Same here.
Bought it off my landlord after renting it for a few years. Been a good investment, and I was able to tap it during some rough times. Currently on a 6 percent fixed.
To be fair, most buyers don't have a lot of choice on where their mortgage ends up nowadays, or what government mortgage organization gets involved down the line.
In the old days, your mortgage holder was the bank or S&L you got the mortgage from, and it stayed that way for the most part. Nowadays, the mortgage can be sold off to another holder without so much as a by-your-leave. One of my equity lines got flipped about a week after I signed it. Doesn't actually affect me, of course--all the terms stay the same--but it's annoying in some ways.
