So this happened last night:
1) I have a new tenant for the vacant unit in my duplex. He's a friend and colleague of the upstairs tenant, who is a friend of mine, so that's awesome.
2) Another friend with the right sort of ethical stance (neighborhood-oriented, rather than profit-driven) is interested in buying the duplex!
3) *Another* friend expressed interest in buying my house.
If all this gels, I will be able to complete my move to Texas within weeks!
