• Outstanding mortgage $50 000 (15 years left, 3.5% interest rate, monthly payment $360)
• No other debts. Income $120k a year, spending around $30k of that.
• $90k in the bank account
Take $90K from the bank and pay off mortgage($50k) immediately tomorrow. Come back and thank me :) for sleeping better at night!
I sleep better at night knowing I've got a large sum of liquid investments. Having a mortgage doesn't bother me. I wouldn't encourage others to have an emotional reaction to what should be a financial decision.
Here's an "middle-view" plan that's optimized to minimize your taxes while still allowing you to pay off the mortgage in one lump sum in approximately one year. This plan assumes a self-employed income of $120,000 per year, a family of 4, and only one spouse earning income:
-Open a solo 401k. You can contribute $19,000 pre-tax for your individual contribution, plus $24,000 for profit-sharing (20% of your net $120,000 self-employed income).
-Open IRAs for you and your spouse. You can contribute $6,000, plus your spouse can contribute $6,000.
-Based on the above, your total available tax-advantaged space is $55,000. By using this space, you reduce your federal income tax to $0. (You'll still pay self-employment tax, but aside from that your federal tax liability would be $0.)
-Putting $55,000 of your $90,000 savings into tax advantaged accounts leaves you $35,000 to put into an earmarked savings account for mortgage payoff.
-Assuming you spend $30,000 per year, then after maxing out your tax-advantaged accounts you'll have just over $1,200 per month to add to your earmarked mortgage-payoff savings account.
-So in about 12 months, your earmarked savings will have increased to $50,000. Then you can pay off your mortgage in one lump sum, without sacrificing any tax savings.
ETA: In reality you could pay off your mortgage faster than 12 months, assuming a steady income stream. If you immediately earmark $55,000 into tax advantaged accounts, then all future 2019 monthly surplus can go straight into your earmarked mortgage payoff savings account. You might even be ready to pay off the mortgage in one lump sum by the end of the year while still optimizing your taxes for 2019.
