It wasn’t wrong, it was just another strategy.
The thing about a HELOC is that once you have it, you can do whatever you want with the cash. You can cash out to buy 100 pairs of designer shoes if you wanted (but gosh please don’t).
The HELOC qualification process is just like a mortgage. They’ll underwrite the loan, get an appraisal on the property, and then tell you the amount of the HELOC for which you’re eligible. Once it closes, you can access the cash at any time for any reason.
I have a HELOC on my primary residence and since I got it through the bank I use for my personal checking/savings accounts, I paid no closing costs. Then the HELOC line shows up when I log into my bank, and I can transfer cash from the HELOC to my checking account and use the funds immediately. The interest rate was also pretty low — 2.99% the first year, 4.99% after that.
In other words, as long as you still qualify for the HELOC, you can still get it now — and you could even use it to acquire ANOTHER property if you wanted! (But do bear in mind, you’ll have another “mortgage” payment due on any funds you use from the HELOC.)
Some lenders don’t want cash for down payments to come from HELOC funds, but some are ok with it. I went through this last year — I applied with 3 lenders, all with similar interest rates, but I went with the one that let me pull some of my down payment out of my HELOC because it was easier than liquidating a couple of mutual funds I had. (I’m glad I didn’t liquidate them too, because they’ve continued to increase in value).
