Equity in new construction

[Aaron Anderson]

Ok this is a newbie question. I am looking at build on your lot builders Adair and HiLine. They state that you can get close to a zero down construction loan and that 90% of the time once the home is complete/appeased the newly constructed home has 20% or more equity. (I am skeptical about this) however this brings up another question which I have yet to have answered. If you construct or buy a home that have 20% or more equity in the property and you go to finance it. Will the bank still require some sort of down payment even though the 20% equity is already technically met. Any help on this would be great.
