oh yes bp is the best safety net for learning rather get as many dunb questions off of my chest then run into a situation latter😃

I like to buy single family homes in Detroit I can easily understand a street or block (as far as safety, culture, demographics) better than I can for multi-family in Detroit.

If they weren't aware or address major issues like leaks, hazards, etc. that's when I'd be worried about their ability to manage.In regards to being billed months late normally they won't charge you until their charged by contractor/landscaper, and just know their probably using joe blows landscaping who knows how to haul around a mower but probably not the most attentive to administrative/billing of their own business.

What are some of the hazards that should be considered?

In six short months, I have taken my savings from a mere couple hundred to now within a few hundred of a fully funded "safety net." 

A service dog is much, much different than an emotional support animal.Tenantresourcecenter: "Landlords can only deny the service animal or emotional support animal if: the tenant is not disabled or does not have a disability-related needthe tenant fails to provide requested documentation allowed by this lawthere is undue financial or administrative burden or would fundamentally change the services providedthe specific animal “poses a direct threat to a person's health or safety” that cannot be reduced or eliminated by another accommodationthe specific animal would cause substantial physical damage to the property that can’t be reduced or eliminated by another accommodation.

At what point do I call the police if there's a legitimate worry regarding their safety or the safety of their two kids?

Any hazardous trees, or too close to the house?  

That doesn't give you much margin of safety.

Day Care businesses may require additional fire/safety upgrades to meet code.
