What is Karen's responsibility to Jay regarding the rent checks?

Karen’s responsibility to Jay regarding the rent checks primarily involves accounting for any money received in a timely manner. This means that she must keep accurate records of all rent payments that come in, ensuring that Jay is fully informed of the financial status related to the property. Timely accounting is crucial in property management as it helps maintain transparency and allows for effective financial planning.

By promptly accounting for the rent checks, Karen can help prevent disputes over payment discrepancies and maintain a clear financial picture of the rental operations. This responsibility reflects the fundamental duties of property managers to uphold good financial practices, ensuring that both the property owner and tenants have a clear understanding of all received funds and outstanding balances.
