What Weldon Spring’s housing numbers say
About three in four renters are stretched
74% of renter households spend 30% or more of their income on rent, against 46% across Missouri. That’s despite a standard two-bedroom costing just 13% of the median household income, so renters here earn far less than the typical household. Renting ↓
About half of homes sell above asking
In September, 48% of the homes that sold went for more than the asking price and 52% went under contract within two weeks. There was about 1 month of homes for sale at that pace, against 3.4 across Missouri: 10 listings for 10 sales that month. Expect competition on well-priced homes. How fast homes sell ↓
