The repair estimate is the most important number in a wholesale deal. Get it too high and your offer is uncompetitive. Get it too low and you either lose your buyer's trust or the deal falls apart when they walk the property. Getting it right remotely is possible, but only if you have the right inputs. For a full walkthrough of the underwriting process, see the wholesaler's guide to remote property underwriting.
This is the system virtual wholesalers use to scope repairs without ever leaving their desk.
Step 1: Get a Complete Photo Set First
You cannot estimate repairs from incomplete photos. If the seller sends you six pictures of the living room and a blurry exterior shot, your repair estimate is going to be a range so wide it is useless. The first step is not math. It is getting complete, high-quality photos of every major system and room in the house.
A complete photo set for repair scoping should include:
- Roof: exterior from multiple angles, any visible damage
- HVAC: unit with data plate visible to determine age
- Electrical panel: open panel showing breakers and wiring
- Water heater: unit showing age and condition
- Basement: all walls, floor, and any signs of water intrusion
- Kitchen: cabinets, counters, appliances, ceiling
- All bathrooms: tub/shower, vanity, floor, ceiling
- All other rooms: floors, walls, windows, ceilings
Use a guided submission tool. Asking sellers to text you photos rarely produces a complete set. A tool like SellerSubmit walks the seller through the property room by room, validates every photo before they can move on, and sends you everything organized in a dashboard. That is the foundation for a reliable remote estimate.
Step 2: Categorize the Work
Split the repair scope into two categories: systems and cosmetics. This matters because the two have very different cost profiles and risk levels.
Systems (High-Cost, High-Variance)
Roof, HVAC, electrical, plumbing, and foundation are the items that can double a repair budget. A property with a 5-year-old roof and updated HVAC is a fundamentally different deal than one with a 25-year-old roof and failing mechanicals. Photos help you assess these before committing to a number.
- Roof replacement: $8,000 to $18,000 depending on size and material
- HVAC replacement: $4,000 to $10,000 for a full system
- Electrical panel upgrade: $2,000 to $5,000
- Full plumbing update: $5,000 to $15,000+ depending on scope
- Foundation repair: $3,000 to $20,000+ depending on severity
Cosmetics (Predictable, Per-Square-Foot)
Paint, flooring, kitchen and bath updates, fixtures, doors, and trim are the predictable items. Once you know the scope (full update vs. light refresh), you can estimate these reliably by square footage.
Step 3: Use Cost-Per-Square-Foot Benchmarks
Once you have categorized the work, apply these general benchmarks. Adjust up or down for your specific market and labor costs.
| Scope Level | What It Includes | Estimated Cost/sqft |
|---|---|---|
| Light cosmetic | Paint, carpet, minor fixtures, cleaning | $10 to $20/sqft |
| Full cosmetic | Flooring, full paint, kitchen refresh, bath updates | $20 to $35/sqft |
| Full rehab (no systems) | Full cosmetic plus windows, doors, landscaping | $35 to $50/sqft |
| Full rehab with systems | Everything above plus roof, HVAC, electrical, plumbing | $50 to $80+/sqft |
Apply the appropriate range to the property's square footage, then add your itemized system costs on top.
Example: 1,400 sqft house, full cosmetic rehab needed, roof is old and HVAC needs replacement. Full cosmetic at $28/sqft = $39,200. Roof = $12,000. HVAC = $7,000. Total estimate: $58,200. With a 15% buffer: $67,000 in your underwrite.
Step 4: Add a Remote Buffer
Because you have not physically walked the property, add 15 to 20% to your estimate. This covers deferred maintenance hidden in walls, scope creep once the rehab starts, and permit costs that vary by municipality. If the deal works at your buffered number, it works. If it only works at the unbuffered number, you are taking on risk you cannot see.
Step 5: Validate with a Local Contractor or Inspector
For larger deals or deals with significant system questions, get a local contractor or inspector to do a walk before you lock in your final offer. Even a $150 inspection fee is cheap insurance on a deal with a $30,000 repair question mark. You can make your offer conditional on inspection to keep the option open.
What to Do When Photos Are Not Enough
Sometimes photos reveal a red flag but do not give you enough to scope the damage. Visible foundation cracks, ceiling staining suggesting a major past leak, or visible mold all warrant either a targeted follow-up photo request or a physical inspection before you commit to a number. Do not just add a bigger buffer and hope for the best. Get the data you need to build a complete condition report and underwrite confidently.
