Just know the risks of it. We are still in a bear market so expect the unexpected. Always expect that there is a chance that Bitcoin might go down even lower from its current price. Some are saying that what happened in 2022 will continue in 2023. Take note as well that this will take time for you to take profit and there is a chance that what you're thinking might not happen as well. A risky move but the rewards are high when the bull run comes. You got a second home so I guess it will not hurt you that much if you will sell your first house as long as you're comfortable with your 2nd home and it got it all that will help you to live.
Can't guarantee when investing in Bitcoin always profitable and price increase up years by years, we can track with this year Bitcoin price drop drastically after in 2021 ever reached and make all time high price until above $60,000. Seems OP need think clearly about risk waiting for when selling his second house and used it to invest with Bitcoin, not always earn profitable although many promising people said excited when investing in Bitcoin, moment Bitcoin drop drastically until $17,000 from highest price on $60,000 become experienced for OP if serious want to sell house for Bitcoin.
