<prompt> Human: Hi Reddit,My girlfriend 31F just inherited quite a large sum of money 1 million dollars! and as a result is now looking to buy a house. She has been renting for quite some time, and I am trying to figure out the cost-benefit for her between investing the money vs buying a house. Here are some details:House cost: 600kHer current rent: 2000moIf purchased, she could rent out a floor of her new house for 2000mo!Shes willing to stay in the area for at least 5-8 more yearsAssuming normal real estate growth in this area over time a close suburb of Boston, MA.While I have been able to learn several key aspects of personal finance just by browsing this reddit investments, 3 fund portfolio, interest income, etc, I dont know how to weigh this against home ownership. Basically, how can I tell her whether renting vs buying is better, or whether a SMALL vs LARGE down payment on the house or just buying it outright is the smartest decision?Thanks Reddit! Any helpful feedback would be welcome.edit: the inheritance is within a trust fund in her name - taxes paid - so I believe she will get the full 1M amount  <response>: Dont under estimate the value of simply doing nothing and thinking about the choices for awhile.There is no such thing as a 600k purchase thats too good to pass up.
