Amount of income can go up based upon more cell carriers using the cell tower.

The same trick works with garbage men and postal carrier but the police are the best because the know who the real jerk tenants are.To your successJosh  

Most commercial insurers dont have the volume to have as many carriers as they have.  

If it's not recorded the best source would be the lender/note carrier.

They will want to know:- locations (need that to determine fire protection)- Age, Sq Footage, current limits- claims history- dates systems (Electric, Plumbing, Roof, Heat)- any burglar or fire alarmsthey may need- do the tenants have pets- are there in ground tanks- who the current coverage is with and when it renews- tax id for the owner (FEIN for corp/LLC or SS # for individual)With that info, it may be a quick answer as to whether or not your current carrier is competitive or they  may need to rate it up.

We will have to approach a few Surplus Lines Carriers but let me give it a shot.  

The others will most likely be national credit tenants like Dollar stores and cell phone carriers.

Just make sure your insurance carrier can get it done right.In either case, you will need to have solid paperwork signed at closing to ensure you have the ability to cash an insurance check if you ever file a claim, namely a limited power-of-attorney from the borrower to your title-holding entity.

Just get their carrier (Sprint, ATT, T-Mobile, etc.) and you can email to their phone. 

That carrier, American Modern Home, may write in your state.
