We finally got it rented! I got a call from a lady last Thursday who sounded a bit desperate - she just found out that morning that the lease on her current apartment was going to expire Monday and the apartment had been rented out to another tenant, so she had 5 days to find a new place and get moved in. So, she came and looked at the place that night, filled out the application and we signed the lease papers yesterday (Monday) and she got moved in last night.
We ended up doing it as a rent-to-own - she was able to afford the additional rent and she liked that some of her rent money would be credited toward a future down payment. (Incidentally, advertising it as "rent-to-own available" probably doubled the number of people that came to look at it. Good tip there, Lucas.) And we like that we're getting about 125% of the market rent.
The only thing left to do with it is to figure out the financing. We're still not sure which way we're going to go with that, but at least now we have some hard numbers that we can deal with. And having it rented is a huge load off our shoulders - looking at the financing options seems like a blessing now!
Thanks again to everyone for your help.
