That doesn't sound right to me. I purchased my home about 3 years ago and if I remember correctly on top of principal I would end up paying an extra 40 percent or so in interest. To pay 2 million on a half million dollar loan your interest rate would have to be insanely high (like 30+ percent). In my case my mortgage was only about $300 more than the apartment I was living in previously (very expensive area) so it would've taken an extremely long time to save up the cash to purchase our home. The house has also appreciated nearly 50% since I purchased it, so if I had waited it would have been too expensive for my budget
