I have an urgent request send to your e-mail that I hope you can look at ASAP. It's of such importance that I will pay you extra, just to read it immediately, and hopefully take care of the matter swiftly. See e-mail for the personal details.

Thanks.

The thing is, that I only need to lend the BTC for 16 months and return with fixed percentages. 

Thanks for the feedback. Andy yes, it would make sense to have a Norwegian lender in this case.

Believe me, I've tried getting a loan through the bank, but due to my income situation they have rejected it.

I am fully aware of that. It's a little more complicated proposal I have in mind, and it needs to be discussed properly first. I will address the proposal directly only.

I want to borrow up to 500 BTC, putting my real estate as security for it. To have full security for the loan it needs to be filed in the national asset registry in Norway.I want to use a smart contract platform for the execution, but I am unsure on how to register the claim in the national registry.

I don't see why a loan in cryptocurrency should be any different then fiat if we provide loan documents.  Maybe it's not a problem at all?

The terms I offer is VERY GOOD. By request we can discuss it by phone, Skype or e-mail. 

As far as I know this has not been done yet, but circumstances has led me to it by necessity.

I want to use a Smart Contract platform to execute the transaction, but I am unsure how it will be registered in the public database of the Government in this regard. Anyone?

By request we can discuss the matter on Skype or e-mail.
