Three Primary Considerations of a Civil Case:
1. Did someone do something wrong? This is liability. Here the seller should have disclosed multiple issues that they did not. Flooding onto the property. Water penetration. Garage is built into the utility easement at the rear of the property. Probably others. So you probably have liability. But when I see a large commercial structure behind you, I start to question whether they might be contributing to your problem and be the reason water collects in your garage. Doesn’t excuse the non-disclosure by the seller, but could be an alternative if the seller is judgment proof.
2. The next question is what harm has it caused you? Or, in other words, how much will it cost you to fix? That could be relatively simple. But it could cost tens of thousands of dollars. If it is small and going to take $1400 to prevent, you should not hire an attorney because the money is better spent on the problem. You can still ask the seller to compensate you, but it is not worth your money and time to hire an attorney for that.
3. Can the defendant pay the judgment when you do win? If the seller is older, has no income, their only income is their job, or any number of other reasons why they don’t have money, it is not worth it to proceed against them. You can pay any lawyer to represent you regardless of the probable outcome. I represent clients on hybrid contingency fees so if I do not think I can recover against the defendant, I will not take your retainer money.
