Looking for a Heloc for around 500k

[Namit Raisurana]

Hello, 

I am looking for a Heloc on my primary home for about 500k. I am based out of California. 1st United services credit union offers heloc for 250k without any cost, but for 250k-500k I need to pay for closing cost and appraisal, costing me around $3500. 

Any suggestions for better HELOC? Any gotchas I got to keep in mind? I will mostly use these funds to make other investments, but dont have that decided yet. But want to have the funds ready so that I can jump on it when I find a good opportunity

thanks in advance
