The two plans are not that far apart. For some people like myself I would decide based on the hassle and certainty rather than the slight differences in financing costs.
You are allowed to sell and not pay taxes on X gains (250K or 500K depending on single or a married couple) once every 5 years. You have to have lived in the home 2 out of 5 years unless there was a 1031 into the home you are calling your residence. Hence there is a 3 year window for you to sell the home you had lived in.
As you are posting to an investment board many smaller investors build their portfolio by never selling their prior residence. Not exactly the best idea from a tax point of view if there is a lot of gain. It does say on the transaction costs. You also know the present home so you know deeply the condition, maintenance record, etc. Given the tax code presently it might be best to sell and capture the funds after tax (zero in this case it sounds like) and then consider an investment if you want to own a rental.
BTW - you could refi your present home and then move to a new home later. Only do this is you were going to continue to hold the present home. You could lock the rate compared to a HELOC.
