The OP said they already had affordable options. He just didn’t want to post the names or net costs. Implying that had the thread stayed open “one of the most important parts of the process for low SES students” might have become available is misleading. You may have hoped to convince the OP to give details, but that doesn’t mean he would have posted them. He was pretty clear that he didn’t want to provide those details.
How much a family is willing to pay matters, but it’s not the most important stat. Where the money comes from is. The OP can pay $2-5k, but his son has a ~$16-20k budget due to a combination of Pell, student loans, summer work earnings, and family contribution. It’s misleading to tell other low income families that you found several residential options, and imply that they can too if they only cast a broad enough net, without mentioning where the aid is coming from. Unless they’re also eligible for full Pell and have parents who contribute ~$5k their results aren’t likely to be similar.
The problem with threads that drop hints but neglect to clarify comments is that they tend to spread misinformation. OP posted just enough information for low stats/low income kids to think that residential college is a real possibility. It sounds like OP expects to have a range of affordable options (in state, OOS, publics, privates, LACs), but most low income kids won’t. They don’t have parents who can dig up $5k/year. Or they only get a small Pell Grant and that extra few thousand is more of a gap than they can close. Or they’re from a state like ours where even a full Pell Grant is swallowed up by state aid (a student who gets full Pell gets $6k subtracted from their state aid). I was a low income student so I get it. But many low income families who are new to the process might not.
