MMR Development isn't a builder you hand plans to. We're your project lead from the lot you're considering through the day you hand over keys — at the table for market analysis, floor plan, design coordination, permits, utilities, and the build itself. Most builders start at the green tag. We start before you sign.
Most builders only know one side of real estate. Sebastian worked three before founding MMR. Each one adds an edge the next builder doesn’t have.
Five years as a plumber and crew owner. You learn what a real day’s work looks like, where the budget actually goes, and which subs cut corners the second the GC walks off site. Most builders never picked up a wrench. He used to run the crew.
Two years as a residential project manager at a real estate investment firm. Draw schedules, lender reporting, cost-to-complete, contingency burn. He stopped thinking like a tradesman and started thinking like the investor writing the checks.
Two years as an ICC-certified building inspector and plan examiner. Hundreds of projects a year. He learned exactly which framing details fail, which permits stall, and which electrical layouts trigger a re-walk — and now he builds with that knowledge in the room from day one.
Hand a builder plans and a permit and they'll build. Fine — until the lot turns out to have a setback issue, the floor plan doesn't pencil for the submarket, or CenterPoint takes 11 weeks for a service drop nobody scheduled. MMR is involved from the moment you own the lot, so those surprises get caught before they become draws.
Every MMR build runs the same seven stages. No moving targets, no mid-project surprises.
You've got a lot under contract — or you're thinking about one. Before you close, we walk it together. What builds clean here, what the submarket actually rents for, what configuration pencils. The conversation most investors don't have until it's too late.
Utilities located. Easements pulled. Soil report reviewed. CenterPoint queued. Skeletons get found before the design group spends a billable hour on plans.
With the site dialed in, we sit with the design group as plans are drawn — bringing the builder's eye and the inspector's eye to the page before anything goes to the city.
We're alongside the design group through plan submission, review, and city comments. One point of contact for you while the city does its job.
Budget, finish schedule, full timeline. The number you sign is the number you pay.
Weekly written updates with photos. Draws aligned to your lender's schedule. Real numbers — never “about 60% there.”
Final walk. Punch list closed. Certificate of Compliance delivered.
The core product. Side-by-side and stacked configurations purpose-built for two-unit cash flow.
Four doors on one foundation. Maximum unit count where zoning and lot dimensions allow.
Ground-up SFRs spec’d for tenant durability — not custom-home finishes you’ll never recoup.
Down-to-studs rehabs scoped for refinance appraisal. Every line item walks back to ARV.
5- to 12-unit ground-up and value-add. Built to commercial appraisal and lender standards.
Multi-lot BTR communities for portfolio buyers. One spec, one schedule, repeatable economics.
Sebastian's the guy you want on a project from day one — not just the build. He'll walk a lot with me before I close, talk through what makes sense for the area, sit with the design group, handle the city, and run the build itself. One point of contact from start to finish. Every duplex he's done for me has come in on schedule.
I underwrite my next deal already assuming Sebastian's timeline holds. After multiple duplexes with MMR, that's not optimism — it's a math input. Every other builder I've used, I had to bake 30 to 45 days of contingency into the pro forma. With Sebastian I don't.
My lender stopped flagging MMR draw packages within the first project. Weekly updates, real numbers, photos, and anything at risk on the schedule flagged before I have to ask. After two builders who ghosted me mid-build, this is what the bar should be.
A live look at what's on the boards right now — every stage of a build, running concurrently across the markets we serve.
Full project briefs and lender-ready draw schedules available on request.
Five jobs. One trajectory. Each stop closed a gap most builders never see.
It started underground. As a plumbing apprentice, the first lesson was that the things that fail a build are usually buried — bad slopes, sloppy stub-outs, drains roughed in the wrong spot. You learn that the cheap fix at framing is the expensive fix at finish.
As a licensed plumber and crew owner, the lesson became labor. You learn what a real day’s work looks like, what a fair bid looks like, and which subs cut corners the second the GC walks off the site.
As a residential project manager at a real estate investment firm, the lesson became money. Draw schedules, lender reporting, cost-to-complete, contingency burn. You stop thinking like a tradesman and start thinking like the investor writing the checks.
As a city building inspector, the lesson was the rulebook itself — code, intent, and which inspectors flag what. You see a hundred projects a month and start to recognize the patterns: which framing details get rejected, which electrical layouts trigger re-inspections, which permit applications stall and why.
By the time MMR Development was founded, all of it stacked. A builder who knows what’s buried, what a crew can really do in a week, what a lender needs in a draw package, and what the inspector is looking for before he opens the truck door.
That’s the edge. It’s not marketing language — it’s a résumé. Every stop on it removes a category of surprise from your build.
Sebastian founded MMR Development after a career that ran through every side of a build. Plumbing apprentice. Licensed plumber. Owner of his own plumbing company. Residential project manager at a real estate investment firm. And — most uniquely — a certified building inspector and plan examiner for a Houston-area jurisdiction.
That last seat is the one that changes everything. Inspecting hundreds of projects a year teaches you patterns no builder learns from the inside: which framing details get red-tagged, which permit applications stall, which electrical layouts trigger a re-walk. MMR builds with that knowledge in the room from day one.
