I’m not finding that Banks are ready to facilitate these, and even though education is happening, it will be a while before they have structured products throughout the market. So that solves the custody problem. Fully self custodied cold storage bitcoin. Your keys, your coins. You are just putting that bitcoin on the books alongside your holding of the property to do the cost and performance model calculations in tandem. Battery Finance showed up on Squawk Box having done this for an apartment complex, but they are the only ones I know of that are a financial institution doing a mortgage and holding bitcoin both. They wanted to hold the bitcoin for five years, even in case of an early loan payoff. Not sure why, unless they are re-hypothecating. That would be a no-no for me. The only other option I can see would be to incentivize a longer active loan period even if bitcoin spiked and facilitated an early payoff two years into the loan. This would mean that if you borrowed 60% of the property value in a mix of cash and bitcoin, then the bitcoin tripled in value allowing you to pay off the loan after one year, they would still get five years on the loan because your bitcoin is locked up with them for five years. I’m guessing on their inner workings, of course. I don’t know why else they would put a five-year required term on the bitcoin hold. The models I run are on houses where you may have 40-60% equity, and could borrow 10-25% equity for a smash bitcoin buy. This force is a low time preference because you’re looking at a 10 to 20 year old on that bitcoin. You’re gradually paying it down at a 5 to 8% annual interest rate. Or if it’s a rental property you calculate this so that the rents buy your bitcoin. There are more moving parts to this, but this is the gist.
