These seem like useful services, but the seller paid at least 3% of the home value towards them. Wouldn't you have rather just had that as cash instead?
I don't expect their realtor to act in my best interest if so. Our goals aren't aligned. I almost fell into a situation where the realtor I was choosing was the buyers representative as well, which a family member who is a realtor as well as my bank advised was a terrible idea.
If you're proposing that realtors are just half price then I don't have a problem with paying less for things :)
What if you could just buy the house for $282k and never had to have an agent? Perhaps you would have missed these issues. Or more likely you would have Googled for a robust checklist of things to look for in an inspection, and discovered them yourself.
This is a structural reimagining of things could be.
For example my house had a situation with taxes where I had to pay investor rated taxes for a year since it was held by an investor previously. That's the tax rate I see when I look at the MLS. I would have said no to the house if my realtor had not told me the way it worked, and that they would fall off the next year. I don't know that a generic list can capture that since its specific to my locale (or not, I don't know how it works in other places and that's great since I don't have to be an expert on it).
