The entire property & casualty market is a mess at the moment with carriers being unprofitable across the board and many becoming insolvent or shutting down in states where they were least profitable and/or were not allowed to take the rate increases they were asking for (rate increases have to be approved by each states dept of insurance they don't just get to jack the rates up because they want to)If you are in a REIA reach out to some of the players there and see who they recommend.

Your HOI needs to be able to insure the LLC, not additional insured(some carriers do this), and I recommend getting commercial umbrella insurance for your LLC especially as you get more and more properties.Also, personal umbrella insurance coverage for yourself.

@Jimmy Hung if you can find an insurance carrier to offer Agreed Value, you can insure for a lower limit without being penalized for underinsuring. 

Another thing you can do when you receive one of these texts is immediately report them as spam to your cellular carrier. 

Both are very well versed with investment properties and can shop multiple carriers for you. 

Long story short I was at least able to defend myself, invoke the general warranty in my deed, add a claim against the attorney for malpractice... and the malpractice carrier paid the item days prior to the scheduled foreclosure.To those who like to gamble and as I say to all buyers who decline owners coverage...

Which carriers have you tired?

I'm a fan of Erie for P&C but more important than carrier selection please find an agent that can represent you and build a relationship with them.  

Yes, you should contact your insurance carrier and change to a landlord policy. 

Then I own in a semi-franchise model,  basically own the trucks and buy routes and employ drivers to fulfill the logistics; you can contract with fedex, amazon, any shipping carrier, and get a ton of business quick.
