When my wife and I first started out investing, we lived in our flips.
It can be a great way to get a house with a low or no downpayment, also if it takes time to sell, it is not a big deal.
The big thing to remember with flips is they usually take longer to sell than you expect. A lot of people leave out some of the carrying cost details when they say how much they make.
That being said, the bigger money is usually made if you can change the use of the property, either by re-zoning, sub-dividing or adding units. It may not be possible to live in a property that is having extensive work.
When we did not have kids, it was pretty good, as long as you are ok with the following:
You will be living in a construction zone, that does not sound like a big deal, but I can remember my wife and I thinking after our third project, that we would love to buy a house that did not need any work. It is just irritating living with dust, and debris, plus waking up with a contractor in your room.
You may have to leave on a moments notice when you list. One project we had a full price offer, however, the condition was we had to be out in two weeks.
When you have kids it is harder, one of the motivations to switch to buy and hold investing, is that moving with kids is tough. Having a house for sale with kids, trying to make it look like a museum for showings is tough (not to sound like one of "those" parents).
In summary, if you are single, or a couple, I say live in your flips as long as you can stand it.
If you have kids, it will depend on what your full-time work schedule is like.
I hope this helps,
