Yes why not, in the general case. With an exception when the loan funds are being reinvested in the property itself. But in the general case where home equity from appreciation is being turned into cash that's then used for other purposes, that looks an awful lot like realizing a gain to me.

In fact this might even be advantageous to certain homeowners who live in a property as their primary residence and then convert it to wholly rental use. Before you move out, take a loan to easily realize of 250k/500k gains which you can then deduct before it's no longer your primary residence.
