HELOC Appraisal — where do they get values for virtual appraisal?

[Allie Dattilio]

In the process of applying for HELOC, bank uses a virtual appraisal. We can then pay for a full walk through appraisal if we're not satisfied.

But looking to understand what values/comps they use for a virtual appraisal to be able to anticipate their numbers. Can anyone point me in the right direction?

Assuming they don’t use Zillow. 😏🙃
