If you can make dollars you will want to purchase in those dollars.

If you have Bitcoin and you can not earn dollars buying a house might be a good decision if your Bitcoin can cover the expenses and taxes of a home over your lifetime. If you can not do this then buying a house doesn't make sense because in the future your Bitcoin will buy 30 houses.

The Dollar is decreasing with money printing, non-actional reserve and debt to dollar creation.

Bitcoin is a way to take a tiny bit of FIAT and build generational wealth. Another principal in buying something with Bitcoin is using sats.

Sats are cheap now so you are just moving around tiny bits for things you like at your value for value price. As a vague for value receiver you save the majority and you send small amounts to your favorite value for value.

If you do make a big purchase like a house make a very low Bitcoin offer based on what that Bitcoin will be worth in the future.

"I'll pay 50,000,000 sats for this house as it will buy 30 of these in the future."

There are people who will offer a bag of cash for your home now. Totally undervalued but the owner gets cash that is a bearer instrument.

If you understand humans then that is the key to understanding Bitcoin and Fiat currency or any type of negotiation.
