I live in one of the more rapidly growing American metros, in what I would consider a construction boom. I'm not sure what you're characterizing as a startup, but if you simply mean a new business without a lot of history attempting to enter the market and compete, as far as I can tell, there are a lot of these. My own home was built by a small builder, single-owner, who had been in business less than a decade. Three separate adjacent lots were purchased and at least started to be developed by first-time homebuilders. In two cases, they failed and sold the project before even completing it, but someone out there was at least trying to be a homebuilding startup. You may be thinking of new businesses attempting to grow fast and capture market share using equity investors to subsidize low initial prices charged to consumers. I'm not sure that makes sense as a business model in the residential construction sector. Your revenue just comes from selling houses. Pricing is a fairly strict matter of supply and demand you have little to no control over. There is no alternative revenue model. People buy the house and tend to stay there a while. They're not going to buy a subscription service, or accept a discount in return for you collecting data from their home and selling ads or something. Companies that want to do that are selling smart home devices, not the homes themselves. As others have mentioned, there isn't a ton you can do to push costs down. The unskilled labor is already cheap. The skilled labor is scarce and unionized. Material costs are set by global commodities markets. Timelines are heavily determined by external factors. It's easiest to build in the middle of nowhere, but then there is lower demand for the houses. Denser places where more people want to live tend to have most lots already developed, so now you're looking at convincing people to sell, possibly trying to get existing properties condemned, possibly rezoning, lot division, possibly needing new utilities hookups but instead of doing it in some brand-new exurb where nothing exists, you need to dig and shut down roads and sidewalks in places where people already live and work. You need permits, easements. You're disrupting things and people who don't want their lives disrupted slow you down. The skilled tradesmen who represent the major bottleneck in your workforce largely don't want to do this kind of work because it takes longer and payment is less reliable. So even in a place with relatively lax zoning where no one explicitly tries to stop you from building, you still may not be able to do it in any timely manner because you're competing for a tiny pool of laborers who can do the electrical and plumbing work and they can only be in one place at a time.
