My neighbor has allowed his house to fall into disrepair and as a result, I have lost a potential buyer for my house. Can I sue for the loss?
To win a lawsuit like that, you would need to prove that your neighbor breached some obligation that he had to you specifically, and that breach led directly to the lost buyer, and a quantifiable financial loss resulted. That strikes me as a difficult set of facts to prove, but given the minimal detail I have, I can’t say for sure that the answer is no.
The best way to find out for sure is to consult with an attorney who can go over the specific details of your situation, and give you an educated opinion.
