Taxes on fix and flips

[Mike Chira]

Hi everyone, I'm a new investor in Augusta Ga... I just bought my first fix and flip property at foreclosure. I will have the closing in a week and then I'll start the rehab. 

My end goal is to buy and hold multi family rentals. So I wanna fix and flip and invest profits into multi family rentals.

My question is, how will this work on taxes? If let's say I do 5 flips this year and I make 20k profit on each...then in December I take that 100k profits and put everything down on a 400k multi family... Will I still have to pay the short term capital gain taxes on the 100k ? 

I did a lot of research but couldn't find anything specific on this. 

I understand that I can do cash out refi or HELOC, and that it something I also consider for the future. Or I can rent it for 1 year and then sell it and do a 1031 exchange, but for my first year I'd rather just fix and flip.
