Questions investors ask about repair cost estimation

A repair-risk deal brief turns an inspection report into a buy-or-walk decision before your option period expires. It takes an inspection report, property description, or condition notes as input and returns a line-item breakdown of expected repair costs by trade — roofing, HVAC, electrical, plumbing, kitchen, bathrooms, and more — adjusted for your local market, plus MAO scenarios and a buy-or-walk recommendation. The brief gives you the numbers you need to decide whether to proceed, renegotiate, or walk away.

A full residential renovation typically costs $45,000–$120,000 depending on property size, condition, scope, and local labor market. Cosmetic-only renovations run $25,000–$55,000 for a 1,500–1,800 sq ft home at national average labor rates. Full rehabs including mechanicals (HVAC, electrical, plumbing) run $55,000–$95,000. Properties requiring structural work or in high-cost markets like Seattle or San Diego can exceed $120,000. Always apply a 15–20% contingency to your base estimate.

MAO stands for Maximum Allowable Offer — the highest price you should pay for a fix-and-flip property and still hit your target profit margin. The standard formula is: MAO = (ARV × 70%) − Rehab Costs. For example, if the after-repair value is $350,000 and rehab costs $75,000, the MAO is ($350,000 × 0.70) − $75,000 = $170,000. The 70% multiplier leaves room for closing costs, financing, holding costs, and profit. Experienced investors run three MAO scenarios — conservative (65%), standard (70%), and aggressive (75%).

The 70% rule says you should pay no more than 70% of the after-repair value (ARV) minus your estimated repair costs. It leaves approximately 30% of the ARV for closing costs (2–3%), financing (7–10% annualized), selling costs (6–8%), and profit (12–17%). The rule is a screening shortcut — if a property cannot pass the 70% test, it rarely works when you run the full numbers. If it passes, run the full cost analysis before making an offer.

ARV is the estimated market value of a property after all planned renovations are completed. It is calculated by analyzing comparable sales of renovated, similar properties in the same neighborhood — typically within 0.5 miles, similar square footage and bedroom count, sold within 90 days. ARV is not the list price, not the current as-is value, and not the purchase price — it is the projected exit price after renovation. ARV is the foundation of every fix-and-flip deal analysis because the MAO formula starts with it.

Scopebase repair-cost estimates are designed for pre-offer buy-or-walk decisions. Pre-inspection outputs should be treated as broad ranges, typically ±30–50% depending on input quality. Complete inspection reports, contractor bids, and actuals tighten the number. Scopebase estimates are not contractor bids; they tell you whether a deal deserves one.

No. Scopebase is decision-support software, not a contractor bid, a professional inspection, an appraisal, or a lender commitment. It produces a pre-inspection repair-risk estimate to help you decide whether to make an offer, renegotiate, or walk. A contractor bid is a priced commitment to perform specific work after a site visit; Scopebase tells you whether a property is worth getting that bid. Always confirm scope and pricing with licensed contractors and a professional inspection before closing.

Yes. You can upload a home or mechanical inspection report as a PDF (or paste the text) and Scopebase extracts the noted deficiencies, maps them to repair line items by trade, and prices them for your local market. A complete inspection report produces the most reliable output. Scanned, image-only PDFs may extract less detail. Scopebase reads and summarizes the report to build an estimate — it does not replace the inspection itself.

Treat the estimate as a screening range, then verify before you commit capital: (1) order a professional inspection to confirm hidden conditions, (2) get written bids from licensed contractors for the largest line items, (3) sanity-check the ARV against recent renovated comps, and (4) keep the built-in contingency in your MAO. Confidence varies by input quality — items flagged for on-site verification are exactly where a contractor bid changes the number most. Scopebase is the first screen, not the final budget.

Scopebase can generate an estimate from an inspection report (PDF or text), a property description with condition notes, or a combination of both. A full inspection report covering HVAC, electrical, plumbing, roof, structure, interior, and exterior produces the most accurate output. A general description produces a wider cost range but is still useful for initial screening. You can also specify the property address to get local labor cost adjustments automatically.

Renovation costs fall into four categories: (1) Structural — foundation, framing, load-bearing walls, roof structure; highest risk and widest cost uncertainty. (2) Mechanical — HVAC, electrical, plumbing; expensive because they are required for habitability and lender financing. (3) Cosmetic — kitchen, bathrooms, flooring, paint; most predictable, primarily driven by finish level. (4) Exterior — roof covering, siding, windows, gutters; often underestimated. Each category has a different risk profile and should carry a different contingency percentage.

Standard contingency guidelines: 10–15% for cosmetic-only projects, 15–20% for full rehabs including mechanicals, 20–25% when structural work is included, and 25–30% for properties in unknown condition (long vacancy, pre-1960 construction). Contingency belongs as a real line item in your estimate and should be included when calculating your MAO. If your base scope is $70,000 and you apply 20% contingency, your working budget is $84,000 — use $84,000 in the MAO formula.

Labor costs vary the most — typically ±25% from the national average. In low-cost markets like Memphis (18% below) or Atlanta (12% below), the same project costs significantly less than the national average. In high-cost markets like Seattle (22% above) or San Diego (25% above), the same project costs materially more. Certain scope items are also market-specific: foundation repairs in Texas (expansive soils), seismic retrofits in Seattle, wind mitigation in coastal Florida, and pool equipment in Arizona.

Hard money loans are short-term (6–18 months), asset-based loans from private lenders. They close in 5–10 days, are underwritten on the property value (not your income), and fund at 65–75% of ARV. Rates run 10–13% annualized with 1.5–3 origination points. They are designed for acquisition and renovation, with a retail sale or refinance as the exit. Conventional mortgages are generally not available for distressed investment properties. Most fix-and-flip investors use hard money for acquisition, then either sell or refinance into a DSCR loan.

Without an inspection report, estimate from condition observations made during a walkthrough: property age, visible system condition, evidence of deferred maintenance, and observable defects. Build a scope assumption for each trade based on age and condition — a 1975 home with original mechanicals should be assumed to need full HVAC, panel upgrade, and plumbing work until an inspection confirms otherwise. Apply your market's labor multiplier and a 25–30% contingency to account for unknown condition.

Investor-grade kitchen remodels typically cost $18,000–$42,000 nationally. A basic investor kitchen (stock cabinets, laminate counters, standard appliances) runs $18,000–$24,000. A mid-grade kitchen (semi-custom cabinets, quartz counters, stainless appliances) runs $25,000–$36,000. A retail-grade kitchen in a high-end market runs $35,000–$45,000+. Always calibrate finish level to your ARV comp set — the kitchen budget in a $200,000 ARV flip should differ from one in a $450,000 ARV flip.

Scopebase calculates three MAO scenarios from each estimate: Conservative (ARV × 65% − rehab), Standard (ARV × 70% − rehab), and Aggressive (ARV × 75% − rehab). The rehab figure includes contingency. The three scenarios give you a range — the conservative MAO is your walk-away price, the standard MAO is your negotiation anchor, and the aggressive MAO is the ceiling for competitive situations where best-case inputs are achievable.

Yes. While Scopebase is designed for fix-and-flip screening, the repair cost estimates are equally useful for BRRRR investors, landlords evaluating acquisition scope, property managers scoping deferred maintenance, and hard money lenders reviewing draw requests. The line-item output — with cost ranges by trade and risk flags for high-uncertainty items — applies to any situation where you need a defensible pre-construction estimate.
