Review reads PDF, Word and text files, up to 4 at a time. Files are read once to find red flags and are not stored; only the findings are saved in this browser.

Physical diligence

What you've confirmed in person, separate from the paper review.

Documents are sent only when you choose Review, and are not stored. Property details are sent for research and checkout; your deal may be saved locally and with a paid request. Set “print background graphics” on for full color in the PDF.

Underwritten — Deal Memo

Optional professional support

A buyer's agent negotiates on your side — the listing agent works for the seller. We connect you to a local buyer's agent, never the listing agent.

Email (required)

Name (optional)

Phone (optional)

Your details go to one buyer's agent and nowhere else. No promotional email — promised.

Underwritten is a diligence workflow tool, not a licensed real estate, mortgage, insurance, legal, or tax advisor. All outputs are informational estimates from public data and your inputs. Verify all figures with licensed professionals before acting.
