What ARV Means and How to Run the Numbers on a Houston Flip

ARV in plain language

After-repair value, or ARV, is an opinion of what a property might sell for after a defined renovation is completed. It is not today’s as-is value and it is not a promise. A useful ARV begins with a specific finished condition: layout, bedrooms, bathrooms, materials, systems, and curb appeal. If the planned finish differs from the comparison properties, the estimate needs adjustment. Investors should produce their own view rather than relying on a marketing number.

Choosing comparable sales

Look first for recent arm’s-length sales near the subject property. Favor the same subdivision or a truly comparable competing area, similar square footage, construction, age, lot characteristics, school assignment, and flood exposure. Compare renovated homes with the finish level you can realistically deliver. Avoid selecting only the highest sales. Explain why each comparable belongs in the set and how differences affect the conclusion. An agent or appraiser can help, but the buying decision remains yours.

A hypothetical worked example

For illustration only, suppose a buyer estimates a finished value of $300,000, a purchase of $170,000, repairs of $55,000, and combined closing, financing, holding, and selling costs of $35,000. The illustrated margin is $300,000 minus $170,000 minus $55,000 minus $35,000, or $40,000 before taxes and surprises. These round numbers are hypothetical, not a Houston market claim or project quote. Changing the timeline, resale price, or repair scope can quickly change the result.

The 70 percent rule

Some investors use the 70 percent rule as a quick screening tool: roughly seventy percent of ARV, minus repairs, suggests a maximum purchase target. It is only a rule of thumb, not a guarantee or valuation method. It can be too conservative or too aggressive depending on financing, holding time, resale costs, project complexity, neighborhood, and required return. Build a complete budget after the first screen. Never replace line-item underwriting with one formula.

Houston checks that can change a budget

Review mapped flood zones, prior flooding, drainage patterns, and elevation information where relevant. Foundation movement, expansive soils, older supply or drain lines, aging electrical systems, roof condition, and HVAC capacity can materially affect scope. Confirm permit needs and whether additions were permitted. Read HOA documents and deed restrictions before assuming a rental, addition, garage conversion, or other plan is allowed. Repair ranges are planning inputs, never contractor quotes.

Protect the margin

Use written scopes, obtain appropriate inspections and bids, add a contingency, and model delays. Separate required repairs from optional upgrades. Revisit ARV whenever the planned finish changes. Browse current deals and use your free account to review available numbers, but verify them independently. General education only—not legal, tax, or financial advice. Texas closing details vary, so confirm your situation with your own title company and attorney.

Turn the estimate into a decision range

A single ARV can create false precision, so consider a reasonable low, expected, and high outcome. Run the complete project budget against each one. Do the same for repairs and timeline: a base scope, a more demanding scope, and a delayed completion. The low-value, higher-cost case shows whether the project still has room for ordinary surprises. Include costs that are easy to overlook, such as initial cleanup, utility activation, lawn care, temporary security, lender draws, inspections, permits, staging, and buyer-requested repairs at resale. Separate cash needed at closing from total project capital so the funding plan is realistic. Before offering, write the few assumptions that most affect the result and decide how each will be verified. After contractor access or inspection, update the worksheet rather than defending the first estimate. ARV is most useful as one tested input in a complete decision, not as a headline that makes the decision for you. The objective is not to predict perfectly; it is to understand the conditions under which the project can and cannot meet your goals.

When selecting comparable sales, explain why each property belongs in the analysis. Note distance, subdivision boundaries, school zones, major roads, flood exposure, lot utility, living area, age, construction type, renovation quality, garages, pools, and sale date. A nearby sale can still be a weak comparison if buyers view it as a different product. Avoid averaging unlike homes merely because a search tool returned them together. Give more weight to the most similar verified transactions, and investigate unusual prices rather than automatically including them. If few good sales exist, widen the search carefully and increase the uncertainty range. Keep screenshots or source notes so an appraiser, partner, lender, or future version of you can understand the reasoning behind the estimate.
