I found Escrow.com's instalments payments mechanisms very cumbersome, so much so that we eventually just paid the balance out.
The fact that Escrow can't arrange a direct debit, that the transfer is at risk every month that an instalment is due, that each instalment has to be separately invoiced/paid, often leading to minor fx discrepancies are all factors that would discourage a potential buyer from proceeding down this path.
