Well a 400k house is probably going to be worth 2.5-3 million if not more in 50 years.
And 2.5-3 million will have significantly less purchase power than it does today. I'm not sure if that's worth it considering you're gonna pay at least double the amount of your loan in interest alone over 50 years. So over 50 years you'll have made a 'profit' of 1-2 million if you sell your house and then you'll be without a roof over your head at age 70. Sounds like a pretty shitty investment.
