Million Dollar Mistakes™
Seven mistakes that cost the most
One card each. What the mistake is, why it happens, what it looks like early, and what to ask next. Nothing to buy — just the next decision, made with confidence.
01Choosing a builder by the model home
The model is a showroom. Your house is built from the base spec.
Cost if ignored · $15k–$60k in upgrades you assumed were included
02Signing without your own inspection rights
If the contract does not allow your inspector, the answer later is no.
Cost if ignored · $5k–$40k in defects found after closing
03Spending the option budget on finishes first
Finishes can be replaced later. The envelope cannot.
Cost if ignored · $1,200–$2,400 a year in comfort and utility cost
04Skipping the pre-drywall walkthrough
It is the last day you can see how your house was actually built.
Cost if ignored · $3k–$25k in hidden defects
05Letting the HVAC be sized by rule of thumb
Bigger equipment is not better comfort — it is short cycles and sticky air.
Cost if ignored · $600–$1,500 a year, plus early equipment wear
06Accepting verbal promises at the walkthrough
If it is not written, photographed, and dated, it is a hope.
Cost if ignored · $1k–$10k in repairs you end up paying for
07Missing the 11-month warranty window
Your broadest coverage quietly expires around month twelve.
Cost if ignored · $2k–$20k in repairs that were covered a month earlier
