Easy way to save money when selling a home is to just sell it yourself. Real estate agents are, imho, one of the most useless professions. All you need is a real estate attorney, which you’d need one anyway.
Like many things you can do everything yourself, or contract to others to do the things you are not good at, or don't have time for. Arguing realtors are useless is like saying accountants are useless, or lawyers are useless. I also did not re-roof my house. But of course you could get terrible accountants, lawyers or roofers, and you could possibly be terrible at stuff yourself. Some people think programmers are useless and some are, but that's not sufficient to try writing it yourself if you aren't one.
Sure, because you (or your agent) managed to sell 10% more than asking price.
Try re-evaluating this 6% if all offers were 85-90% of asking price, and confirm that it is not really that much.
A good agent (as opposed to a bad one) will help (a lot) in a number of other things (bureaucracy, managing and dealing with the details, counsel - if needed - about other professionals such as lawyers and technicians, possibly help in finding a suitable contractor for renovation works, and similar) but they won't be able to raise or lower the price sensibly, the price is mainly due to the market (locally and at that exact moment).
And is the inspection done after, by the buyer?? Why isn't it done by the seller and included in the ad? That's mandatory here. Sounds like a recipe for disaster and conflicts.
