In all seriousness, if yours was, for example, the first property a realtor got me to look at only by failing to give me what you consider "minor details" beforehand, after I'd turned around and left immediately without bothering to look at the second floor upon seeing the "construction zone" (if not the papered-over windows alone!), I'd stop answering or returning their phone calls and email. And I'd probably leave a less-than-flattering review of them (and certainly your rental) on Yelp or whatever online resource(s) it might be listed on. Not only do realtors not want to "waste time" (sometimes excessively so, given that showing properties is after all what they get paid to do), good ones don't want to get a reputation for trying to pull fast ones on their clients. Rational renters don't expect realtors to be their "best friends", but there are limits to what they expect to have to "grill" realtors and potential landlords about and/or figure out for themselves, and those limits are heavily tied to the housing market in your area. In tight and/or lower-cost markets, people normally expect less from realtors and landlords, but obviously the higher the rents and the more choices potential renters have, the pickier they can afford to be about whom they deal with and the sort of shenanigans they're willing to put up with.
And do I assume correctly you'll want a tenant who's employed full-time? That means they're busy during the day, too and will probably get extremely pissed off at a realtor who tries to drag them around to rentals they wouldn't dream of considering for obvious reasons - even less significant ones than major construction on the first floor of a two-floor/two apartment house - that the realtor "doesn't see any reason" to "disclose" beforehand. (And yes, full dry-walling and tiling is "major" as far as most people are concerned.)
As for the seeping basement, if a treadmill is the sort of "personal property" that "requires protection" to the point where you feel the need to put that in the lease to cover your own ass, and if the potential tenant specifically asks about putting one down there, then not telling them the basement is unsuitable for it may stop short of being downright "dishonest", but it certainly is shady. Especially since it appears that you'd object to them being told about it at all before they figure it out for themselves from whatever language you've inserted "somewhere" in a multipage lease, only after they've presumably looked at, and possibly passed on, more suitable rentals, have gone through the whole approval process, and are about to "sign on the dotted line".
PS: The more you write, the shadier that basement sounds altogether. How suitable is
any area as "storage space" at all - except maybe for outdoor furniture or scuba gear

- if anything someone puts there "requires protection" from otherwise-probable water or moisture damage? And must I really point out that even your choice of the legalistic word "disclosure" (versus "mention", "note", etc) itself suggests a certain shadiness? As in, doing the absolute minimum necessary to protect yourself from actual legal liability rather than looking to avoid renting the place to someone whose "disclosed" needs you
know it affirmatively fails to meet in the first place? And who, I'll also point out, would therefore unlikely be satisfied, let alone happy, with the situation when they later discover it? Even from the standpoint of your own self-interest, that seems short-sighted, since such a tenant wouldn't exactly be terribly well disposed to dealing with
you on anything but a purely "legalistic", adversarial basis.. And unless you're quite sure you'll always be able to stick to the exact letter of the law and your lease (something most individual landlords who don't use management companies, especially those who are otherwise employed full-time, often find difficult), you might not wind up being very happy about that yourself..
