it's cliche, but once you know, you know.
don't be afraid to buy less than you're approved for. Future you will thank you.
Don't buy wood siding. I've done that twice and should have learned after the first time.
Look at the age of the heater, a/c, water heater, etc. Those will need replaced and will cost a ton when the time comes.
Save $4,000 to buy furniture, blinds, TV, etc. Nothing looks worse than a freshly painted living room with a single tv and couch. Make your house your home.
A house doesn't define you. It's exciting to think about decorating and the change in your life, but after a month it just becomes life. Houses come and go. Don't rush it but don't drag your feet when you find the one you like. The perfect house doesn't exist.
