Jackson County, MO Eviction Question

[Fernando Marquez]

I have a small house , not very expensive and a not so good area.  Rent is $500 and I bought the house to wholesale it but it was a good deal and the renter has been in the house for 8 yrs.  The Oct. payment was late by 1 week and the Nov. payment was 2 weeks late and she paid the $50 late fee.  As of this writing she has not paid for Dec. and has not answered any of my calls or responded to any of my texts.  I am just trying to get her to respond and work something out and have told her.  I even sent her a letter, but nothing.  I have no idea of the eviction process in this area and need to learn.  Aside of hiring an attorney can someone provide the best approach or guidance on this possible eviction?

thanks
