I don't want to sound harsh, because you will get a lot of good
ideas here, but your dilmemna is not an unschooling one, it's a
school one.

"We will not be able to afford our new
house. "

I would seriously never buy a house that would force me to work. I
love the peace I have in knowing that I could quit my job at any
time and we would be fine. It doesn't leave you much flexibility in
the homeschooling options department if you MUST work, unless you
can find different work that gives you some new options.
Is it too late?
Can you buy a different house?
Or stay put?
My child's peace, safety and love of learning are FAR more important
than having a bigger or better house. Only you know the answer to
this one though.

My first thought was to let your child quit school and be with you
at work. Is there a lounge or area he could be for part of the day
and then maybe spend the other part with your dh?
Can you find different work? Or work from home?
Of course you CAN, what I mean is, would you be willing to look at
those options?:)

If you really want to get your child free of the system, then it's
going to take a big shift in lifestyle it sounds like. There isn't
that much left of this school year, if you could just take him with
you to work, it's only a few more months.
If the house is the only thing standing between your child and
peace, I think it's time to re-think priorities. That's just me
though.
