A better approach would be to borrow against your BTC and never sell. Avg. yearly returns sit at 55% and are projected to drop over time but remain at around 30% for the next 30yrs. Interest on borrowing against your BTC is about 12% p.a. and will go down over time as adoption increases.
Discussion
I've analyzed combining real estate with Bitcoin and do believe BTC can enhance real estate, but I think this comparison is focused on the appreciation and not the cash flow analysis.
2 additional models are being adopted by landlords:
1. Monthly cash flows from rent payments are being pushed into BTC.
2. Real Estate is being used as collateral to buy more BTC.
In both scenarios, BTC appreciation will push the business case even higher and depending on the amount being dollar cost averaged into BTC, the returns from BTC will eventually surpass the rental income.
We are looking at distributing dividends on Lightning. There is so much Bitcoin can do for real estate.
