if she aint paying she can't stay !!! simple as .........
Dont renew the tenancy - it will then go onto a Statutory Periodic Tenancy - which means you can give her two months notice, and she can give you one months notice.
i would give her notice - issue a Section 21 and get rid - you dont need to be banging on doors to get paid. Take a witness with you - otherwise she may call your visit harrassment. you will need to be very professional in all this.
have you got a deposit ?
i would join national landlords association and get their help in completing a Section 21 notice - if you get it wrong by poor self-completion - you pay £150 to the court to try to get a Possession order, and if one date is wrong on the form , the judge throws it out and you start all over again with another £150
membership of NLA is a tax deductible expense and you also get cheaper house insurance as a member.
good luck
