Buy a used mobile home for a few thousand dollars. You can pay it off in three years. Live in a trailer park until it's paid off. Then look for some property. Buy the property, put down a well and septic system and move the trailer to one side of the property. When the property is paid off, start building a small house as you can afford materials and labor. When the small house is done, sell the trailer. If the trailer was old enough, you can probably sell it for what you paid or even more. Now you have a house, and you can add on as you can afford it.

Most of the older generation did not get married and immediately buy the house of their dreams. They rented, then bought something cheap, and then traded up as they made more money. You're wanting something immediately that took older people 30 years to get. You must work your way up to it. The TV shows give people false aspirations. Sure, two professionals making huge paychecks can buy a big home at the start. But most newlyweds can't do that.
