Check with your carrier.

I would recommend getting quotes from carriers that include earthquake coverage in the property policy and it may well be less than your current policy + monoline quake. 

The issue with this is that as you grow, you will likely reach a threshold where that particular carrier doesn't want to insure any more of your rental properties. 

One obstacle is that B2R sometimes requires a carrier to be AM Best "A" Rated.

You can talk to mail carriers and have them work for you by offering a finder's fee if you close on a deal they helped with.

And only one person asked me this question : Pavel, I don't need to know how much you make, I want to know how much you could save and back then I was only able to save $200-$300/month.I don't care how much top 1% makes if they spend it all, file foreclosures and become bankrupt after their ''Hollywood or Sport carrier is over''.

My primary residential insurance policy will not cover it because our rentals are out of state, all the major carriers will not provide it either unless we move all of our primary household and auto insurance to them and a couple of companies are only willing if we purchase building coverage through them then they will add on the umbrella.

And because the postcard is general, it would not exactly alert the mail carrier of their current financial conundrum, that they may (or may not "wink wink") be dealing with.

Your insurance carrier is supposed to report to your lender any changes in the policy (the lender is a "named insured" on your policy)It's not difficult to change over your insurance.

These internal teams are able to leverage not only their expertise, but also relationships in attracting wireless carriers.
