Creating a Bitcoin Reserve from rental property

Let's say that you own some rental property that you are able to keep 100% of the rental income in a HYSA and make the payments for mortgage, insurance, and taxes without touching that rental income. I want to start taking that income and build a bitcoin reserve with.

One of the problems I run into is when I need liquidity for repairs or large expenses, that is the time I use that money sitting in the HYSA. However, I don't need 100% of that sitting in the HYSA.

Doing the math it seems that exchanging every months income directly into bitcoin and holding it would be the better option, but having to pay taxes and fees for getting liquidity for expenses would not be ideal.

So I'm thinking that exchanging a large portion of the current balance into bitcoin, like 60-75%, into bitcoin now. And then 50% of future payments into bitcoin and the other 50% to sit in the HYSA. Maybe scaling this up with more into bitcoin as the liquidity equals a comfortable amount.

Has anyone done something similar? If so, what have you found to work best for ultimately stacking as many sats as possible but having liquidity to handle emergencies or unexpected large expenses?
