I struggle with this simple math problem. Others on BITOG will not- but I do.
Eight months ago, Wife and I purchased a home. The home had an assumable solar loan, original balance of $50k USD, we assumed the balance of $48k USD, 1.99 percent interest, for 30 years ($212 monthly payment). The original purchaser of the solar likely overpaid, and the solar parts and labor should have been in the $15-20k USD. It appears the purchaser of the solar received a check from U.S. taxpayers for $15k USD, solar rebate. The original purchaser of the solar likely went for the deal, as their electric bills were about $200 USD monthly. So, install solar, reduce your electric bill from $200 to $12 per month, and get a check in the mail courtesy of U.S. taxpayers for $15k.
So, here is my dilemma. Pay off a $48k loan, on a solar system that new should have cost no more than $20k USD? I have the money set aside to pay off the loan at any time (currently earning four percent at a NCUA insured financial institution). I am very tempted to pay the loan off. Or keep making payments, for 28 more years, where the total interest over 28 years will likely be in the high five figures.
I know the expert/ savvy/ smart money method is to keep the money in the bank, make four percent interest, and keep making the payment. But I am not so smart and hate paying potentially a high five figures in interest.
Caveman GON here.
