I do lots of this (sell houses in Israel). Most of my non-Israeli clients usually pay the full price in cash, no financing in Israel, and usually refinanced some property in the USA, where terms are way better for them.
Those that did take mortgages needed to put down 50%. I never yet had a closing in Israel for a foreigner where the bank paid me more than 50%.
Now that I think about it, I never sold to an Oleh, so that may be different.
Israelis have some great mortgage products, low rates & fees, but underwriting is very strict. And almost all loans are "Tzamud LaMadad", meaning variable, but not terribly so.
