There is no way you can interpret your numbers with any consistent accuracy. 

This is an interpretation, and not something explicitly outlined in the tax code. 

(c) Prohibited transaction(1) General ruleFor purposes of this section, the term “prohibited transaction” means any direct or indirect—(A) sale or exchange, or leasing, of any property between a plan and a disqualified person;(B) lending of money or other extension of credit between a plan and a disqualified person;(C) furnishing of goods, services, or facilities between a plan and a disqualified person;(D) transfer to, or use by or for the benefit of, a disqualified person of the income or assets of a plan;(E) act by a disqualified person who is a fiduciary whereby he deals with the income or assets of a plan in his own interest or for his own account; or(F) receipt of any consideration for his own personal account by any disqualified person who is a fiduciary from any party dealing with the plan in connection with a transaction involving the income or assets of the plan.Purely my opinion here, but the between interpretation would seem to make sense as the proper intent of the code. 

Don’t get me wrong, when the law is grey, my job is to advocate for the best interpretation for my client.

Data entry into the MLS isn't always entirely accurate so you can find deals where for example a property has been overlooked for many months and is interpreted as "overpriced" by everyone that assumes the property is where the MLS indicates on it's map. 

I would be very careful about interpreting data, especially with real estate. 

Home run deals only and everybody has their own interpretation of a home run deal.

It's also up to interpretation so I'm sure you can find good representation if needed. 

How the legislation and regulations are written and interpreted will be a big factor in whether it is worth your while to accept pets.Here in NB, we are allowed to discriminate and not allow pets, but other jurisdictions (ON) that appears to no longer be the case.    

But it could be up to the interpretation of your lender/underwriter.
