I know that 20% down on a house is a good rule to put as a down payment on a house. What I don't know, however, is how much more is typically a good idea to have beyond that. Since this will factor into the price of the house I should get, it'd be good to know.
What I'm curious about are things like closing costs, the fact that I should still have 6 months of living expenses saved up, how much I should have aside for house repairs that could pop up soon after buying, etc. What are your experiences for money needed BEYOND the 20% down payment in the short-term (~1 year after buying a house)?
This is driven by a fear that I would buy the house, exhausting most of my savings, and then get popped by something I'll need the money for, so any guidance is appreciated. Let's do the math using a $100,000 house with a $20,000 down payment for any examples to keep it easy.
