What would you do ? (Neighbor problems)

Hello everyone! We’ve recently moved into a new home and we rent out the main floor. There’s a 4 person family upstairs (two adults and two children under 5) and there’s a family downstairs renting out the basement (a couple and a 7 year old boy.) We are a family of 4 (two adults and 2 kids under 3).

This house was abandoned, but a real estate agent brought it into living conditions, and my husband and I fixed it up to look more visually beautiful. The neighbors upstairs are seriously, so kind. We all moved into this home at the same time and have really gotten along with everyone (until recently). The family upstairs joins my husband if they see him cleaning up outside or even joins us if we’re just hanging out watching the stars. I want to point out that, we’ve wanted peace with all our neighbors bc that’s the best way to live out renting this home. We don’t see the downstairs family as much but we make sure to show our love when we do see them!

Unfortunately, things downstairs very quickly became violent. The husband from downstairs had mentioned to my husband that “the realtor had known them for years and wasn’t really wanting to rent the basement to them.” Which sounded super odd to me bc we know the realtor as well and he was super determined to rent this place out.

Fast forward, I hear screaming and I’m think there’s a movie playing. Or it’s outside maybe someone or something Idk.. but I hear it so loudly and I get the chills of how desperate and loud these screams are. They get louder and more chilling and I realize, it’s downstairs. The little boy is being beat. Not disciplined, but ABUSED. I can literally hear him being hit and her screaming and the husband (the boy’s stepfather) telling the boy to shut up. He’s being beat, is he not supposed to react in pain ? The screaming terrified me, the sounds of the hitting could be heard from up hear and it’s 3pm..

The next incident is when there’s music and it’s 3am. Super loud and I’m thinking it the neighbors BESIDE us. I paid it no kind really bc well.. whatever what can I do ? But it 4am and it doesn’t stop. It’s obnoxiously loud. Come to find out, it’s from downstairs. I texted them to please lower the volume. They respond “it’s kareoke night.” An hour later. I’m that lapse of time before they answered I called the realtor to ask them to please lower it, because the volume is just out of control. They respond that message and hour later and then say “you didn’t have to call the realtor.” It’s 4am, there’s children up here, upstairs and down where they are but ok. Next its 5am, they’re both drunk. Cursing loudly, and then they start physically fighting. NO I AM NOT AWAKE ON PURPOSE. I’m currently pregnant and need my sleep. These two begin physically fighting up the stairs and she starts crying, cursing and the fighting can be heard again. The music starts, AGAIN. It’s past 4am..

The next incident was tonight. I’m in the nursery studying, it’s 12 am. I hear some moaning and I thought it was my son dreaming? Lol Idk. It gets louder and louder and to the point where it’s a full on porn show. I couldn’t study anymore and this for me is it. I literally spoke with my husband just a few weeks before how, I enjoy our sex but if he noticed me have to muffle or anything, it’s out of respect that 1. This house is super old and everything can be heard. 2. I respect the children’s innocence, both here and downstairs and upstairs BC THE WALLS ARE SO THIN. We all rent here and we all have kids. I get it, I have sex too but I don’t do a full on porn show blowout when my son is next door or kids are upstairs. My husband and I have great, great sex but we don’t forget we rent with other people and again, there’s kids. I had enough. The child downstairs is exposed to abuse, his parents being drunk and violence and he has to listen to this. It’s not my life but that’s exactly why I don’t have to here it. I call him and let him know, it’s too much. He tells me “I can hear your footsteps from upstairs and I don’t say anything.” I responded to him with everything I said about the 2 other instances I’ve heard and then said “that doesn’t compare to normal footsteps you can hear as renters.” I never mentioned the 2 other instances to him before. The second time I just said to lower the music but never mentioned I heard them drunk and fighting. They’re not interested in taking out their own garbage, parking in THEIR AGREED parking spot (all 3 husbands made the arrangements very early on) and overall I don’t know how to go along about this. Or even if I should do anything, they claim it’s not my business and it’s not but, they’re adults, they can put excuses and whatever on their own problems but my concern overall despite this post is that child.

EDIT: To the comment saying all I care about is the noise, I believe I mentioned the children, their innonce, the child’s exposure various times in this post. Read it again and you will notice it. If the last incident is longer it’s bc it’s the only one with a conversation included along with my own commentary. I also clearly ended saying my concern overall is the child. I’ve been married for 4 years. I rented in another home for 4 years and never ever had something like this happen so close to me. That’s exactly WHY I titled, what would you do ? Asking for advice as of what I can do in this circumstance. I’ve never been in this position and if I called the realtor it’s bc the husband didn’t answer and I didn’t really know what else to do. I have children of my own and I feel for this child. That’s exactly why I’m asking for help bc again, I’ve never ever been in this situation and wanted to seek advice. I mentioned the child’s innocence and I let him know I heard it bc I WANT him to know, that we heard the abuse. If I only cared about the sex I would’ve left it there and never told him about me hearing them beat his child. I appreciate your response but I can honestly say, the noise also comes to nothing in comparison to this little boy’s life. Despite the misunderstanding, I appreciate the comment and will do EXACTLY EXACTLY that!
