Custom home building is terrifying. One wrong number on a bid, one missed detail in a contract, one bad builder match, and you're $200k underwater on the biggest purchase of your life. We end that risk. You get the same 60-page, builder-grade spec sheet a $5M client signs and a vetted local builder who actually returns your calls. Upgrade to Concierge and we personally quarterback the whole build, including a written plan to carry rent and a construction loan. Flat fee. No kickbacks. No guessing.

"Finally, someone speaks our language."
The risk nobody warns you about
A single missed allowance, a vague scope line, an undersized HVAC spec, and your $850k build quietly becomes $1.1M. Most first-time buyers never see it coming until the change orders start landing.
Great regional builders are booked 18 months out. They will not waste an afternoon educating someone without a real spec. Show up empty-handed and you get the builder nobody else wanted.
No banker, no realtor, no builder will sit down and map this out for you. So you wait. Another year of rent. Another year of rising costs. Another year of the home not getting built.
This is the largest check you will ever write. There is no undo button on a foundation pour, a framing mistake, or a builder who disappears mid-project. The cost of getting it wrong is generational.
What you get
The exact document a $5M+ custom home buyer signs, calibrated to your budget, lot, and climate. Every product, brand, gauge, and R-value spelled out so a builder cannot hide cost in vague allowances. You stop guessing. They stop padding. Bids become apples-to-apples for the first time in your life.

Real homeowners

"We thought we'd be renting until we were 40. BuildProof gave us a spec sheet, three builder intros, and a plan that actually works on our income. We're breaking ground in May."
Maya & Jordan
Portsmouth, NH, first-time builders, age 29 & 31
"I'd been ghosted by six builders before I found these guys. Walked into the next meeting with a 60-page spec and the builder said 'this is the most prepared client I've had this year.'"

"The finance plan alone was worth the fee. They mapped out exactly how we'd carry rent and a construction loan for nine months. No bank had ever shown us this."
