Seller preparation

What Porter and New Caney buyers will ask, and what to have ready

1. Creeks, floodplains and past storms

   Caney Creek and Peach Creek drain south through the area to the East Fork San Jacinto River and Lake Houston, and Porter MUD reports about 572 of its 3,966 acres in the 100-year floodplain of White Oak Creek and Bens Branch. Homes on Pecan Drive in New Caney took on 8 to 9 feet of water in Imelda (2019) after also flooding in Harvey (2017), per KHOU. Montgomery County has no countywide flood control district like Harris County's.

   • SJRA's Know Your Watershed viewer shows which watershed an address drains to.
   • Ask for the seller's disclosure, any elevation certificate and the flood insurance claims history.
   • Sign up for Flood Warning System gauge alerts after you move in.

   What buyers will do: Check the lot on the FEMA map and SJRA's viewer and get a flood insurance quote before the option period ends, even outside a mapped zone.

   What to have ready: Your seller’s disclosure flood answers, any elevation certificate, your flood insurance declarations page and records of any claim, repair or mitigation work.

2. County, school and the right water district

   Montgomery County's adopted rate was 0.3770 per $100 for 2025 and 0.3860 for 2026. New Caney ISD's 2025 rate was 1.2552 (the 2026 sheet lists 1.2393), and ESD 6 or ESD 7 adds 0.10 depending on location. Lone Star College (0.1058) and the hospital district (0.0458) are on the 2026 sheet. Most subdivisions then add a MUD, and homes inside Roman Forest add a city tax.

   • Texas school districts give a $140,000 homestead exemption; file Form 50-114 with the appraisal district.
   • A seller in a MUD must give you the district notice before you sign (Texas Water Code 49.452).
   • The seller's bill is not your bill: the value and exemptions change with the sale.

   What buyers will do: Look up the parcel's taxing units with the appraisal district and price the bill with the exact MUD before you make an offer.

   What to have ready: Your latest tax statement with its list of taxing units and your exemptions. Buyers know their own bill will be figured on their own value and exemptions, so a clear breakdown helps.

3. Unincorporated county rules

   Outside Roman Forest there is no city government, so roads, permits and floodplain rules come from Montgomery County. Since Oct. 1, 2025 the county requires a permit for any development on a property unless an exemption is clearly listed. Rural tracts without district sewer rely on on-site septic systems, which TCEQ regulates through local authorized agents.

   • Permit and floodplain questions go to the county's permit and floodplain offices, not County Engineering.
   • On acreage, ask for the septic permit and maintenance records.

   What buyers will do: Confirm whether the property is in a city, a MUD and an HOA, and ask the seller for permits and septic records before you close.

   What to have ready: The recorded deed restrictions for your section and the permits or approvals for past additions, pools, fences and remodels.

Insurance and disclosures: buyers will price homeowners and flood insurance before they commit. Have your current declarations pages, any elevation certificate and any flood-claim history ready; Texas sellers also answer flooding questions on the seller’s disclosure notice (Texas Property Code §5.008).
