evict holdovers that don't leave.

I'm sure you can find some good advice on this forum, but speaking with a lawyer/accountant is going to be your best bet. 

If you end up needing a good real estate lawyer here in town @Ryan Jones (Jones Property Law, Edmond) might be able to help!

It can be done without the use of a lawyer although with fairly stubborn tenants the use of an attorney can sometimes light a large fire under the real ends of stubborn tenants.

You could ask a lawyer about the legality of signing a year lease with a one month penalty for breaking it early.

So, IMHO the likelihood of you needing the various protections touted by lawyers is near-zero. 

But IF I’m sued that sounds like an easy way for a lawyer to pierce the corporate veil of my LLC, which negates the LLC in the first place.

But i am a special case since i was an immigrant and wanted to fit in.

I'm not a lawyer but if the tenant breaks the lease resulting in an eviction then they broke the lease and are responsible for any associated costs resulting from them breaking the lease. 

@Allison MeggisonPurchasing property, you'll always want to go with a lawyer.
