After getting approved to remove PMI that was paid upfront two years ago, what percentage would I get back?

Generally, nothing comes back. Most upfront mortgage insurance is non-refundable once paid. The details depend on which kind of coverage you had: - Single-premium or upfront PMI (conventional): can be structured as refundable or non-refundable. Refundable versions cost more upfront to buy, which is why most files skip them and most people have never heard of them. If yours was refundable, the amount steps down over time, so two years in you'd typically get back less than you would have in year one. - FHA upfront MIP: generally non-refundable, with one exception: refinancing into another FHA loan within 3 years, where a declining refund schedule applies. Simply cancelling coverage doesn't trigger it. - Monthly PMI and monthly MIP: not refundable. The way to know for certain is to check your original loan documents from closing, or call the servicer or mortgage insurance provider and ask whether your policy is refundable and, if so, what the current refund schedule shows. Don't count on money coming back, but the call is quick and worth making before you assume one way or the other. If the documents don't spell it out clearly, the insurer or servicer can tell you which type you have.
