Now I am not suggesting that you let the tenants live there for free or pay rent as late as they want, but I think there are 10 simple things you can do that will keep them happy. And happy tenants will treat your property better, pay their rent on time, stay in your property longer, and recommend you to their friends as a good (possibly great) landlord.

Be friendly, respectful, and courteous always. Then when you need to be firm, they will know you are serious.

When handing the property over - make sure the property is really clean (spring cleaned) don't hand something over in a condition you wouldn't want to find it.

Answer your phone when the tenant calls or return their call promptly. Nothing is more frustrating when you have a question or problem and someone will not return or take your calls.

Make it easier for the tenant to love the property and retain the services of a garden service and pool service company upfront and include this in the rent - this way you get to keep the property in great condition and because the services are contracted to you - you can keep tabs on the condition of the garden and pool.

Call to just chat and see how they are doing. This lets them know you care about them as a person. Ask about their work, their kids, or what they enjoy.

Repair everything in the unit that the tenant calls about. Even a simple dripping faucet can fester into a frustration in time.

If the tenants have lived in the property for more than 2 years, touch up the paint in the main areas, paint a room a color that you both agree on, or get the carpets cleaned. You are not only keeping them happy, you are maintaining your property.

If the tenant always pays on time and they call and tell you the rent is going to be late, forgive the late fee this one time. Even the banks do it!

It is cheaper to keep a tenant than to find a new one. These simple (and in many cases free) tips can keep your tenants happy and make your life as a landlord easier.
