Tenant not paid rent regularly and maintenance charges

I am a senior citizen of 71 years, and living with my mother aged 96. I am awodower and left my Row house 3 Parsn Apartment, Madurai for rent from Feb 2022 to March 2023. The tenant has not paid maintenance dues regularly and has not paid the rent in time as per rental agreement. My house needs repair in the floor due to cracked tiles and sinking in bed room. I asked the tenant for vacating the house from 2023 March onwards, but he has not vacated the house and did not pay the rent for 5 months continuosly and I suggested for adjusting the advance of 5months rent against the dues in rent. However he continued to occupy the house and occasionally pays the rent at his will. Now for the past 3 months rent was due and after, repeated reminders, paid 2 months rent and has not paid mantenance dues for 12 months upto November 2024. I could not able to leave my aged immobolised mother at Chennai and no assistance is available to keep her in safe custody. My repeated reminders through wattaapp to the tenant do not yeald any result. Kindly advice me. I have not renewed the rental agreement after March 2022, owing to pending repar works.
