It's a new month so I'll need to post an update here, as things have changed and new terms haven't been established in this thread.
I have received a partial repayment at the beginning of last month of 0.22004658 BTC. That leaves the remaining principle at 0.22995342 BTC. When the principle was .45 BTC, the interest on this loan was .015 BTC a month - 3.33%. For September, October, and the months going forward, I will simply round the monthly interest down to 3%. Currently, that is 0.00689860 BTC. You only need to pay interest on the principle, so any other partial repayments will further reduce this amount.
Collateral coverage is great, and as long as it remains that way, this loan can be kept open indefinitely.
I trust that these are agreeable terms. As they are better than the previous months', I hope they are well received and we can simply continue on with them being outlined here.
Cheers,
Hatcher
