That's right, the financed amount is the same as the cash amount. It is indeed a sweet deal, especially after todays CPI release. They are cutting into their margins for sure. Only wish they would let me take out a 30yr loan instead of 10yrIMO, if the interest rate is that low, make sure they're not baking finance charges in. Someone has to prop up rates out that low. The 10 yr treasury rate may be low, but it's still north of 100bps. I don't see Tesla giving up more precious margin for free since they're already operating at what seems like a loss on the solar-side.
Also, try to have capital still to pay off the loan balance if you ever try to sell or refinance your house. These solar loans and wacky liens on fixtures can be a big headache.
And yes, have the cash to pay off if needed. Or could always sell my now gently-used MY SR (bought at $39,990) for a profit, I've seen listings for >56k!
Strange that a refinance would require the solar to be paid for? Even if one has <50% LTV?
