Use a line of credit from a vacation home to buy a primary residence?

[Calvin Matthews]

Hello. My wife and I own a vacation home in Texas and are renting in our primary residence. We'd like to move out of this primary residence and initially were looking for a new place to rent, but then I remembered about line of credit and then had the idea to inquire about this for our vacation home. We've never applied for a line of credit but I'm wondering if it's feasible to do, especially for a place that we want to reside in rather than a place that we want to rent out. I tried searching in the forums for a similar post but came up empty handed so I welcome facts and opinions from everyone. Thanks in advance.
