If I read your original post correctly, here's what you have:

1. 800+K of mortgage debt (when TOP)
2. Expense of 1.7K a month on rent (now)
3. 156K invested in trust fund (now)

First, I would say that your mortgage debt is too high unless you are a high income earner or you will pay down even more before TOP. What's your debt to household income ratio?

Second, putting so much money in trust fund is, IMHO, not wise. You are giving your money to fund managers to play with, with no accountability or responsibility. Basically you have absolute no control over your money after you sign on the doted line.
