It's unlikely that the rental returns would catch up to the initial capex required to acquire the house. Plus on top of that you have opex (maintenance/insurance/taxes/debt servicing) as well as the counterparty risk of shitty tenants, risk of loss of the asset (fire, earthquake) and seizure risk (eminent domain, failure to pay property tax etc.). Then, god forbid, should you ever want to unlock your equity, you have to sell the *whole* house. Bitcoin destroys property as an investment class across all metrics (other than, possibly, volatility), which is why, long-term, it will drive property prices down to their utility value.
