<p>My main issue with the OP’s step-son would be the attitude – that he resents being told he should be paying rent. </p>
<p>IMO, if he doesn’t like the deal, he can be encouraged to look for a better one.

DISCLAIMER:**
Both my kids lived at home rent-free for periods after undergrad. D was working full-time, paying off her student loans and an old car she bought from us, and saving for grad school. When she went to grad school she lived on her own, paid all her own grad school expenses (although was funded so had no tuition and was a TA), and then after grad school got a new job in her new city. But she never paid us rent.</p>
<p>S, college grad '12, now lives with us. He is working full-time in his field and paying off his student loans (only the Staffords, like his sis) at double the expected rate and also paying us parents $500/month for the new but modest car we bought for him. (Basically, he got his car loan at the bank of mom and dad.) He is very helpful around the house – takes care of trash, does some landscaping, will cook, shop, and bails me out when I have computer trouble. </p>
<p>I would rather he expedite payment of his loans than pay us rent. He will buy groceries and occasionally takes us parents out to dinner to show his appreciation. When I cook for him he thanks me. (And when he cooks for me I thank him.) His GF is in vet school and will have heavy loans when she finishes, so I encourage him to save now while he has the opportunity, so they will have a cushion when they hitch up (presumably – dating seven years).</p>
<p>We allow him to have friends stay in our guest room when they are in town visiting and we have no curfew but he tends to lead a simple, low key life. He shares his plans with us and we are fine with whatever he is doing. Our only issue is that I sometimes nag him to clean up after himself in the kitchen and bathroom and to keep his room reasonably decent. I tell him how fortunate he is to have such a good setup but feel it would be wasteful for him to get his own place at this point. (GF’s grad school is five hours away.)</p>
<p>Back on topic:</p>
<p>OP’s situation is more challenging as she is a step-parent and the young man seems to have an entitlement issue. Those who say the dad should take command here are absolutely right IMO. Stepmom needs to step aside, as she seems to be doing, but I appreciate that can be hard as she lives with the situation. </p>
<p>The attitude is the main problem I see – if his attitude underwent a revision, I suspect the other issues would be helped. Perhaps a month of couch surfing would be good attitude rehab.</p>
<p>Hope progress and a mutually satisfying resolution can occur.</p>
