Obviously you'll need to make sure you get a job/W2 income for at least 2 weeks to a month to get a loan to buy but luckily that's way easier than if you're having to work with 1099's starting out because most lenders require at least 2 years of tax returns at that point to get a loan.

Cold storage is one option but you can also look to use a hardware wallet such as the Ledger Nano S or X or even a trust service such as Gemini or Coinbase, which offer insurance on the funds held.

Even if your rate is in the 3's or 4's you can still get a rate in the 5's right now for a primary home and take out up to 85% LTV.

To clean a 2,500 sq. ft. house where I am located it's $195 for a good cleaner(s).
