Things like Knob & Tube or Aluminum wiring, in ground tanks, tenants with certain breeds of dogs, proximity to a coast, etc. are all factors that could limit the companies that will insure you or raise the cost.Feel free to PM me if you need more info on any of this. 

Without my knowledge and consent, the tenant brought in a pit bull (or similar breed).

What breeds?

(such folks are called syndicators... the highest breed of individuals who are pretty much very smart.. and know if deal makes sense or doesn't... these are the folks that are also connected with other people...... these are the folks who you want to also get in touch with and stay connected.... )  Note however.. that sometimes... relying on other folks to be the ones to give you money... just for you having your boots on the ground.... indeed can be very difficult journey... but believe me there are passionate folks out there who like to analyze deals, but do not have trustworthy individuals with boots on the ground... and looking for some sort of mutual relationship in their journey towards financial freedom..You see... it's all about the value that you provide... to others.. and reasoning as to why they should be associated with you...

@Tim BartelFrom my experience with pets, it seems that dogs mature at different rates depending on breeds.

Just think it’s two different strategies for different breed of investors and you need to identify which best suits you.

If there are a lot of tenants searching for rentals that allow pets, it is best to cater to them with whatever limitations seem fair (pet age, breed restrictions, size, etc). 

S8 is high risk, not due to payment so much as opposed to damage/abuse to property, violation of the lease, restricted breeds of dogs, bringing in unregistered tenants etc.

I think you have to own one or two to understand the breed.
