How do you verify income on a property (rent rolls, leases?)

[Julius Dixon]

Hey guys,

I'm reading a REI book and it is talking about verifying the income on a property before making a purchase. This seems obvious but how this is done more specifically and what prevents a seller from inflating numbers, and how can you independently verify current rent rates and occupancy? Is this a buyer beware type of situation, or are sellers contractually bound not to inflate their numbers?

Thanks,

Julius
