W-9/1099 for first flip

[Joseph Rios]

2019 Tax season is upon us and I am about to complete my first flip (hopefully closing soon). Since this is my first flip I am now (in April of 2020) just finding out about the W-9 form we need to ask contractors to fill out in order to use the payment made to them as an expense. I have receipts but now I am stuck on whether I should be asking for it now and sending the 1099 copy to the IRS. Also I bought this flip in November of 2019 and I haven't technically sold it yet so not sure what this would be classified as for year ending 2019. Any advice from experienced investors would be greatly appreciated!
