Homes that resell within 90 days are fix & flips. Yes, they sell for a higher price, but there is also more investment put into them than just the purchase price.
I guess it would depend if the first sale was brokered by a private individual or by a real estate agent. One would tend to think that most agents would price a home close to market (since they have more information of market pricing than the average person) and prices closer to market would be hard to flip for a large spread in a short period of time.
How do you know it _wasn't_? We basically have a _whole bunch_ of possible hypotheses here that the data/analysis here does not allow us to distinguish.
That seems like an unwarranted assumption. How do you know any fixing was involved?
