The builder went in-house at month nine. That cost me $141k.
Construction is what I know, so when I got my broker license the plan was obvious to me. A brokerage specializing in new construction resale and inventory listings, staffed by agents who can read a spec sheet and talk to a superintendent without embarrassing themselves.
I had a handshake relationship with a regional builder doing about 140 homes a year across four communities. Not a contract. A relationship, built over eleven years of me being on their sites in a different capacity. They were listing spec inventory with two different agents and complained about both.
I signed a 36-month lease at $3,100 a month for a small office near their newest community. Hired three agents and put them on draws of $4,000 a month against future commissions for six months, because none of them had the reserves to wait out a new construction pipeline. That's $72k committed on day one. Plus buildout, signage, and a coordinator part time at $2,100 a month.
Month nine the builder announced an in-house sales arm. Two of my three agents were recruited into it directly. The draws were technically recoverable and I recovered about $9k of $72k, because you can't collect from people with no production.
Wound down at month 11. Lease buyout $18,600, unrecovered draws $63k, everything else about $59k. Roughly $141k of my own money.
What I'd do differently: no single source of inventory above maybe 30% of projected revenue, and a written listing arrangement before a lease. I'd also do draws as a loan with a note rather than a recoverable advance in an IC agreement, if my state allows it, which is a question for an employment attorney and not for me.
