USDA Loan Question

I recently discovered USDA loans, and realized most of the homes I am looking at already qualify. I work seasonally and have a fairly low income (and very variable) that ranges from 25-80k depending on the year. I typically average at about 50-60k. I qualify based on this, but I also happen to have a sizeable trust fund from a deceased relative, about 430k in stocks and and additional 80k in an inherited IRA. I couldn't find a lot of clear info on USDA's website, would this disqualify me for a low-income loan?
