I will say, as a programmer, I built my own system that was comparable (better in some ways, not so much in others) in many ways to Dan's, but I didn't have online access to the Upset Bid sheets and that was a significant factor in my using his service.

Is this someone who is knowledgeable in Landlord Tenancy Act or someone knowledgeable about the legalities involved with purchasing property?

Owner of a property in each city and now focused on investment opportunities with upside (renovations, change of use, working thru legal issues, etc.). 

Do not rely on it for legal advice.

Will the property type need to be changed legally?
