If I assume you have a salary of say $60k, then the offer is $7k and 4%, so approaching $10k gross, maybe $500 a month net extra after tax when you already have say $3500. On that basis, no, I would NOT take it, I think there are a range of issues working in an office (politics, noise, getting interrupted/productivity, inconvenience, personal space, restricted daily routine, more politics, lost commuting time) and I would not consider $500 a month sufficient to accept them.
