I think the live in flip is a great concept, but if you're looking at a 35k gain, it's probably not worth the headache. As Mindy Jensen mentioned, when you sell you'll have realtor commissions, plus regular closing costs. Additionally a buyer may want concessions on items even if the property is turn key. So you may give up 2 years of your life for 5k.
We're in the middle of our third live in flip, we bought the home, and were able to get it livable before moving in, however it was a year before we finished the second bathroom. (Not fun for a family of 4 to share 1 bathroom). So be prepared, it's a lot different when you have to go without A/C in the middle of July in your own home, than your flip property having to do without for 2 days while it's getting installed.
A good hybrid may be to purchase the undervalued asset, complete the repairs to increase the value and leverage a line of credit against the property to move on to the next project. You could then move out and make the property a rental and have the tenants pay down the debt, if the numbers made sense.
