It sounds like to me the station simply received an offer to buy KWED from the Seguin School Board. Getting an offer to buy a station, while not all that common, it is not uncommon. At the station I manage, we get the occasional 'would your owner sell?' and more infrequently 'would X dollars be in the ballpark?'. Some proceed on to the owner.
I'm not sure why a school district would want to jump in the radio business but I must assume they have a well thought out plan. Most school districts are always trying to squeeze more from every dollar. If they might be interested, perhaps leasing some time might be an option. I still have to wonder how the public would view the idea. I'd say the offer begs for several questions: Is the school district prepared to operate a radio station? What purpose and enhancement would the station offer the school district? If it is to air school sports and give kids an outlet to 'play' or learn radio, is the school district in the business of running a radio station? Would it be a financial burden? If so, could those dollars be allocated in a more vital educational purpose?
In their defense, the Mesquite Schools in Mesquite, Texas has an FM station. Several other schools across the nation do as well. In fact, that number might surprise you. I have to question if any actually throw off an income or do as much as break even. There are certain costs involved in running a station, especially one like KWED. Would ownership be a financial burden? If so, and budgets got tighter, a radio station is not something that can be sold easily. In other words, you have costs that cannot be eliminated and even if a decision to sell was made, might require maintaining the station for an extended period of time until a qualified buyer is found and a deal finalized and executed.
If the School District has become angered, that is certainly no time to take on such a responsibility. I would contend if anger is the motivation, members of the board need to check their egos at the door before the next board meeting. I have seen crazy things happen in radio. Stuff you'd never believe unless you saw it unfold. But I have also seen ill fated decisions create nightmares for the group that acted crazy in their decision making. If there is such a rift, it might be best for a 3rd party to help work out a solution both parties could live with or at least offer other solutions.
If I recall, and if things have not changed, I think Guadalupe Media is a 3 station group: the AM and FM in New Braunfels and KWED, Seguin. From my understanding, none of the stations were hurting for income. The general thought is they are well run stations. $400,000 would certainly be under the actual value. I would suspect well under the 1x gross income figure.
KWED might be up for sale. We'd likely never know unless we signed a confidentiality promise with the broker offering the station. If for sale, it could be any of several stations you see 'advertised' by brokers such as 'established, profitable Texas AM in growing area' with or without an asking price.
KWED is a 'heritage' local station that has served Seguin for decades. The FM was sold many years ago and became a San Antonio player. KWED continued their full service local emphasis.
