(Unless you opened the HELOC while you still lived in it.)So, you probably need to run the numbers on alternatives. 

Selling to investors at a fraction of its worth is not ideal, so I'm looking for alternative solutions.

I would definitely ask your lender for an alternative.

His company organizes structured settlement sales as an alternative to 1031. 

If one want's a safer place to play in that arena I'd suggest to follow the Oracle of Omaha and look into the transportation leg of O&G, more volume = more transport = more revenue = more profits.  100% correct, but wasn't expecting someone on an REI forum to come at energy like this.

@Ashley GuerraTo build a profitable portfolio in South Jersey, choose a single-family house (SFH) approach with closeness to schools and safer areas, or a multi-family home (MFH) strategy using FHA loans, seller financing, partnerships, or responsible leverage of family home equity.

Many alternative lenders simply do not lend on mix-use real estate or require the commercial to residential exposure to be below certain thresholds.

That is, unless investors are now willing to pay more than the 1% rule used to dictate.I know it will cost some time and money to get them vacant and fixed up, but the alternative seems to be to leave 10s of thousands of dollars on the table.

Townhomes are also a good alternative.
