<prompt> Human: First of all, I am very fortunate to be in this situation.Im 43, live in the Bay Area renting and just received a 1.5 million dollar payout Startup company was acquired. After taxes I should have around 750k.My wife and I have been looking to purchase a home for the last year in Marin with a budget of 800k - 1.1M. We have saved 300k for the downpayment and another 100k as an emergency fund with additional 401k,stocks and savings for retirement. We do not have any debt. With all of this good fortune, would it make financial sense to pay all cash for our primary home First time buyer or should we use traditional financing 20 down and invest the rest?Any feedback or suggestions would greatly be appreciated.  <response>: Im assuming you will look to work more?If so, Id probably go for a traditional 20 down mortgage and invest the rest. Mortgage rates are still very low so Id rather look to build a very strong retirement fund.
