Mooney M20K 231 financing FAQs
How much does a Mooney M20K 231 cost?
Typical asking prices for a Mooney M20K 231 run from about $65,000 for older or higher-time examples to $140,000 for late, low-time ones, with most trading near $95,000. Engine time, avionics, damage history and paint/interior drive the spread — confirm with a Vref or Aircraft Bluebook valuation and a pre-buy inspection.
What is the monthly payment on a Mooney M20K 231?
At a $95,000 purchase price with 15% down ($14,250), a $80,750 loan over 20 years is about $663 per month at 7.75% APR, or roughly $626–$779 across the 6.99%–9.99% range lenders published as of September 2026. Principal and interest only.
How much down payment do I need for a Mooney M20K 231?
Plan on at least 15% down for a single-engine aircraft built after 1960. Twenty-year terms are generally available on loans of $75,000 or more.
What does a Mooney M20K 231 cost to fly per hour in fuel?
At about 13 gallons per hour and the September 2026 national average of $7.24 per gallon for 100LL, fuel alone is roughly $94 per hour, or about $0.49 per nautical mile at a 191-knot cruise. Add reserves, insurance, storage and the annual for the full picture.
Can I finance an older Mooney M20K 231?
Usually, yes. Lenders finance piston singles without a fixed age limit, though pre-1960 aircraft may need a larger down payment and shorter term, and airframes over 10,000 hours are often excluded. Complete logbooks, AD compliance and a clean pre-buy matter more than the year on an older M20K 231.
