One suggestion I'll make, however, is not to let emotions guide your decisions, especially when you're living in a unit that will eventually become a rental or a flip--unless you make the decision consciously and are willing to, for example, spend an extra $1000 to tile an apartment bathtub surround because you really want to have tile while you live there, knowing that you won't recoup your investment as a rental.  

If needed you can always throw an oven in there while in escrow.That's the sort of property where you get the best of both worlds -- potential for a crap ton of sweat equity, but you get to dodge hard money eating into your rehab budget.
