A lot of lease problems start with a tenant making what seems like a reasonable assumption. A family member stays longer than planned. A small dog arrives before the tenant asks. A slow leak is ignored because there is a bucket underneath it. By the time the landlord hears about it, the problem is harder to solve than it needed to be.
The rules worth explaining most carefully are usually not the dramatic ones. They are the ordinary rules that feel obvious to a landlord but can mean something different to a tenant. Those are the places where a five minute conversation at move in can save a difficult conversation later.

Guests and Additional Occupants
Tenants often hear a rule about unauthorized occupants and think it only applies to someone formally moving in. Real life is less neat. A partner begins staying most nights. An adult child comes home for a few months. A relative needs a place to stay while looking for work.
I explain that normal guests are part of living in a home, but the lease may treat someone differently once the home becomes that person’s regular residence. If the tenant is unsure where that line is, the right move is to ask before making assumptions. That keeps the conversation about the lease instead of about whether you approve of the tenant’s family or personal life.
Pets and Animal Requests
A tenant may think a quiet cat or small dog is not a meaningful change. From a property management standpoint, it is still something that needs to be handled through the lease. Flooring, landscaping, odors, damage, and insurance can all be affected.
Explain the approval process before an animal moves in. If the tenant later raises an assistance animal request, handle that through the appropriate process rather than treating it like an ordinary pet request. The important habit is the same: contact the landlord before assuming the answer.
Small Maintenance Problems
This is one I see constantly. Some tenants do not report a slow leak, a weak air conditioner, a sprinkler problem, or water showing up near a window because they do not want to bother the landlord. Others assume they will be blamed for the repair.
In Austin and the Hill Country, waiting can get expensive. Long stretches of summer heat put heavy strain on HVAC systems. A condensate problem can create water damage. Thunderstorms and hail can expose roof or window problems, while sloped or rocky lots can make drainage issues more obvious after a hard rain. A small plumbing leak can damage cabinets before anyone realizes how long it has been there.
Tell tenants you want early reports. They do not need to know what caused the problem. They need to tell you what they see, where it is happening, and whether it is getting worse.
Changes to the Home
People want a rental to feel like home, and that is reasonable. The confusion begins when a tenant assumes a small project does not count as a change. Mounting televisions, installing shelves, painting, replacing fixtures, adding locks, or changing landscaping can all create restoration work later.
My rule is simple: if the project changes a surface, fixture, lock, system, or something that stays with the house, ask first. Written approval protects both sides from having different memories at move out.

Everyday Responsibilities
Air filters, lawn care, trash placement, parking, irrigation schedules, and HOA rules can seem minor on move in day. Six months later, they are the details everyone remembers if they were handled poorly.
Show the tenant what applies to that specific house. If the filter is in a ceiling return, point it out. If the property has drainage features or irrigation controls the tenant is expected to understand, show them where they are. If street parking creates a problem in the subdivision, say so before the tenant has guests over.
The habit I want from a tenant is not perfect memory. It is this: when you are unsure, ask before acting. A tenant who does that is trying to follow the lease, and that is a much easier relationship to manage.
