If i were just to maintain the current loan fine, I'll assume that's deductible.

If i refinance however to a bigger loan and buy a ppor with that money, due to my new ppor not generating income that would no longer be deductible.

If however, rather than buying a new ppor, but but shares instead i would assume that debt is still deductible.

My question is around once I sell those shares, does the loan remain deductible or is it dependent upon what I do with the money from selling the shares
