Before I go into more depth, I don't actually believe Alex has ever lived in this house, and is just a house he stayed at for some New Years parties with family.
You were way closer then you think you were.

Matching up streetview with videos he's taken. The house directly to the right of the first image is 936 Langholm Dr SE.

Reminder, he has most likely never actually lived here. This is probably a family's place he stayed at for New Years. I am currently working on finding the address of where he used to live.
Good going on the doxx. I thought he was living in australia because several of his older videos were filmed over there.
There's this weird neighbourhood with that swimming pool and a hut where he was living in at some point.
I was trying to find out where it is via the overhead view on google maps, but Perth is immense AF and there's no faster way that I know of to find swimming pools or huts via Google maps or any alternative.

I have nothing better to do this Sunday, so for the next 12 hours I'll keep trying to find out where this place is and whether it is a residential area or it is a resort area (I lean towards the latter)
I was trying to map out the whole travel path he took and I successfully identified on which road he was driving and the speed signs 100% confirm it's australia, if it was Canada or America there would be no red circle surrounding the numbers.
Also notice the palmtrees like in that other vid posted by Toji, this must be near where he was taking a nice vacation.
Each avenue also match perfectly with
Currambine both in name and in the order they show up, the only thing that doesn't match up is the lack of a roundabout in the video, aldoebeit there was a sign signaling there was going to be a roundabout, but he never drove on it in the vid, so he was probably driving on an offroad or smthg.

Also, before he was KermisVoyager1997, he was
Markiplier SUCKS, VanossGaming SUCKS and PewDiePie SUCKS [OFFICIAL]. I think he might have been associated with UTTP back when it was an unfunny trolling group as opposed to an "ironic" pedophile group. Most of the videos uploaded during this time are unlisted, but they are likely archived
here.
I knew the high pitched voice on some of the vids was giving off some deja-vu. I know who these guys were and yes they were all part of the same clique of youtube trolls. There was also Super Nintendo Boy, a Super Minecraft Kid ripoff and that's how I remember finding that Mariotard SJW lolcow who also didn't like those guys, but didn't like me either.
Not getting into the details, but he made a video on Super Nintendo Boy and Markiplier Sucks trying to change the pitch of their voices via Audacity probs in an effort to find out what they really sound like. I don't remember exactly his username anymore, but it was something like SuperstarMario and there were numbers right after his name.
