I have a four plex with a balloon loan that is soon to be due and I have the option to do another balloon loan but I am thinking about refinancing all of my properties together.I am looking to get away from traditional personal mortgages (which my two duplexes are on) and also cash refi my SFH that is owned outright and get them under one loan under my LLC. 

Can you get in there to take a video?
