Potential Water Issue Disclosed

[Holly Hall]

I'm considering purchasing a property in Denver. It has been disclosed that there may be a breach in the terrace water barrier that could lead to water intrusion in the unit downstairs. The seller has said he will cover repairs needed for a term of one year post-closing if an engineer hired by the building HOA determines repairs to the water barrier are needed (estimated cost $30-40k). Would such an agreement be enforceable post-closing?
