A 15-year loan is usually made at a lower interest rate. Equity is built faster because early payments pay more principal. In a 30-year loan, more interest is paid off than principal for the first 23 years, meaning larger tax deductions. As inflation and costs of living increase, mortgage payments become a smaller part of overall expenses.
Keep a mound of modeling clay handy to your soldering equipment. You can use it to hold small pieces at odd angles to each other. Push the ends of the items into the clay and position them so they meet each other. The modeling clay will hold the pieces securely and eliminate any metal contact from a vise that can conduct heat away from the work.
