re: Selling stock to buy foreclosure

If you have enough invested assets borrowing against a Pledged Asset Line may be a better option than HELOC. I wouldn't sell stock and realize the tax hit until aftwe the winning bid goes through which might be too late unless you have other cash lined up to finalize sale. My county requires 5% deposit for auction (forfeited if you win but don't come through w full payment) and balance is due next day.

If you dont wind up renting or flipping the house it just sounds like an expensive alternative to renting a storage facility and potential maintenance liability. Hope you don't get squatters in a vacant home just used for storage.
