Why do you need an expensive complicated contract that is hard to get out of bought from a salesperson whose compensation is tied not to your benefit but to the highest fee product they can sell you? 

the fastest date I can legally have her out.Inform her (in writing) of this move-out date and offer to pay her $XXX to be gone on or before then.Prepare a simple one-page Lease Termination Agreement to be signed by tenant indicating she has voluntarily moved out in exchange for $XXX in compensation, further asserting she is terminating her month-to-month lease, has returned all keys, and will not be reentering the premises, upon pain of committing trespass.Have tenant bring keys to attorney's office, sign/date/notarize the Agreement, and receive her $XXX in certified funds.The minute the tenant is done signing at the attorney's office, I'd be changing the locks.Good luck!

However, good property managers need to be compensated for doing a good job.

When wholesalers state that they have "equity" in the deal that simply means that they have the property under contract at a price point that if and when they sell the property they will be compensated as the fee is already built into the price. 

Especially for me negotiating the compensation structure.

Any extra deposit or rent won't compensate the extra hustle you will have to deal with later. 

Tell the seller you will compensate at end of escrow the cash for key amount so everybody wins.

And that is how all the turn key marketing companies make their money ( if they are doing it legally) referral fees And for wholesalers to me its just the HIEGHT of stupidity not to be able to list properties or get referral fees.I remember one post on BP nice young couple from Salida LA ( just over the lake from N O  they spent all this money on direct mail and were chronicling there efforts on BP  and within a few months they had referred no less than 6 sellers to their agent friend for no compensation.. and you don't see them on BP anymore I suspect they flamed out like 95% of wholesalers do.. spent all that money on direct mail only to give the business away.. just weird to me.  

If they are a performer that wants to excel and do well then the compensation is there.

That too says to me that you'd be best served by either purchasing into a well structured syndicated LP or LLC project with enough upside to compensate your tax loss (because you will not be able to 1031 into it).
