My husband and I have been looking at building a tiny house (
http://www.tumbleweedhouses.com/) for many years. There's lots of folks that have blogged about building there own. One young couple borrowed money from lendingclub to do it. They posted about their loan progress funding progress on their blog. They didn't qualify for a construction loan because it wasn't on a fixed foundation, and they couldn't qualify for an RV loan because it wasn't built yet, so this was their option for funding.
That was back in '08 (I think). I would futz around online reading about different strategies from different blogs for a long time. I invested ~100$ in Jan of 2010. I was really careful, and selected some G grade notes. There was a default, and lots and lots of late payments, but my ROI stayed above 11% even with the minimal diversification I had. I got more confident and continued to research.
I did a bunch of contracting work last year so I had a bit of cash that I could invest in an IRA for 2012/2011 at LC and not get charged the fees. I started by mirroring the investments that Ken was making public on his forum at lendstats. I had a bit of a crisis of faith when the site went down this year, I found some old post that gave me the rough filtering strategy that I later refined into my own filters. I transferred my filters to Excel so now I can download the browse notes file from LC and do my own filtering. I owe a lot to Ken for getting me started on the right filtering path (at least one that works for me).
I'd like to eventually run my own statistical analysis in Excel, and automate more of how I select notes, but I'm seeing good returns (so far) and I'm not quite ready to unbury my stats book yet.
