AO Lot Development Takes 46 Acres on Highway 90 in Castroville

HWY 90 Castroville Partners Ltd deeded a 46.098-acre tract in Castroville to AO Lot Development LLC, according to a warranty deed with vendor’s lien recorded Oct. 8 with the Medina County Clerk.

For San Antonio-area builders and land brokers, the deed puts a 46-acre block on the Highway 90 corridor in the hands of a lot-development entity.

Why it matters

Castroville sits on Highway 90 about 25 miles west of downtown San Antonio, in Medina County. A lot-development buyer taking 46 acres there signals land being positioned for subdivision rather than a single building. The deed names no operating homebuilder or developer brand, so the end user of the lots is not yet on the public record. A vendor’s lien deed means the purchase was financed, with the lien securing the unpaid price until the loan is paid off.

The numbers

• 46.098 acres conveyed, per the deed’s legal description
• Instrument 2026010442, dated Sept. 10, 2026 and recorded Oct. 8, 2026
• Seller signed through MRR-GP LLC and MRR Services Company LLC, both listed as grantors
• No sale price: Texas deeds do not disclose one

What’s next

No plat, zoning case or permit tied to the tract has surfaced yet. The next verifiable step will be a Medina County plat filing or a City of Castroville agenda item naming a use for the site. A recorded release of the vendor’s lien would show the purchase financing has been paid off, and a later deed from AO Lot Development LLC to a homebuilder would show who is building there. We will track both filings in Medina County records. More: San Antonio →
