If asked, we recommend 15 years with 20 years being okay but not preferred.
We point out that:
The maximum plan loan is $50,000 and the mortgage amount typically is considerably higher. The plan loan often helps spread paying off realtor fees, closing costs and moving expenses.
A $50,000 loan will have monthly repayment of about $400 for 15 years or $330 for 20 years. Most loans for purchase of a primary residence are considerably lower since the individuals taking the loan commonly do not have a vested balance that exceeds $100,000. For a $10,000 loan, the monthly repayments are about $80 for 15 years or $66 for 20 years. These are small amounts (and even smaller when the payroll period is semimonthly or biweekly). Processing loan repayments for small amounts can become an annoyance for payroll.
The longer the loan amortization, the more the participant and/or employer likely will pay in loan administration fees.
The longer the loan is outstanding, the more likely the participant will terminate with an outstanding loan balance which always seems to add time to process the distribution.
