Action Items

  • No explicit action items assigned during the session.

Three Rules for Determining ARV

  • Only use comparable sales (comps) that are similar in key features such as home style, square footage, lot size, bedrooms, bathrooms, and garage.
  • Focus on recently sold comps rather than current listings, prioritizing the most recent sales within 90 days and extending up to 120 days if necessary.
  • Select comps close in proximity—ideally within the same neighborhood and starting with three to five nearby streets; avoid comps from different neighborhoods, even if close by.

Five Tips and Mistakes to Avoid

  • Obtain at least 5–6 relevant comps that meet the similarity, recency, and proximity criteria.
  • Remain objective and unbiased—choose the most relevant comps, even if they support a lower ARV.
  • Do not estimate ARV if there are no relevant comps; lack of comps means an accurate ARV cannot be determined.
  • Exclude distressed property sales; use comps that reflect fully repaired, move-in-ready homes.
  • Avoid speculative ARV calculations based on projected appreciation—use only actual sold data.

Four-Step ARV Calculation Process

  • Step 1: Use online tools like Redfin, Zillow, Trulia, or Realtor.com to search the subject property’s address and filter for recent, similar sold homes.
  • Step 2: Calculate the price per square foot for each relevant comp by dividing the sold price by the property’s square footage.
  • Step 3: Compute the average price per square foot from all selected comps.
  • Step 4: Multiply the average price per square foot by the subject property’s size to determine its estimated ARV.

Decisions

  • Recommended calculating ARV independently (not relying solely on agents) — Doing so ensures maximum accuracy and self-reliance, leading to safer and more profitable flipping decisions.
