@Matt R. it's definitely a solid investment but only if you understand it's value and potential (the same as picking a stock to invest in). btc has made life easier for many people across the world (think cross-border remittances), but I can understand why some folks avoid like the plague.
I would accept btc but there's things I'd consider. Let's say I normally charge $2k usd for rent, how much would I charge in btc? Personally, I'd want to charge enough to make $2k usd after conversion and taxes, plus have enough btc leftover to hold as an investment. It'd be hard for me to justify collecting rent in btc without converting some to cash and holding some as an investment.
In the future, I think blockchain helps with easier transfer/distribution of equity for real property (see Fortem), title/escrow/closing (see Qualia), and others. Imagine how much easier it'd be to access public record to find info about a property if it was on a blockchain. Wholesalers should probably be blockchain activists.
