We recently moved into a house built in 1980 but was renovated by an investment company. They did a beautiful job and everything passed inspection but we have lived here a month now and I have noticed some red flags. The counters in the kitchen are not the same height on either side of the stove. The floors have disconnected from the wall and I recaulked but it disconnected again. I believe there used to be a wall where they separate and they removed it in the renovation. They put new door frames and doors everywhere but the upstairs doors stick. Should I be concerned or am I just being paranoid?
