In my opinion, the majority of the country is hot not just Houston.
In response to your question, "When can we expect the market to favor the buyers?", there are only 3 main criteria to trigger a buyer's market.
1) Excess supply of housing - Once Covid hit, construction grinded to a halt, this resulted in a short supply of homes coming online. Activity is back up now, but with the astronomical rise in material costs (lumber, appliances, A/C unit shortage) I don't see an uptick in supply without an uptick in prices.
2) Increased interest rates - Rates are at record lows and the government already announced it would stay this way at least for the next 3 years and choose to average out inflation in the future to balance it. Therefore this is not happening.
3) Low Demand - This is clearly not happening as demand for SFR are spiking, especially in the suburbs of Houston as people are trying to avoid COVID and urban density. This will probably not happen in the forseeable future in Houston.
In short, I don't see anything that can trigger a cool down into a buyer's market for single family housing.
