Potential problem with these conditions?

[Sam Zdrum]

From my counter offer. The seller listed these conditions on the contract.

1. Tenants will have possession for 60 days after closing.

2. Purchaser will retain $700.00 security deposit to be returned to tenants after completion of lease.

This is my first purchase with a tenant in place. Need advice from Bigger pocket family to help me be prepared for potential issues or a counter condition.

Thank you all!

Sam
