And make sure you have a substantial amount saved up. I'm looking into buying a house now and they want a minimum of 3% plus closing costs in your bank account for at least 2 months. They want to make sure you aren't just getting all the down payment as a gift. I say go for 2x your salary and it should be cake to afford. Credit unions are supposed to be great for borrowing money, but I guess it depends if they do home loans. Here's a few points that I will be asking the next person I interview about a loan.
1. Interest rate
2. Any points on the loan?
3. What are standard closing cost fees? (some charge a nominal rate then add points if any)
4. Ask for different options, like putting more down and getting better rate or no points. Worth it in the long run to get a loan from mommy or daddy that doesn't cost you 1000% over 30 years.
Another thing, when you negotiate with the seller try to get them to pay closing costs. And even look for a real estate agent that is selling the house so you can negotiate their cut better. 2 real estate agents have to split the costs, which may drive them up higher.
