Can you still use heloc for down payment on investment property?

[Amber Smith]

hi! Im in southern ca & i know this question has been asked several times in the past but I wanted to ask if anyone in the Last 6 months has used heloc money from their primary residence as the cash needed for 20% down on a multi unit investment property? My mom was a lender up until she retired last October and she told me today that you used to be able to use heloc money for down payment, but that the rules have changed and now that money has to be in your bank account for 2 months (bc that's how far back the underwriter looks at). I have the equity in my PR, I can afford the heloc payment & easily still get cash flow on the multi unit, all I'm Wondering is if anyone has done exactly this in the last 6 months & if so, how long did the heloc $ need to be in your bank.
