Mariah Bay
An established, rolling-hills Heath neighborhood on the Lake Ray Hubbard side of town
Mariah Bay is a smaller, established Heath neighborhood on the southern, Lake Ray Hubbard side of town, with roughly 83 lots. Most of its homes were built from the mid-1980s through the 1990s, and many now sit on generous lots with mature trees and landscaping that give the streets privacy and shade. It trades the resort amenities of Heath’s newer master-planned communities for lower entry pricing, larger established lots, and a quiet, settled character - while keeping the same Rockwall ISD schools and the town’s lakeside setting a short drive away.

Check these before you offer
The trade-offs a listing will not mention. None of these are reasons not to buy here; they are the things worth pricing in.
- It is near Lake Ray Hubbard rather than on it. Buyers who want true waterfront with a dock and sea wall should be looking elsewhere in Heath.
- The homes date from the mid-1980s through the 1990s, so roofs, HVAC and original finishes are broadly at or past their replacement point.
- The association is voluntary with modest dues, which means little in the way of common-area upkeep or architectural control.
- At roughly 83 lots this is a small subdivision. Inventory is limited, turnover is slow, and true comparables are few.
- Rockwall ISD zones by area rather than by Heath's town limits, so a Heath address does not fix the elementary campus.
- No passenger rail, and roughly 30 minutes to downtown Dallas via I-30.
