Harlingen build questions.
How much does it cost to build a custom home in Harlingen?
It depends on plan, lot, and finish tier. Our prices begin at $110 per square foot, and every project is different. The RGV Custom Home Planning Guide covers what moves that number.
How long does it take to build a home in Harlingen?
From contract to keys, a typical Sisu custom home in Harlingen takes 6 to 10 months, depending on the size of the home. Weather rarely slips the schedule by more than a week. The biggest variable is allowance items like cabinets and tile, where lead times can stretch.
Can you build on a lot I already own in Harlingen?
Yes. Bring us the survey and the soils report (if you have one) and we’ll price the build on your specific lot.
Do you build commercial in Harlingen?
Yes. Sisu is a Texas General Contractor and we take on commercial projects in Harlingen on a case by case basis. See our commercial page.
What’s the difference between Sisu and a production builder?
Production builders work from a fixed plan library and a fixed finish menu, in a fixed subdivision. Sisu builds custom: your plan, your lot, your finishes. The trade off is timeline and decision count. The benefit is a home built specifically for you, by the person who quoted it.
