When you go over the lease, provide them a tenant instruction sheet with your welcome packet that explains:- how they can pay rent- how to make a repair request- watering restrictions- how to operate unit's HVAC, thermostat, care of garbage disposal, location of main water shut off, gas shut off, breaker box- numbers or links to turn on/transfer utility accounts- how your city enforces noise ordinances and how this may effect those who violate it (BTW, your tenant  blasting his music so it can be heard at by other residents on the block  at 10 am is just as bad as if he is doing it at 4 in the morning). - anything else you feel tenant should knowOthers have given you some great suggestions for collecting rent automatically.

They must dispose of pet waste properly as well, in accordance with our property rules.

All of them also have dish washers and washer/dryer except for the 4 units for section 8. 1 of them have a garbage disposal - which I was told it's a bad idea. 

First and foremost you should write into your future lease agreements that there are penalties for trash improperly disposed of.

Tell them that you are concerned because the trash is not disposed of, but placed on the property in a manner that the children can get into it and that there is so much pot smoking in the unit that it is very noticeable. 

Also stay away from providing amenities, fridge, stoves, dish washers, washer/ dryer units and even garbage disposals.

I have collected exactly 1 in 25 years and that was from a soldier who had to have my signature to clear postGood luck and feel free to contact me if I can helpDoes Texas landlord-tenant law require a landlord to give proper notice to terminate a lease agreement that has converted to a month-to-month agreement and/or follow abandonment procedures before entering a rental unit, disposing of tenant belongings, and re-renting?

I'm willing to bet it's a bunch of old used furniture and nothing of real value. my process is to document what was left behind and then dispose of it, clean up the unit, change the locks, and rent it again.

Be careful disposing of the trailer without written authority from the former tenants or a judge.

@Nathan McDonald honestly if it were my rental I would charge $150 for cleaning and disposal of furniture.
