Question

which two trends have produced an affordability gap related to housing, resulting in homelessness for families with children

Answer 1

Expensive Materials

Step-by-step explanation:

Houses built using expensive and extremely good quality materials are more expensive than houses that aren't quite the sight for sore eyes, and aren't that good quality but still liveable, are obviously going to be more expensive. For example, a 2000 sqft house could cost 500K USD for medium quality products and materials, but that same house, but with marble, gold, and very good materials would cost probably 800K - 1.2M USD. Materials' looks aren't that important, and the quality doesn't have to be astronomical either, the home just has to be livable.
