Kinda in the same boat. Actually considering an addition and a pool with a heloc. Bought last summer but thankfully still have some equity. My thought is I wont sell any btc to improve house so it is either use my cash or someone else’s. If I use someone else’s cash mine can be invested in btc and I can chip away at the extra note with bonuses and commission checks. This would allow me to keep stacking btc and even when I gets checks in I will still use a portion to buy btc. I dunno I get the feeling my friends and family think I am crazy😂🤷‍♂️
