The 70% Rule Explained: How to Calculate Maximum Purchase Price
The 70% rule is the most widely used formula in fix-and-flip investing. Learn how it works, when to use it, and when to break it.
Understanding how buyers think and feel when shopping for a home helps you design renovations that sell.
Buyers don't make purely rational decisions when purchasing a home. Emotion drives the initial connection, and logic justifies it afterward. Understanding buyer psychology helps you design renovations and marketing that trigger both responses.
The first impression is formed in 7–10 seconds. When a buyer pulls up to your property (or views the first listing photo), they form an instant emotional response that colors everything they see afterward. This is why curb appeal and listing photos are disproportionately important — they set the emotional baseline for the entire viewing experience.
Buyers evaluate spaces based on how they imagine living there. Staging helps because it provides visual cues for daily life — a dining table set for a meal, a reading nook with a lamp and book, a patio with comfortable seating. Empty rooms force buyers to do mental work that many can't or won't do.
Loss aversion is stronger than gain anticipation. Buyers fear making a bad decision more than they desire a great deal. Address this by providing inspection reports, renovation documentation, and warranty information that reduces perceived risk. A home warranty ($400–$600) is a small cost that provides significant buyer comfort.
Anchoring effects influence price perception. If competing homes are priced higher, your slightly lower price feels like a great value — even if your home would feel expensive in isolation. Strategic pricing relative to competition leverages this cognitive bias.
The endowment effect means buyers who mentally commit to your property (imagining their furniture, planning their garden) feel a sense of ownership before the offer. Open houses, long showing appointments, and encouraging buyers to explore at their own pace all increase mental commitment.
Design choices should appeal to the broadest possible buyer pool. Neutral doesn't mean boring — it means your design choices don't exclude any significant buyer segment. Bold personal choices (bright paint colors, unusual tile patterns, niche fixtures) narrow your buyer pool and extend your days on market.
