It feels quite ackward on the viewfinder and you lose great portion of FF sensor's ability. It's like someone buying $600 GPU with $100 celeron CPU. Sure it may work fine for that person's purpose but it's just very unbalanced.
To me, it's about the balance so that one aspect of your gears don't downsize the other.
Wouldn't an APS-C lens on a FF body actually make AF easier?
The FF Nikon cameras use the same 51-point AF sensor placement as the APS-C cameras. So if you use a APS-C lens on a FF body, all 51 points will still be used. In fact, it would cover the area better. Sure, the FF body has 51 AF points, but they're all clustered around the center, which is one of the reasons that make me frustrated with Nikon.
About that, I have no clue. What I know is that it's very difficult to spread AF points all over the frame due to how AF sensor mechanism works. To me, AF points on D3 isn't narrow at all considering how most, if not all, FF cameras are that way.
If AF points being clustered around center affects you, how about using contrast detect AF? It's slow but as you're doing real estate work, I guess the speed doesn't matter much?

The point is simply you can do it. And with sensors increasing in megapixels, that whole aspect of it gets a bit moot. It makes it easier to buy a good aps-c lens if it exists, and migrate it over, and then maybe ditch it when you're good to go. It's simply an option there for those that want to take it.
As for wanting to use an APC-S lens... well, I dunno what nikon has, but canon has a few spectacular ones. Again, FF would change the dynamics, and it might not work for you, but could be perfectly fine for someone else. Why get rid of it unless there's a specific reason other than "oh, I need a FF lens," which I see too often (the concept, not necessarily specific to lenses).
Yes, it's possible and you can do it. I'm not denying that.
I've tried mounting my girlfriend's 17-50mm on my FF body and while it was fun for that moment, I just couldn't take it. For emergency situations, I see that there's a need but I think that's where it stops.
How many people have you seen who uses APC-S lenses for their FF cameras? I haven't seen any and I think there's a reason. In the first place, why buy a FF camera if you're going to mount APC-S lenses on it? Why limit camera's potential? Would you keep a lens like Sigma 30mm f/1.4 for FF camera? Why not just go for a FF 50mm lens? Why spend big $ for the FF camera when your lens produces worse IQ than it is used on APC-S camera?
Oh well...That's just my opnion and I know you're free to do whatever you want to do. Having said that, have you ever acutally worked with APC-S lenses on FF cameras?
Read what others say and check out the samples:
(Keep it mind that the Nikon 17-55mm/f2.8 DX lens used in that sample image is one of the best, if not the very best, APC-S lenses regardless of any brands'.)
