Unincorporated Areas / Well Water Systems

[Bradley Calvin]

In looking for a property to fix and flip, I came across a property in an unincorporated area in a desirable town. The house has a private well water system. Based on the comps in the area, it's not a good deal, but it made me wonder if other rehabbers consider private well water systems a red flag to stay away from, or just something to account for in the analysis (longer TOM on the sale side maybe?). Would you stay away from unincorporated areas in general, or is this a non-factor?

Any shared experiences would be much appreciated!
