Should I set a policy with a standard fee and rent scale per type of animal or is it acceptable to change based on the situation?

As for the Landlord 101 class, it looks like you'll need to complete that as well for your Fire Certificate of Occupancy: https://www.stpaul.gov/departments/safety-inspecti...Depending on the grade you received during your inspection, your property could be inspected every 6 years, or potentially every year if it's really rough.TL;DR- City of St Paul doesn't have a landlord license.

I ask the landlord to rate them as a pet owner on a scale of 1-10. 1 being someone that totally neglects the pet and 10 being the dog or cat whisper.

But for firms that manage 1000+ units, it seems there may be enough scale to make that an organized business with systems, processes, and employees.  

For larger projects this may be more as pre-development costs for a project of this scale can be intensive. 

Scale, hardwater, well water with sand in it, debris from flushing hot water tanks, debris from dip tube failures in the hot water heater, all play havoc with all modern fixtures. 

They are about 3 school grades apart, so there could be something like a 7 year period where at least one of them would live in a rental property that I buy and rent to them.  

This rule, and any other rule that involves the same grading you use for milk, has nothing to do with reality...just gena"reality".

Laminate floor durability is rated on a AC scale 1-5. 1being least durable, 5 most durable. 1-3 is considered residential, 4 and 5 are considered commercial.

It must be the CPVC grade stuff.
