As it stands right now, you won't get any Player House, other than one you take over. You only get the one on Megaton by saving it, and you get the one in Tenpenny by blowing up Megaton.
If you don't want the negative Karma, then try to disarm the bomb (I believe you can do that even if you set it to blow up at first)
Otherwise, load a save from before you set the bomb to blow up, then kill Burke, then disarm the bomb.
You can kill Burke anytime you want to. I don't even talk to him anymore, I just walk in and shoot him outright as soon as he beckons me over.
