Please I need sincere and genuine response to the above questions.

I don't think there is an "ideal age" for anyone to marry. Once you think you're ready to, then you can. As for income level, can you feed 4 mouths?

Wait till you are 40 and have enjoyed life. Before you enter what you cannot come out.

Ideal age= whenever you're prepared and ready
Income level= depends on the babe!

Anoneism: Please I need sincere and genuine response to the above questions.

-D'banj is richer than most of his age mates n yet many of them are married n he is nt..........
-Many twins dont marry same day. If they choose to, can they impregnate/ conceive same day?
-Some people were born d day u were born, many of them are dead, why are u still alive?
..........Ponder on these few.........

The Ideal age for a guy to get married is between the ages of 25 - 30. Anything earlier is considered 'too early' and anything btw 30-35 is already in the 'near-danger' zone which is late. Above 35? That's extra late.
Income level; The guy should have at least a steady source of income which is above #150,000 per month, at least a car, an apartment (one bedroom flat at least) with 2 yrs or more rent paid and a bank account that can at least cater for 3 people for 6 months if he looses his job (this will keep the house going till he gets another one)
...
But apart from all these, a guy who considers himself ready should also be ready;
1. Spriritually (to know God's choice for him.
2. Emtionally (to be able to stick to 1 alone)

With all these, I think he should do fine.
