Therefore turning the old primary that the equity line is on into an investment property.

What investing methods (buy & hold, turn-key, BRRR, flipping, etc)?

This would turn the property from an investment into a liability in the short term.

Wells Fargo is a bit unique... they get fined/penalized so much that they evidently turned their restitution payments into a formal first time homebuyer down payment assistance program.

You need to turn them into a good tenant by having them pay full market rent or you find a good tenant that will.If market rent is $1900 anything below that is charity.

They then take those notes and package them with others from similar purchases and sell them along with their analysis to private investment funds.This leaves 45 notes from a package of 1,000 that three professional investment funds, doing intensive analysis by highly trained MBAs, have determined cannot yield even a minimal investment return.These are then offered to the individual investor, who according to those in the industry “with something to sell” (the leftover NPNs and/or “training”) can profit enormously by (1) making them re-performing notes or (2) foreclosing and selling the property for large profits.The pitch from those “with something to sell” is twofold: (1) “There is plenty of meat left on the bone” (actual quote), and (2) if you send the borrower a complete package of all docs, weighing, say, five pounds you will “shock and awe” him into paying on the note.I highly doubt either of these claims have even a micron of validity.The parties with a financial interest in you buying into this will cite isolated instances of great success, never mentioning the all-more-frequent instances of total failure.So at the end of the day the training promoters have collected up to $30,000 per person for their NPN “mentoring”/”coaching” program, the retail asset disposer has made 50% to 100% profit on their inventory, private middlemen have turned a $2,500 investment in a note into $16,000, and my sister-in-law who purchased 5 NPNs over three years ago and has spent large amounts on attorneys, taxes, and brokers has yet to see a penny in return.To paraphrase, if you don’t know who the sucker is in any ultra-high profit promise situation, it’s you.

They scanned the sidewalk, backyard, and checked the basement and outside around the house for signs of oil piping.

Turn key properties just don't pencil out as good fit investments for me.

I sign on the HELOC today and all is well, other than my bank account being $700 leaner...lol. 

However, I've put about 40K into the building in the past five years and the result is a nice, updated, prior duplex turned triplex.
