For investors- how important a good school district?

[Maayan Cohen]

How important it is in the screening process for buyers investors,  to look for investment properties that are located ONLY in a good  school district areas really? 
especially when you see lots of properties in the neighbourhood that were leased relatively quickly ( in 2-30 days) - numbers are working to the investors ! 
Also Townhomes in this community sell quickly and over asking price ! 
what are your thoughts on that? Working with first time investors !
