Final answer:
The maximum limit for single-family homes in 2015 isn't provided in the reference material, but factors such as market demand, mortgage financing, and economic conditions likely influenced the upper limits for these homes.
Step-by-step explanation:
Factors Influencing Upper Limits for Single-Family Homes in 2015
The maximum limit allowed for most single-family homes in 2015 isn't explicitly stated in the provided reference, which mostly details the trajectory of home sales and the state of new home construction up to that year. However, by analyzing the historical context provided, we can deduce factors that influenced the upper limits for these homes around that time. The period up to 2006 saw a steady rise in the number of new single-family houses sold, which then dropped dramatically from 2006 to 2011, and began to recover thereafter.
During the housing market boom, from 1990 to 2006, there was an increase in homeownership rates from 64% to over 69%, and new single-family home sales peaked in 2005. This was also a time when mortgage values tripled, making housing more accessible and considered a safe financial investment. From these trends, we can infer that the factors influencing upper limits were likely tied to market demand, availability of mortgage financing, and general economic conditions that affected home values and construction costs.
