No rent roll and no lease agreements

[Frank Agyeman-Duah]

I have agreed with a seller on an offer price for a triplex which will be my first REI. According to the seller's agent, the first tenant has lived there for 16 years, second tenant 6 years and third tenant 6 months. When i requested to see the leases and the rent roll i was told seller has no such records but receives the total rent in his account every month. Need advise on this before i close the deal.
