I'm bullish on this area of the market as well but I've really struggled to find a company that is worth the time to invest in. Margins are relatively thin and growth is slowing coming out of the pandemic.
Doman's free cash flow generation was really only worth looking at during the lockdown COVID situation (2020-2022). My concerns here is that that type of housing market euphoria is highly, highly unlikely to be replicated ever.
These are not companies I"d ever buy and hold for the long-term. Their business models, razor thin margins etc don't really fit into my criteria for something I'd be comfortable buying and forgetting about.
However, I do see where you're coming from in terms of the possibility of them going up in the short/mid term because of the massive shortage of housing we have here in North America. It is certainly a thesis that could easily come true.
Have you considered possibly mitigating the risk a bit in terms of going with an ETF over selecting a couple individual equities? The iShares US Home Construction ETF (ITB) is one that has garnered a lot of attention as of late.
It trades in USD unfortunately, but is one you could look at to get exposure to 50~ homebuilding companies in the US.
