Hi Tynan,
Interesting post/ thoughts.
I’ve done something similar where we bought a parcel of land and leveraged $ from the brokerage account (Wealthfront). I am also using BlockFi which pays 8.6% interest on GUSD.

Wealthfront charges 3.7% on margin loans, which is higher than the 1.6% you mentioned in your post. Do you know if I can transfer my margin loan?
