Vancouver, B.C. Financing possibilities to avoid speculation tax

[C.Y. Li]

How to title this post but this question is probably pretty specific to Vancouver, B.C. where they had implemented the speculation tax. For those familiar with the tax you'll probably understand where my pain is.  My parents are living in a home that I own with them and because I do not live in Canada currently, I'm subject to this speculation tax. Was wondering if there's a way I can become the bank and lend them money like a home equity mortgage, where I have the lien in the deed for lending them the money and not have my name on title. Wanted to know what are the implications, how this works in terms of process. I will be speaking with a real estate lawyer but wanted to make sure I know the process and kind of know what I should ask rather than going in blind. 

I know I'm very brief in the question but that's because I really don't know what information is relevant to provide. Thank you in advance for any advice.
