Fortunately this regulation expired last month. 

I've researched the subject online but I don't see very much information regarding rules and regulations on renting to tenants with pets, I have a few questions:What are the limitations on size of pets?

I'm in Canada in case that makes a difference with the regulations or laws.Thank you,Yves

But practically, no need to sign any leases now as long as you both agree.

We just found about it and I am little frustrated because now I have to coordinate times with the tenants.Is this a common practice for refinancing?

I’m currently studying and practicing analyzing deals.

Appraisal demand is quite high at this moment, and rush fees and higher fees for more rural areas are common practice.   

I don't see any reason why the Landlord should be responsible for health practices of their tenants, but you need to decide for yourself how you want to operate your business.Check out Stessa.

@Chris Mason You must have practiced that one, your analogy is impeccable!

It's high risk due to regulations and landlords changing at a whim, and it's high effort for minimal payoff.
