It's not wrong but it's risky. Since both of you are meeting for the first time, it would be ideal and safer to meet in a neutral ground other than the person's home. Beside, you can't truly tell who that person is. Most people have different image online and different image in real life. Meeting someone you don't know before for the first time in his place is very risky.
Most people have been taken advantage of through such meeting. What if you don't like the person in life, how would you retreat. If you meeting in an open place like an eatery, you can easily walk away if things fall short of what you expected or he/she tried to take advantage of you. But in his/her place, you can't walk away easily should things fall short of what you expected.
Meeting in a public place for the first time is ideal and safer.
