Per the link I shared earlier in this thread, California pays $1000 per adopted child per month as a base rate (with higher tiers of payments based on health needs). So, by my estimates the couple is receiving a minimum of $4000 per month (I recall there being 4 total adopted children, but someone please correct me if wrong).
For those not familiar with the area, California City is one of the lowest cost of living areas in the entire state. Zillow shows the home sold 3 months ago, presumably to the Wests, for $197,000. Assuming a standard 20% down payment and with the low interest rate environment, their monthly mortgage payment would be approximately $900 per month based on online calculators.
Were they in adoption for the money? Hard to say since we don’t know much about the couple or if they had any other jobs/businesses, but regardless they would need to put on a decent show to convince the state that they want to be adoptive parents for the right reasons. A similar show was put on at the press conference. JW mentioned in the press conference that “they were going through it”. With their kids taken by CPS, without another job, there may be no other income stream.
