Investors & landlords

Thanks so much for the reply! So, this brings the question - if I am supposed to supply the owners of those properties with copies of the 1099s issued to the vendors how does it work if the vendor did work at multiple properties owned by different individuals? Especially if the amounts per property fall under the $600 threshold. Do  I only issue 1099s  when the vendor has $600 or more billed to a given property? Do I issue the vendor multiple 1099s - one for each property? I keep receipts and supply each owner with a year end accounting of expenses.
