Upping your HELOC with funds drawn

[Sean Harris]

My wife and I have a HELOC that I will be using to pay for some of the down payment on a house. We got the HELOC about 3 years ago and since then the value of our home has gone up quite a bit. So my question is can I ask the current lender if I can have the house revaluated and get access to more money in the HELOC or will it have to be paid completely down before I attempt this? Thanks
