What happens when a house depreciates? How do I prevent that?

[Samuel Chua]

Hi guys, I am interested in buy and hold properties and was wondering what happens if a house depreciates. What are the factors that would cause a house to depreciate? On that note, what should I do when my house depreciates? This is because when the house depreciates, all my cash flow becomes pointless and I might lose money even. Thanks!
