like others have said, if you make 80k a year and have had 25k in debt that you couldnt pay off in 2 years... thats pretty bad money management.
the second point is there are many ancillary costs to home purchase. with 15k down closing costs which can range into the 5-10k if you add points to the mortgage is not going to leave you with much of a downpayment, leading to PMI or a secondary mortgage at a higher interest rate.
not only do you have closing costs, now you have 5-15k furnishing your home, especially if you're doing this with your woman who will want nicer things. that doesnt count the added costs of buying a lawnmower, trimmer, snow shovel/blower, etc for maintaining the outside.
what are you going to do if you plunk the cash down for your home, still have the cc debt, and then your car breaks down? hit the cc's for more?
are you saving for your retirement? plug all of this into the larger equation and see if your management skills are up to the task.
that said, everyone has said the same thing but you'll likely do what you want anyway. its like having your mom tell you that you should have done something when you were a kid but you didnt think she knew squat and you did it your own way. learned then didnt you? i guess you'll learn now too 8)
