Rehab tool accuracy question

[Luke Stewart]

Hey, I am in the process of buying a true duplex house hack and I was curious if anyone finds the Bigger Pockets Rehab Estimator tool to be accurate. The property has a small kitchen 212 sqft, I want to redo the tile floor, and new cabinets, counters, sink, and appliances. I would estimate 3 top cabinets, 4 lower cabinets, and at most 25 sqft of countertops (quartz would be the first choice), and a new fridge, dishwasher, and oven/microwave. The estimator is giving me a $63k rehab for the kitchen. This seems insane to me as when I do product lists from home depot or lowes I can barely get over 10k for the total cost of supplies. Even if I go expensive and spend 15k on supplies have a hard time seeing there being almost 50k in labor. Just curious about other's experiences with the rehab calculator.
