@Frank Lo. Focus your goal for the property. If it will be a rental, the numbers have to work which often precludes the neighborhoods and value of house where my wife wants to live. On the other hand, if it will be my primary home, I am more interested in my cost to live and then look for appreciation to support a HELOC or sale later. Another way to say it is that I needed a large house with good schools and a nice neighborhood for my larger family. It wouldn't rent for enough or easily enough to financially compete with my rentals. I have forced appreciation with all the properties.
Get into a primary home with a low down payment and a 30 year loan that doesn't stretch you. Then save for the investment down payments. Your personal home is an expense not an investment. Equity in your primary home is trapped and not earning any thing because you have to sell it to put it to work. Later in life that changes somewhat.
