What buyers should know
Flood insurance is a real cost here, not an afterthought. Check the FEMA flood map for the specific parcel — the San Marcos River, Blanco River, and Purgatory Creek all have flood histories, and the 2015 Memorial Day event exceeded what FEMA maps predicted.
Know which side of the Balcones Escarpment your home sits on. West-side limestone lots behave differently from east-side clay lots; expansive clay is the main culprit behind foundation movement in the I-35 corridor and eastern neighborhoods, so a thorough pre-purchase foundation inspection is worth the cost.
San Marcos has seen some of the steepest appraisal increases in Texas due to rapid growth between Austin and San Antonio. Factor in potential year-over-year tax increases when budgeting, and check if the property carries a homestead exemption that will limit the increase after your first year.
