A few un-positive 'reviews' about LATE night partying, calls to police for legimate 'noise & disorderly' issues for those households addresses, calls to inspection offices for OVER OCCUPANCY (video of your adjoining property might be eye opening), a collection of 'fees' collected by other local (out of state) governments (income ideas to your money hungry elected officials), etc.
You are unhappy but the unhappy, angry public at ELECTED employees with benefits (retired pensions, etc) seems to effect them MORE than they like to "talk" about.
AND post your videos on the local Facebook pages for promoting your town and chat sites. We have a "Patch" FB page for our town.
Any property NOT in a zone for (short term) rentals ... and/or not inspected with properly PAID license fees, gets court appearances and FINES. Spend a day in municipal court for any owner (with a lawyer) will humble them .... along with time lost in their life, the lawyer's fee and then the FINE they have to pay. And if you neighbors ban together as a community group on FB .... more influence to curb the idiots and educate the government people into FINEs, licenses & inspection fees.
My local governments collect $100+ dollars a year for each rental unit as "landlord license", $50 for each CCO inspection for tenant turnover, fire inspection yearly, plus MORE inspection & license fees for building with 3+ rental units from the STATE office, etc.
