The DealDoctor Report

The full underwriting package.

Everything a serious investor checks before writing an offer — delivered as one shareable link, documented line by line.

I.Underwriting math

Every figure is deterministic given its inputs. No magic; each line of the math is documented in the methodology.

Exact Breakeven Offer Price

Binary-searches the purchase price at which Year-1 cash flow crosses zero given today's rent estimate and the investor-adjusted mortgage rate. Your literal walk-away number.

Total Cash to Close

Down payment, ~2.5% closing, inspection, appraisal, 6-month PITI reserves, rehab. The real "how much do I need?" figure.

5-Year Wealth Projection with IRR

Cumulative cash flow plus principal paydown, appreciation, and depreciation tax shield. Year-5 sale assumes 6% selling costs.

Financing Alternatives

FHA · Conventional Investor · DSCR. Side-by-side: down, rate, DSCR, cash-to-close. The adjustment other tools silently skip.

Sensitivity Stress Test

Rent ±10%, rate +100 bps, expenses +20%, appreciation 0–5%. A tornado chart ranks which risk carries the most downside.

II.Data anchors

Real market signal behind every computation — so you can verify, not just trust.

Address-Adjacent Sale Comps

Rentcast sold records within a 1-mile radius, with $/sqft and days-on-market.

Rent Comparables

Nearby rentals the rent estimate was priced against — the number that drives everything else.

Zip-Level Market Growth

12-month price and rent trends piped into the 5-year projection. No flat 3% guess.

Climate & Insurance

FEMA flood zone + NAIC state baseline + hazard scores flow into the monthly expense stack.

Location Quality

Walkability, amenity counts (groceries, transit, schools, parks) within ~½ mile via Mapbox Tilequery.

III.AI diagnosis

A property-specific read from a reasoning model — not a template.

Deal Doctor Diagnosis

Pros, cons, three negotiation scripts with specific dollar amounts, and two property-specific inspection red flags tied to year built and climate. Powered by Anthropic.

Photo Red-Flag Review

Drop listing photos; the vision model flags observable condition concerns — roof, water damage, visible structural — with severity.

IV.Professional polish

The details a lender or partner will look for.

Interactive Rehab Estimator

Enter rehab cost + expected rent bump; every metric (cash flow, DSCR, wealth, IRR) recomputes live.

STR vs LTR Comparison

Full Airbnb/VRBO P&L with 43% variable opex + STR-specific insurance. A verdict chip calls the winner by $/mo.

State Property-Tax Modeling

CA Prop 13 2%/yr cap, FL Save-Our-Homes 3%, TX uncapped. Per-state reality instead of a flat growth rate.

Investor-Rate Premium Applied

+75 bps over Freddie Mac PMMS for DSCR and non-owner-occupied loans. Flips DEAL vs PASS on marginal deals.

What readers ask.

The math is exact; the inputs are estimates. AVMs (property value, rent) carry ±10–15% error bars by design. Mortgage math, DSCR, depreciation, and breakeven are deterministic given those inputs. Every data source is cited in the report footer and on the Methodology page — no magic.
