Monthly Trash and property upkeep issues, advice?

[Aaron Lawson]

Hey all, hope you're doing well!  I have an apt bldg. challenge and looking for opinions from others, here is the scenario

1) Back of property (6 unit multi) usually gets hit with neighborhood trash dumpers (mattresses, couches) once or twice a year, costing me between $500-$1000/yr in cleanup fees

2) Primary goal, reduce maintenance costs.

3) Secondary goal, improve the general look for the neighborhood

4) I could spend thousands and still get hit b/c the neighborhood has built the habit of hitting my property over the years.

Question: Would you build something up here in hopes of reducing the likelihood of dumping, or just keep cap cost down and hope for the best?

(Mine is the property on the left, another owner to the right...)
