Two loans on one home?

[James W.]

Hi,

We all know homes at auctions many times have more than one mortgage. 

Can someone explain to me how does an owner get two mortgages on the same house?

I can imagine the HELOC. But Is there any other way how the owner landed up in two loans?

For example can owner take two mortgages at the time of financing a home purchase?

Or, taking a second mortgage a few years later, like refinancing, but paying only part of the first, so carrying two mortgages?
