As for going back to renting when you move - I think you should reconsider. You'll hopefully be in a position where you can move somewhere that your housing dollars go further, and have some equity in your current home. A condo or townhouse can relieved you of a lot of the burden of exterior maintenance, and then you don't have to worry about the landlord selling or having to move for other reasons. Also - having a paid-off home by the time you retire can really ease your retirement finances.
