It's interesting that this thread came so close to predicting the future! Now 7 years later, and payments for long term rentals throughout the US are soon going to be paid in BERRY, the token released over the last few months by Rentberry.com.
In 2011 the idea of there being 1400 altcoins would have been hard to imagine let alone, another cryptocurrency other than BTC being the future medium for payment between Landlords and tenant, but now the Rentberry project have incorporated blockchain tech into their web platform and are close to finishing the development of their app - which will connect property owners and renters globally.
Currently their platform has thousands upon thousands of listed properties in the US, and expansion to other countries around the world will be commencing later in 2018.
Landlords are already able to make payments for e-signing contracts with tenants and listing multiple properties in BERRY, and soon tenants will also be able to pay for their rent using the token as well. Also built into the core of the Rentberry model, is the ability for token holders to earn roughly 7% interest in passive income from lending renters BERRY tokens to crowdfund their security deposits.
Unlike projects such as Bee, Rentberry aren't taking on big players like AirBNB head on - their target market is the long-term (think furniture-less) rental market.. a space which as of now hasn't been seriously considered by blockchain enterprises.
