let the cat out of the bag until I have been properly approved.  Then delicately approach the subject. You really don't want to be in a situation where you end up seeing someone and it comes back to bite you in your ass because your were not completely transparent..  

 
Another angle is that your personal info could be at stake here -your full legal name, even your occupation etc. It could impact your sphere of influence if the word gets out. I live in a Condo building myself, and very friendly with my neighbors. I particularly don't care if people find out that i see prostitutes and sugar babies, but I don't wan to advertise either. I like it to be discreet.  

 
So, I would urge you to think of the big picture.

Unless it's an issue for you, which I don't see why it would be, keep it playa and keep your mouth shut.  Obviously she's hot enough for you to reach out, then that's even more of a benefit to just mind your own business and have a provider always within adequate distance for visits.  

Why don’t you go over and ask to borrow a cup of sugar? 🤣   Joking aside, unless she becomes your ATF  and you session her frequently, I wouldn’t tell her.

...to tell her, just as she has no obligation to tell you.

If you bump into each other or connect visually at the pool etc, the burden of sharing the fact you live in the same building falls on both of you, equally.

I would keep it quite as long as you can.  As Sgt Schultz would say on Hogan's Heroes, "I know nothing!"  

Keep the information under the "Cone of Silence".  

Okay, now I have dated myself.

This possibility usually comes up under "he wanted my hotel 2 days before the meet" kind of stuff. Some Providers only give out general location info ahead of time and final specs (room number, etc.) the day of the meet or even just 10 minutes before.  In urban settings with a high density of hotels, some Providers feel safer giving out the name of Hotel A which is across the street and 20 seconds away from Hotel B, their actual location. So, is there a chance that she gave you an address (the exact same street address as your building) but might actually be hosting in another high rise to the left, right, or across the street? Did she pin down the ID of the building with more detailed info (e.g., detailed instructions: "there's a doorman at a green marble front desk; nod and ignore him; walk at a 45 degree angle to the right and there are mailboxes in a hidden alcove; cut through the alcove, turn left to get to the elevators; ..."). Is there a chance that her actual location is CLOSE to your building but NOT your building?
.
Does your potential hostess actually LIVE in the building or merely host there a few hours per month?  A shared location: Some Providers (a small group of friendly indies or a small agency) sometimes keep a luxury location that they share for their encounters. Possible in this case? That could be a good thing! ... or a bad thing.

I had some other possibilities ... to be posted later, if I have the time.

I live in the suburbs of Philly in a large upscale apartment building.  I used to go to this Asian/Korean place in Philly.  They are good, rotating girls and all get pretty nice reviews.  I decided to visit a few months ago and they told me they moved to the suburbs.  I booked an appointment, and it turns out they are not only in my building but in the apartment directly over mine.  I didn't say anything, and she didn't either when checking my ID.  

I also found a dancer at Delilah's that lives in my Buidling as well.  

Small world.

tell her you had to park two blocks away and ask her to recommend someplace closer for next time.  You accomplish a couple of things here.  First, she will not have a clue you live in the building unless you slip up by telling her about the sushi place a block away.  Sessions can go either way, and if it doesn't go well, you want to move yourself as far away as possible IN HER MIND.  There is really no good reason to ever tell her you live in the same building unless you are planning on moving in together, in which case, you could tell her, "Surprise, I just moved into the building.   This way we are close, but I won't interfere with your business."    

 
The other thing you have done with this phrase is tell her that you are the kind of guy who will repeat if the session goes well, which incentivizes her to give you her best effort.

And hope you have a great time and want to repeat. This is the ultimate in convenience. Don't blow it by scaring the shit out of her.

My thought - tell her "OMG. We both live in the same complex. I'm ok with that if you are."  

If she says Yes, then you should be ok as she has more at risk than you on outing each other.

If she says no, then she should refund your deposit as she's the one cancelling.

You gave her your name,  she did some sleuthing and found where you live.  

You can turn the table by changing your appointment to an outcall.  

LOL

DISCRETION....(every second!!!)

if I understand your post,  
1.  you’ve seen photos of her, so you know what she looks like.
2. You believe she may live in your building… but this isn’t certain
3. You’ve never seen her in or around your building.

So you cancelled your appointment and forfeited your $$ because you’re a paranoid fool.
Hate to burst your bubble, but she’s not likely to remember you … she’s probably going to forget you about 30 seconds after you walk out the door - unless you do something extraordinary - like give her her a big tip. Otherwise, you were just another xx dollars paycheck for an hour .. maybe one of 4 or 5 she did thst day.  You didn’t mean anything to her, and she wouldn’t recognize you 2 days from now if she did happen to see you.

She’s probably seen you. I still wouldn’t bring it up until she does because maybe that’s her preference.
