Anyway, you have some leverage as the buyer, but here are my thoughts.
1. Negotiate whatever amount you can get from the seller.
2. The actual eventual cost of the bathroom repairs is not as important as what another buyer would pay for the same house in the same condition.
If the house were on the open market, would somebody pay more than you are paying for the house ?
Is it in a high-demand area ?
If you are getting a sweet deal, then use this damage as leverage, but don’t lose out on a sweet deal over $10k. You may not get what it takes to repair the bathroom, but if your overall price you paid minus whatever seller concessions you can get is worth making the deal…. then make the deal.
