The problem

Underwriting shouldn't take an afternoon.

Most investors run deals through a spreadsheet they half-trust, then make a six-figure decision on a gut feel. Pencilwrite replaces the whole ritual.

01

Spreadsheets break silently

One dragged formula and your cap rate is off by 2 points — and nothing tells you. Stale tabs, copied errors, no audit trail.

02

Comparing deals is manual

Five tabs, five layouts, five definitions of "ROI." Lining up a rental against a flip means rebuilding the math every time.

03

You guess at the offer

You know the return you want, but not the price that hits it. So you anchor high, lowball, or walk from a deal that actually worked.

The Pencilwrite difference

Inputs to a decision in four moves.

01 — Instant metrics

Every number that matters, the moment you type.

Cap rate, cash-on-cash, DSCR, GRM, the 1% test — and a true ROE that counts cash flow, principal paydown, and appreciation together. Not a guess. The whole picture.

  • 30-year projection with live commercial rates (Treasury + spread)
  • HUD fair-market rents and curated appreciation baked in
Cap rate7.9%
Cash-on-cash9.4%
DSCR1.42
GRM7.4
True ROE · yr 118.6%
02 — Offer Optimizer

Back-solve the highest price that still works.

Set the return you need — a target cap, cash-on-cash, DSCR, or monthly cash flow — and Pencilwrite solves for the maximum price that hits it. Walk into the negotiation knowing your ceiling.

  • 70% flip MAO and creative-finance scenarios included
  • Every offer ties back to a number, not a feeling
TARGET · CASH-ON-CASH ≥ 9.0%
Max offer$531,400
03 — Tax & REPS modeling

See the deal after taxes, not before.

Depreciation, cost-segregation bonus, REPS vs. passive treatment, after-tax cash-on-cash, and a 1031-deferral estimate — the lens that actually changes which deals you take.

  • Real Estate Professional status modeled, not hand-waved
  • After-tax return sits right beside the headline number
Pre-tax CoC9.4%
After-tax CoC · REPS13.1%
04 — LOI & offer sheets

From "this works" to a sent offer in one click.

Generate a letter of intent — cash, seller-finance, or creative — plus a clean one-page offer sheet, ready to print or PDF. The deal goes out while it's still hot.

  • Save, load, and compare every active deal side by side
  • Pipeline from analyzing → offered → under contract → closed
