A mortgage for a $1M property is roughly $4-$5k depending on credit etc etc.
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.
