In your calcs, you can factor out payments, because I didn’t have any as the house was paid for in cash.
Then you have to factor in a conservative 3.5% interest from a CD of 2.0M dollars over that term. That happens to be about $5800 a month in interest, or $208,000 over three years.
I would also say that it’s always going to be difficult coming out ahead when you own the house outright versus renting. Or if you pay for the house in cash versus the cost in renting.
