#617: How to Avoid the GC Mistake That Turned a $1.2M Bid Into a $2M Build

Three years into a Denver luxury redevelopment, Paul DeSalvo knows what real estate development mistakes actually cost. Paul, a Denver real estate investor and broker, is back to walk through every one of them. In this episode, Paul returns to update host Chris Lopez on a sweeping redevelopment in Berkeley, Denver — a 1902 Victorian transformed into a 5,500 sq ft, 6 bed/6 bath luxury home with an 850 sq ft ADU and 3-car garage. He shares what went well, what hit hard, and what every investor should know before breaking ground on a project like this. The budget surprises alone tell the story. A foundation that needed a full rebuild added $75,000 to the project. An asbestos mass spill ran $30,000. Denver’s Affordable Housing fee — charged on any addition over 400 sq ft — came in at $25,000, a cost neither Paul nor his GC had flagged. A new water line tap added another $12,000. Combined with items left off the original budget entirely and inflation across lumber, drywall, and appliances, the project pushed well past the original estimate. The contractor selection story is the most instructive of all the real estate development mistakes covered in this episode. Paul and Val interviewed five or six GCs. Most bids came back between $1.8M and $2.1M. One came back at $1.2M. They went with the low bid. That contractor’s experience turned out to be primarily remodels and pop-tops — not ground-up luxury construction. By the time the project wrapped, costs had converged right where the other bids landed. Paul walks through exactly what he would look for differently and why verifying the type of experience matters as much as verifying the experience itself. In this Episode: Why the lowest GC bid on a luxury build is often the most expensive choice How to verify contractor experience by project type, not just project count The Denver Affordable Housing fee and how it catches smaller developers off guard What scope creep actually looks like on a high-end redevelopment and how to manage it Why architect and builder coordination failures cost more than either party’s mistakes alone What has gone well on the project and what Paul is genuinely proud of Paul’s honest take on whether he’d take on a project like this again If you are planning a luxury build or any ground-up construction project in Denver, this episode is a practical field guide from someone who has lived every one of these real estate development mistakes and made it to the other side.
