I disagree with a provision that essentially prevents you from filing an eviction action until the 10th. I don’t know the laws in your state, but in California, you want to have the right to give a 3-day notice to pay or quit on the 2nd day, which gives you the right to file an eviction action on the 6th.
So, I would just say rent is due on the 1st and after that it is late, but late fees will be incurred if rent is not paid on the 5th.
Spell out who will pay each utility, trash, etc.
Any late fees or unpaid utilities are deemed “additional rent.”
All amounts paid will be applied first to any unpaid security deposit, then to any past-due balance, then to current rent due.
Any acceptance of payment from the landlord shall not operate as a waiver of any breach of the lease by the tenant.
Tenant shall be responsible for damage to the premises caused by tenant or tenant’s guests.
Make sure you have enough money stashed away to pay the mortgage and premises maintenance for several months in case your tenant stops paying but won’t move out willingly and is able to stall an eviction action.
Never let a tenant stall your eviction action for more than a few days with appeals to sympathy, a sob story, or empty promises.
Never lock a tenant out or cut off their utilities.
Take care of maintenance issues asap. Do not rely on the tenant to be there when you need to make investigation of the premises or repairs. Do the investigation or repairs anyway by giving proper notice of entry.
If a tenant makes a claim that there is a habitability problem, get a camera and post a notice of entry asap to document the alleged problem and so you can make a repair estimate.
Make sure each tenant is fully individually responsible for the entire rent.
Avoid verbal agreements. Get it in writing.
Get your hands on a good rental agreement. Try the law library.
In fact, get a landlord-tenant guide from your local law library and give it a good once-over. Understand what topics it covers in general terms and read through the parts that interest you. Take notes, photocopy pages. That way, if you ever encounter a problem, you know exactly where to look to brush up on the law.
