https://www.zillow.com/homedetails/1847-Chestnut-Ave-Austin-TX-78702/12345678_zpid/
Pulled the full listing plus 38 gallery photos. Verdict: proceed with conditions — ARV ~$395k–$418k, rehab mid ~$26k. Full write-up, comps, and line-item budget are in your report …
“123 Oak St, Austin TX — worth a look?”
Verdict: Proceed with conditions. As-is vs ARV leaves ~$14k net on a flip after $18k rehab (mid) — thin margin; rental path clears 8% CoC at $1,820/mo rent per comps. Key risk: roof age unknown — flag for inspection.
“FWD: New wholesale deal — 3bd/2ba, asking $185k”
Kitchen: dated cabinets + worn LVP → cosmetic refresh scope. Hall bath: tub surround staining and failing caulk — plan partial gut. No visible foundation cracks in listing set; exterior paint peeling on south elevation.
“What would rehab cost on the Elm St duplex?”
Mid estimate $52,400 (incl. 10% contingency). Kitchen $6,200 · baths $16,800 · LVP + trim $5,100 · exterior paint $3,400 · misc + permits rolled in. High case adds full secondary bath gut.
“Pull comps for 440 River Rd — what's it really worth?”
ARV band $248k–$262k. Best comp: 0.3 mi, 3/2, sold $255k after light cosmetic — +$4k adjustment for smaller lot. Distressed sales excluded; weight on Q2–Q3 closes within 1 mi.
“Seller just dropped price to $160k — re-run the numbers”
Updated at $160k ask: flip net ~$23,800 (was $19,400). MAO vs ask now clears your 15% CoC rule; wholesale fee still leaves $9k+ net to buyer side. Sensitivity: −$5k ARV still passes.

Rehab Estimate
Rehab line items, bid-style.Grounded in the full picture.
Photos first — then Weston stacks context, history, permits, local costs, and market signals so the line items match the property.
Visual scope
Contractor-style walkthrough of listing and user-supplied photos to infer scope, condition, and what still needs work.
Local cost research
Material and labor pricing grounded in the property’s market — not generic national averages.
Satellite & street context
Satellite and street-level imagery to fill gaps — roof lines, lot coverage, setbacks, and exterior context photos can’t always show.
MLS history & listing archives
MLS history, prior listings, and historical photos from our databases to see how the property and its condition have changed over time.
Permit history
Permit records for past work so we know what’s already been improved — and what’s still missing from the budget.
Market & project signals
Nearby projects, market signals, and blended inputs from public government sources plus proprietary databases to stress-test the estimate.
Not a single $/sqft rule — layered evidence. Add photos or details and Weston recalculates instantly.

FAQ
Frequently Asked Questions
Straight answers on how Weston fits into your underwriting workflow.
Weston is a deal evaluation engine for SFR investors. Send us a deal and within seconds we verify the seller’s claims, run the financials, and deliver a structured report telling you whether the numbers hold up — before you spend an hour on it yourself.
However deals come to you — forward a wholesaler email, text or WhatsApp an address or PDF, bulk upload a CSV, or enter directly in the dashboard. You don’t change your workflow, Weston fits into it.
Public records (tax assessments, permit history, flood zones), third-party data providers (comps, rent estimates, market trends), and the deal documents you share. Our analysis is always based on independent data — not the seller’s proforma.
For now, yes. We’re starting with SFR (buy-and-hold and flip) to build the most accurate engine in that market first. We will explore multi-family and commercial based on market feedback and growth trajectory. Join the beta and your feedback directly shapes what we build next.
Your data is stored on Google Cloud and Supabase (US-based, SOC 2 Type II certified), encrypted at rest and in transit, and never shared across clients. Some deal data passes through third-party AI providers under enterprise agreements — never used for model training. Weston’s own SOC 2 audit is planned for H2 2026. MFA is live; SSO and DPAs available on request.
