If you get sold your house at the worth of 750K after 5 years then I can say you got your money whatever you paid on this house. If you don’t get sell this house with the worth of 750K after 5 years.
May be my math is bit wrong. If you buy home 600K worth now and you took 417K as mortgage then at the rate of 4.5% even as mortgage(kind of impossible of all ), then at the end of 5 years if you can able to sell your house at least 775K(keep 6% broker charges at the time of selling) then only you are squared up. Which means you will be getting cash to your hand what you pay towards till time on housing. In case of renting also you never get back but at least you don’t pay this much big bucks on everymonth and no chance of risky liability there. “Cash is King” these times perhaps
