Don’t know, as someone building one, I’ll let you know just as soon as I manage to secure us a place to live under seemingly bloody impossible circumstances.
@aral possibly irrelevant but when I was a new immigrant without much credit history I was able to get a mortgage with one of the smaller non-bank lenders paying an extra 2.5% interest, then switch loans 9 months later to a normal bank once I had some payment history. Good luck man.
