Live-in house flipping

[Account Closed]

We're selling our home and want to use the cash to invest in a small house to flip. So, if you live in a house for 6 months, fix it up, and sell it- it's my understanding that we will have to pay the short-term capital gain tax. But what if we keep doing it every 6-7 months? Will the IRS have a problem with that? Will we be considered a dealer even if we're living in it? Also would we need to have an income outside of doing that?
