I did it for 6 months for a very specific reason - one dc was being bullied and the child doing the bullying was the offspring of a teacher in the school. I was not happy with the way it was handled, no other school readily available that I wanted to send them to. My youngest dc had just started in reception in the same school and was miserable, really really miserable. I had been a teacher so thought I would give it a go, I joined Education Otherwise and the Home Ed network and read up on everything I could get my hands on (of course it's all online these days!). Middle dc was happy in school so wanted to stay there - but soon decided that they wanted to join us.
I was very very impressed with some of the other HE parents, less impressed with others - but none of the kids I came across were in any way 'feral'.
We did eventually get the dc into a school where they were happy and I was quite relieved in the end as it was very full on. I think if it had been any one of mine we might have continued on with HE, but all three was tough as they were all so different. I had one making me timetables and complaining when I didn't follow it "she should be doing maths now, not reading!" along with an anarchist who resisted all attempts to follow a curriculum
.
Many years later I did some tutoring for a neighbour who took her ds out of school because he was being bullied (start of secondary school) causing bed wetting and severe anxiety. Again the school (different one) did not handle it well. He stayed out of school until the start of GCSEs and then went back in when he was ready and did OK academically. He was a bit of a geek anyway (which was why he was being bullied) so was very easy to teach as he was so interested in stuff.
HE can be a very different model to school - you have concentrated one to one and the actual teaching bit can be much more efficient. there is a great HE community in most towns where you can get help, join groups, access sport, art etc.
I work in education and all the research I have seen shows good outcomes for children who are HE - leaving aside the nutters who restrict the curriculum who don't need to do that now they just send them to a Free School
Join up with other HE parents would be my advice, do it for as long as it works for you, you may only need to do it long enough to get your dc through a rough patch as I did, or you might find it's the best way for your dc to progress. Good luck!
