The HELOC may or may not disappear, but it will likely be "extinguished" from the property title after auction.After a first mortgage lender forecloses and it's lien is paid off with the proceeds from the sale, any surplus funds from the foreclosure sale are distributed to creditors holding junior liens, like a second mortgage lender or judgment creditor.And by the way, YES you should serve notices prior to entry just to be safe.After you acquire the property, what is the goal?

I got helped of a good amount of start up funds to get started... which gave me insight on a target month to start. 

Quote from @Debra Webb: I’m reaching out for some guidance on securing funding for my next real estate venture I don't have any capital to start with.

Then using the recoup to fund my primary residence BRRRR to then fund my transition into SFR BRRRR.
