Montgomery County property values have risen 12.5 percent on average since last year, and The Woodlands Township, Shenandoah and the Rayford Road corridor have all seen an overall market value increase, according to Montgomery Central Appraisal District data.

By and large, the market value of residential properties in Montgomery County, including new construction and development, increased by 11.2 percent on average.

“We mailed out approximately 180,000 notices of appraised value this year,” MCAD Chief Appraiser Mark Castleschouldt said. “That covers residential properties, commercial and business personal properties.”

The MCAD office has already started seeing property owners who wish to protest the increase because it causes their property value to rise. To file a protest, property owners must present the Appraisal Review Board with a written protest letter with a U.S. Postal Service cancelation stamp with a time and date no later than midnight of the protest deadline. This can be delivered in person or via mail. Property owners in Montgomery County have until Tuesday, May 31, to protest their appraisal.

Overall, the township’s market value increased 5.9 percent; Shenandoah’s market value increased 12.5 percent; and the Rayford Road corridor experienced a market value increase of 12.9 percent. This includes all pre-existing properties, new construction and development, and commercial, residential and business personal property.

“Most residential markets went up,” MCAD Deputy Chief Appraiser Tony Belinoski said. “The commercial market [increased] not as much as we’ve seen in the past. I think a lot of that is due to The Woodlands area starting to peak out on their building area.”
