It really depends what your goals are. Also, there's a few things I'm not really sure about. Do you have $66k specifically saved as a 20% down payment for a $330k home? This may be an issue because you will need to show the bank reserves and may need to cover closing costs and moving costs. Are you already preapproved for that amount? I always think it is most important to get preapproved and have a lender with your info ready to go, in case you find a deal and need to move quickly. And what is your current mortgage and rent? The AV was definitely hit HARD the last recession, but most recessions are not that bad. There is also strong demand, as many people are priced out of Los Angeles. If you pull money out of your home, do you feel confident it will cash flow, or at least carry itself if rents fall 20%? Rents sometimes rise during recessions, but I try to plan for the worst. Personally, I am choosing to keep enough equity in my properties so if I need to sell I won't feel trapped or need to write a check. However, if I came across an amazing deal that I could not afford, then I would absolutely pull money out. Fortunately, I'm making decent money to where we are able to buy rentals at a pace that feels good for me and the goals for my family. So, in a nutshell if your new mortgage will make your rental CF negative or too tight if we see a dip in rents, do not get a heloc. But if you get the heloc and it still CF well, I would get the heloc. Also, if you think prices will dip, it would be best to make your credit pristine and stack cash. Lending tightens during recessions, but banks always lend.
