2 houses 450k each or one 800k?
Forget the math's specifics for a moment: here's some principles. Additional housing for a renter gives you returns in the form of money. Additional housing for yourself pays its returns in the form of "here is a nice house, live in it". Which do you need more of?  If you don't need the money, get a nicer house for yourself. If you need (or want) the money, get a modest house for yourself and either use the other house as a rental property, or invest the proceeds of its sale in the stock market. But under normal circumstances (++) don't expect that buying more house for yourself is a good way to increase how much money you have. It's not. (++ the exception being during situations where land/housing value rises quickly, and when that rise is not part of a housing bubble which later collapses. Generally long-term housing values tend to be relatively stable; the real returns are from the rent, or what economists call imputed rent when you're occupying it yourself.)
