My major comment would be to look for completed condo projects rather than any project that is still being developed since if you did elect to sell in the next couple of years you would not be competing with the builder whose first priority would be to sell the remainder of the project etc.
Would be please to provide a variety of condo's for you to review if you would simply send me an e-mail at firstname.lastname@example.org or call me at 608 334 1580 at your conveninence. Would be pleased to provide some additional information rather than simply a MLS listing specifications .. but again... depends on what would be convenient or close to your local family.
Believe you have a great idea about having somewhere to stay when you visit... in many ways would be easier on everyone plus providing everyone that "emotional space" that sometimes is needed.
