hi there, my uncle and i were discusssing if i could buy his house. he is currently paying interest only on his mortgage of about 175k he suggested i pay an amount every month of say 300e for six years untils his retirement and then i pay the balance of a figure we agree on now which i was thinking of about 180k are there many pitfalls to this type of arrangement i never owned a house and would not get a mortgage on my own at the moment thank you
