I agree with Ann Ryan below.
Come on now, how does such an experienced buyer get shafted to this extent?
Were you trying to save $800.00? (350.00 in home inspection and 450.00 on an appraisal)
Did you not want to buy a rental property warranty for $550?
There has to be more to this story as I'd say I'd trust about 95% of these FL realtors. Not that I care for that many of them, but from dealing with them all over the state, the ones who are still in the business are at least pretty honest and operate with ingregrity.
Sorry to hear about your experience. You have possible recourse in two areas. One is the Florida Department of Business Regulation as REALTORs are licensed in the state. Lodge a complaint if you can substantiate your claim at the same time contacting the agent's broker. The second is to hire a Florida real estate attorney to see what legal actions you may have against the seller and/or the agency representing the seller.
As for your "why" question. This is a hard one as I certainly wouldn't want to bite the hand that feeds me. In today's social media world, something like this could go viral and there goes the business.
All the best
