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.

Anything left to interpretation will end up in court and then how will the courts decide ?

@YiBing T.What you are proposing is possible based on the interpretation of many tax attorneys, as outlined by @ George, but there is still some layer of risk if there is any perceived benefit between any of those plans.

Knowing how to read and interpret a contract is a valuable skill. 

If the law says 30 day notice, don't file until day 31 or better 32 just in case a judge interprets they way you did it differently than you.
