60% Downpayment on house?
Voluntarily assuming a loan is a bad idea, especially for a non-investment purpose. It would be one thing to take on a loan to operate a business or buy a piece of capital equipment, like a machine that would make you money. Borrowing money to have a more luxurious house is foolish. The smart move is to buy a good quality home that will meet your needs for as little as possible. Having $800,000 leaves a quit a bit of leeway in that department. You don't say where you live, but if this occurred in my area (eastern Massachusetts) I would buy a house for $500,000 and then invest the remaining $300,000. If I lived in the California bay area, it might be necessary to spend the whole $800,000. Either way there should be no need to borrow money. Also, if you buy a house for cash, often you can get a substantially better deal than if you have to involve a bank. Not owing anyone money is a huge psychological advantage in business and in life in general. View being debt-free as a springboard to success and happiness.
