Stuff that may radically change your opinion of things.

Sometimes using an LLC or similar setup can change how the income is taxed.

Thinking of changing landlord carpeting to some type of lvp before renting it out.

We all know how things can change. 

We change water every 3 months.

Sometimes the asking price does not reflect what's actually going on, there's a tenant, there's a change in the seller's situation, etc. 

I think you should change PMs because you have multiple complaints.  

Quote from @Treza Edwards: I would be looking at this as a market-dependent change.

If the unit is empty, change the locks, clean it, and get it rented.

This allows entry without a key, and allows me to change the lock as needed if I don't want someone in there.As an agent, I provide contacts to my clients who will do these things, and occasionally I will do favors for past clients who need someone to open the door or quickly supervise an appointment; of course not all agents will do this or for free.
