Sorry for the following Contrarian advice, but you're not a 5 year old so:
The only reason to buy a personal residence (Home) is because someone is forcing you to.
Usually, this person is called your Spouse (which is Latin for someone who forces you to make horrible financial decisions then criticizes you for them endlessly:)
perhaps DON'T buy a home, just rent something affordable and invest the 20% or in your case 50% into the stock market (sp500 16.1% yearly return last 15 years, 11% last 50 years, 10% last 125 years)
remember, your RENT is your maximum monthly housing expense, but your Mortgage is your minimum or starting monthly housing cost, it always goes up from there
I've, owned 2 personal homes, 100% appreciation in 6years on #1 and in 7 years on #2, (I timed our market perfectly both times), with 20% down and very low mortgage rates, but after honestly calculating all expenses, only made about 5-6% a year "investment wise". Would have done 2-3X better in stock market, and with 1000% less grief/stress.

Also, big picture, residential RE, appreciates only at rate of inflation, on average both in US and abroad.
"Transaction prices of real estate on the Herengracht, the finest of them all, have been carefully recorded. In 1997 Dutch economist Piet Eichholtz build a price index of houses on the Herengracht with a constant quality from 1628 until 1973. This was the birth of the Herengracht Index. Eichholtz’s initial research showed that real housing prices (corrected for consumer price inflation) gradually changed over time, but were fairly equal in 1973 compared to prices in 1628."
We are currently in highest residential housing price bubble ever recorded in US history (Case-Shiller housing Index) so If you buy Cisco in Dec '99, ain't gonna go well for you, probably :)
good luck
