$13 HOA fee?? make it make sense

House hunting and seeing homes with $13 monthly HOA fees has me completely baffled. What could this possibly cover?? One light bulb change per year? Half a shrub trimmed? Most HOAs I see are $150+ with actual amenities. Is this a trick before they quadruple it later? So confused right now! 🏠😵 #firsttimehomebuyer #realestate #HOA
