<prompt> Human: So my father is looking to offer me and my wife a personal loan of 100k at 3 interest. This is with two goals in mind for him.First, hes about 10 years from retirement and wants to move his retirement savings from stocksbonds to something he can view as more secure. Hes looking at Bonds, but says theyre tending to barely above 3 ROI before the manager fees. Second, it would be a down payment for a house for us. Were golden in the income range, but we just barely got married in April and weve paid off 18k of her higher interest student loans 9.75 so we have nothing in a down payment. Houses where we would like are in the 350-400k range, our combined income is 160k and with no kids in the future to stretch budgets. Were a very safe bet as far as affordability so were not a risk to my parents. We were originally planning to take a year or two to save up a down payment, but with 3 interest its really interesting and hard to say no to. I know the general rule is no money loans to family members. I also know wed get some sort of hard contract agreement before anything is done. The loan would be between 10-15 years.My question is in relations to taxes and mortgage. How do these work with the mortgage? Is it simply considered debt to be listed in the application or is there more? What are the tax implications between borrower and borrowed? Are there any good as in rock solid excel templates that could be used for the interest accrual and payment?  <response>: A mortgage lender typically will not let you use another loan as a down payment.
