Not weird at all. But I'd make sure it doesn't really get to be a habit of his to expect a cheap date all the time and not expect to take you out on the town on his expense sometimes.
Dick
This kind of invitation usually is expected to include sex and an overnight. Not weird at all, if you know him well enough to give him your address. Actually, kind of optimal! You can combine all the elements of the first three or so dates in one evening and night.

Not wise if this is your first meeting. He could be a serial rapist. Best to meet for coffee first to check him out and his references to make sure he is safe.
stranger
Yes it is weird , and unsafe
Foofa
Not just weird bu incredibly dangerous. You don't know this person or what he's capable of. Even if he doesn't turn out to be a serial killer/rapist he could just be a dud that you'd like to be able to walk away from (which won't be possible if he knows where you live). This is why the cardinal rule of using the internet to make initial contact is that the first three dates MUST be conducted in public places. This is just for safety.
