If you are going to apply for a loan to buy a house, a smart way to buy a house is to save at least 25% of the market sale price in cash to cover the down payment, closing costs, and moving fees. This means the amount of money that you are starting to save is depend on the price of your dream house. However, since the market is volatile, saving approximately 20 percent of the total price will save you from a very difficult process. Since you need to pay some extra fees as well while buying a house such as title deeds, taxes, etc.
