There are more than a dozen full trash bags accumulated in the back yard. 

Within two weeks we were rat free, never to return mostly due to closing the trash can and not placing trash bags on the ground next to the can.Rats don’t just hang out for fun without a food source nearby, they are smart and actually spend most of their day grooming themselves – go figure. 

Brewed my own coffee and brown bagged my lunch.  

We attend the christening or first birthday party if invited.We give gift cards for the Holidays.We help decorate for the Holidays and contribute to community potlucks/BBQs (at our 8-plex).We have a "make it your own home" policy, whereby we give approval for a reasonable modification to the property, such as painting a room, changing out a light fixture, etc.We prepare a "move-in packet" which includes information to orient them to the property (property rules, utility contact information, change of address form, our contact information, etc. ) and also information about the neighborhood, such as a walking/trail map of the local area, chamber of commerce welcome information, a list of nearby amenities (including medical, shopping, restaurants, schools, parks), menus for local pizza delivery services, coupons for local businesses, etc.We prepare a "move-in gift" which consists of a bucket of our favorite cleaning supplies and a reusable shopping bag with starter supplies of paper products, a "Zip-It" hair snare for clearing sink drains, a toilet plunger, a cutting board, approved hanging devices (picture hooks), a door mat and a shoe tray.We supply light bulbs for all permanent light fixtures for the duration of the tenancy, including specialty bulbs for appliances and chandeliers.

Finally, depending on your return strategy and risk spread, different markets is something you may want to consider, for example you may want to spread your eggs beyond your immediate territory to enhance your buyers market experience, I know I may open up a bag of worms with my next statement, but consider turnkey operators in different market to help enhance your buyers market experience.

I am just trying to help the seller and I dont want to leave them holding the bag as it were.

Hire a high school kid to bag up your trash.

A good tool to have in the back of your tool bag, but not a feasible primary strategy for me I have found.  

Brown bag your lunch and change your life.  

I would recommend a 'mixed bag' approach.
