et cetera,
If you are still tuning into this thread, and I do know you're investigating other options based upon other threads, but, I did have one other thought.
With the income you said you are making, I'm assuming you should have some sizable amount in savings. I know you said you had a lot of "charity contributions", but I'm assuming you're taking care of your own financial needs as well and setting aside a comfortable portion.
So, if that's the case, have you considered getting a secured personal loan on say $20,000 worth of savings? My wife's niece needed a personal loan several years ago to help pay some legal fees as a result of her divorce. The loan rates were unbelievably high for a personal loan. I contacted my credit union, and we ended up transferring $10k to an account, and she borrowed against that for about 3% interest.
Just wondering if that would be an option for you to consider? Obviously, you need to have some money available that you don't need access to. But as you pay off the loan, you have access to the principal that you've paid off.
Good Luck,
