Pitched floors on a 5-unit deal

[Peter Paxos]

Hi to the fantastic and informative BP community! I'm looking at a 5-unit property in upstate New York. During a walk through with seller and agent and there was a noticeable pitch to the floors in each of the units. What should I look for to determine if there is a concern with the integrity of the structure? I don't yet have the property under contract and did not want to spend the money on a PE. Any advice on how to proceed ? Thank you for your kind advice and assistance. Peter. Thank you for your kind advice and assistance. Peter.
