Question about Days on Market -How important is it?

[Arthur Fuller II]

when running comps on areas where I see homes I'm interesting in flipping I notice that in the past 3 or 6 months there might be good activity (several sales) but the mix of DOM is very wide.. there might be 3 homes that sold in under 45 days and then 4-5 that too over 180 days to sell. The remodels don't look vastly different. Is this just a case of by vs good marketing by the people/agents selling those rehabs?
