Landlord Tenant

I live in a rented house in Texas. I pay the electricity and water bills as agreed between me and the landlord when we signed the lease. Recently I had an argument with my landlord over something and the very next day he broke the water pipe that connects to my kitchen and now I am not getting water supply in the kitchen. Although my landlord apologized and agreed to get the pipe repaired he has not done anything about it thus far. I want to leave this house and go somewhere else. Can I terminate the lease in this scenario?

I signed the lease agreement two days back. I am yet to receive a copy of the agreement from my landlord. Within how many days is the landlord required to provide a copy of the lease to the tenant in Texas?

My tenant has failed to pay his rent for this month. Per the lease agreement, he should pay his rent on the first of every month. Can I charge a late fee for delay in the rental payment? What is the law in Texas in this regard?

I rented my apartment in Texas to a business person. The tenant had informed me in writing that the leased apartment will not be his primary residence. He also gave me his other address where he lives most days in a month. I am planning to increase the rent for my apartment. Should I send the notice of increase in the rent to his primary residence or the leased premises?

I live in a rented house in Texas. Until now, I used to pay my rent in cash, now all of a sudden my landlord has asked me to pay him the rent via check. I find it inconvenient and prefer cash payment. What does the law say in this regard?
