$5100 for $1M borrowed (a low) 3%, excluding down payment, property taxes, and likely PMI, given how onerous saving 20% of seven figures is.
If you negotiate with a couple of banks in Sweden you can easily get sub 1% (0.79% is what I seem to be able to get). Heck I just checked my bank and I can even get a line of credit up to 1M SEK at 1.74% for up to 50% of my portfolio without any property as security.
