Then my passive income would solely come from stock investment.2.

Even if you own a property in TX, you are conducting business in CA because you live here, collect the income here, etc.

I wonder would the rental income cover the monthly interest payments on the crypto loan?

@Charles Perkins is absolutely correct about "collecting all receipts, properly tracking all income and expenses and your basis for all assets properly documented and recorded."

As for financing, make sure to explore options for using rental income to qualify, and be prepared for a 20% down payment.

Most lenders require a leased property to qualify for a cash-out refinance, especially with a DSCR loan, which is based on rental income.

My wife and I are eager to build multiple streams of income, and we believe real estate investing, particularly in multi-family homes, is a great way to achieve that goal.

@Kaleb JohnsonRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Checking: collect all income here, then use it to pay bills.

You do have to keep an eye on your write offs to ensure you are showing a good NOI and not using too many write offs to show enough income to use for bank/lender underwriting on a mortgage/loan.
