It seems that the information regarding the prices of affordable houses in Kenya is not directly available from my function response. However, I can provide you with general insights based on available knowledge.

In Kenya, the prices of affordable housing can vary significantly depending on the location and the specifications of the properties. Typically, affordable housing projects may offer units in the price range of:

1. Urban Areas: In cities like Nairobi and Mombasa, affordable housing prices can range from KSh 3 million to KSh 6 million for smaller units or apartments.

2. Suburban and Rural Areas: In less urbanized regions, the prices are generally lower, ranging from KSh 1.5 million to KSh 4 million.

3. Government and Private Initiatives: There are various government-led initiatives aimed at increasing the availability of affordable housing, which can sometimes offer subsidized prices.

For the most current and specific information, including any new projects or changes in the market, it’s best to consult local real estate agencies or property listing websites.
