Cashing out for house deposit…

I’ve held btc for a few years and my initial investment has grown to the point where its value is approaching something that I can use as a deposit for a house.

I live in a rental and have two young kids. Saving 80k is going to be near impossible with cost of living and income so firstly do people consider a house a fair asset to sell btc for?

Secondly it’s secured either a ledger and I was wondering the best was to off ramp it?

I was planning on using coinspot as I have been with thrm for a few years and liked how they worked.

Secondly I was going to do it in a number of transactions to reduce my risk of getting locked out due to some kyc reason (I’m fully kyc but you never know).

Lastly would people use the advanced coinspot trade service which I believe has lower fees?

Thanks

Edit I’m only looking to sell less than half a btc so is it even worth it given it’s not a massive amount? Just sell on the site as usual in 4 batches?
