Quote from @Cristen Marcotte: Has anyone worked with this broker/lender?

Solid broker, I know Dan personally.

There are a ton of qualified broker and lenders out there that can offer this product but be sure to receive the proper education when iyb comes to structuring the deal correctly.

I've contacted 8 insurance companies/brokers and no one offers policies (issue being the subleasing).

I look for a highly recommended mortgage broker and see what interest rates and mortgage products they have.  

Find an Insurance Broker that can shop the market.

The vast majority of "regular" or traditional (Conv/Govt) mortgages are originated by specialty lenders and brokers and are sold in the secondary market to provide yield on bank balance sheets (think Chase or BoA) or to be securitized into MBS.

If you're interested in an insurance broker that can help you with that, msg me and I will provide a local name of someone that can walk you through some options. 

Running through some dry scenarios with brokers and lenders would be a good way to get your feet wet.

robert  not sure about you but I find it pretty difficult to sell one off new builds without the help of a RE Broker which is what RTR is in those situations..
