Relentless screaming ... cackling ... police sirens -- just another day in the life of Octomom's neighbors ... who all claim Nadya Suleman is constantly disrupting the community AND damaging property value.
TMZ spoke with several neighbors who all tell the same miserable tale ... everyday is like living next to a horribly obnoxious amusement park.
In fact, TMZ obtained an
that one neighbor recorded during an especially awful screaming session at Octo's pad.
One person told us, "We continuously hear kids screaming and crying and fighting."
Another neighbor told us they're constantly being woken up at 6AM by the sounds of screaming children ... when Octo lets the kids go outside to "play" with no regard for the noise.
As for the cops, we're told the constant police presence is becoming a nuisance ... in fact, neighborhood locals -- even children -- are often subjected to ID checks simply to gain access to streets around Octo's home.
But perhaps the most significant complaint -- neighbors have been informed by real estate agents that living near Octo could LOWER the value of their homes ... because they would have to disclose the fact that she lives close by.
