The best way? Keep saving until you have more than the full value.
Besides that are you sure you want to spend ALL your cash on a house? Will you suffice if you lose your job the next day? Don't forget home insurance, electricity, water, etc on top of your usual expenses.
You're much safer to have a $800 in mortgage payments and 100k in savings. Rather than zero mortgage payments and zero in savings. That's just terrible planning. Catch my drift?
Think of real estate as a nest. You never put all your money in one nest.
