Before you move here
The Good, The Bad & The Reality.
Want a custom home on a big wooded lot, behind a gate, on a quiet Lake Conroe inlet? Grand Harbor has that. But the association does not post its dues, there is no golf or grocery inside, and a waterfront lot comes with SJRA dock and septic homework.
The Good
- Larger lotsHAR's 2025 facts put the median lot at 26,572 square feet, compared with 7,688 in Walden next door.13
- Gated on a Lake Conroe inletCommunity Impact described a gated neighborhood on a Lake Conroe inlet with houses on the waterfront, near the Walden Yacht Club.4
- Boat launch and a 10 acre parkThe same profile listed a boat launch, a 10 acre inland park, jogging trails and volleyball and tennis courts.4
- Newer custom homesHAR's median year built is 2007 and the median home is 3,532 square feet, and Community Impact listed various custom builders.14
- No MUD on HAR's tax tableHAR's tax table for Grand Harbor lists Montgomery County, the hospital district, Montgomery ISD and ESD 2, with no utility district.1
The Bad
- Dues are not postedWe found no association website with the dues, so the resale certificate is where you see the assessment and any transfer fee.4
- A higher price pointHAR's 2025 median market value is $778,871, with a range of $536,000 to $1.21 million.1
- Docks and bulkheads need SJRA paperworkPrivate docks need an SJRA license with an annual fee, bulkheads need their own permit, and SJRA does not promise any lake level.1314
- Septic rules near the shoreSJRA permits septic systems within 2,075 feet of Lake Conroe, so ask how the home handles sewer and check SJRA's OSSF Data Viewer.15
- Golf and groceries mean a driveThere is no course inside; the nearest are the private Walden club and the Margaritaville resort course, and the closest confirmed groceries are on SH 105 in Montgomery.56
The Reality
- Michael’s bottom lineGrand Harbor is for a buyer who wants room, a custom house and the lake without a golf club in the package. Because the association does not post its dues, I would get the resale certificate early, confirm the tax units and the sewer setup, and on the water ask for the SJRA dock license and bulkhead permit before anything else.

Michael’s Take · broker opinion, based on the sourced facts above
My take: Grand Harbor is for a buyer who wants room, a custom house and the lake without a golf club in the package.

- 2A higher price point
HAR's 2025 median market value is $778,871, with a range of $536,000 to $1.21 million.
- 3Docks and bulkheads need SJRA paperwork
Private docks need an SJRA license with an annual fee, bulkheads need their own permit, and SJRA does not promise any lake level.
SJRA: Licensing my residential structure SJRA: Permitting my bulkhead
- 4Septic rules near the shore
SJRA permits septic systems within 2,075 feet of Lake Conroe, so ask how the home handles sewer and check SJRA's OSSF Data Viewer.
- 5Golf and groceries mean a drive
There is no course inside; the nearest are the private Walden club and the Margaritaville resort course, and the closest confirmed groceries are on SH 105 in Montgomery.

Michael’s Take Broker opinion, based on the sourced facts above
My take: Grand Harbor is for a buyer who wants room, a custom house and the lake without a golf club in the package. Because the association does not post its dues, I would get the resale certificate early, confirm the tax units and the sewer setup, and on the water ask for the SJRA dock license and bulkhead permit before anything else.
