Whoa...a realtor who does sell condos! Stop the presses.
Name ONE SINGLE CONDO ASSOCIATION that won't let you remodel the bathroom. Seriously, condo docs have rules, condo docs have regulations but what condo docs DO NOT HAVE is "laws that must be followed after purchasing". Inside the cubicle of air you buy, you can remodel darn near anything just as long as you don't make structural changes. There are plenty of goofy things in condo docs but if there is a prohibition on "bathroom remodels" or switching one kind of a tub for another, I will humbly apologize....of course, we'll need to see it. Otherwise, let's stick to the facts, ma'am.
