Landlord Tenant

Is it lawful for the landlord to increases rent because the tenant joined a tenant union?
My landlord is a sick guy. He is been troubling me since the day I joined the tenants union. Now for no reason he has increased the rent. Is it lawful for my landlord to do so?
Can I ask my tenant to dispose of the waste and garbage himself?
I rented the upper portion of my house to a young guy. Until now, I used to dispose of his and our garbage together. Now, I don’t think I’ll be in the house too much to do all these jobs. Can I ask my tenant to dispose of the waste and garbage from now onward?
If the rental agreement does not fix a definite term, what will be term of the lease?
What if the agreement doesn’t speak on the time period of the lease? In such cases what will the term of lease be? Would like to know Iowa law in this regard.
How much amount can the landlord charge as late fee for unpaid rent if the rent is less than 700 dollars?
I couldn’t pay the rent for the last month. So I owe my landlord 450 dollars as rent, which is already a big amount for me. The landlord now wants me to pay him a late fee of 20 dollars per day. I find this amount a bit too much for late rent penalty. What is the law on late fee in case of unpaid rent in Iowa?
Can the landlord deduct payment of rent due from the security deposit in West Virginia?
My tenant didn’t pay rent for the last three months before the lease got expired. He is a nice guy so I didn’t make a fuss about it earlier. Now he says that I can deduct the rent from the security deposit. Is it legal to do so in West Virginia?
