Specialty · Pre-Purchase Technical Review

Decide if the site works before earnest goes hard.

Most preventable losses on a real estate deal are decided at closing — when a constraint that an engineer could have flagged in a few hours becomes a six-figure entitlement problem post-acquisition. Avidan surfaces those constraints before the deposit goes non-refundable.

When to engage

Before the deposit goes non-refundable.

The best time for due diligence is the moment a site looks interesting and before any non-refundable money is on the table.

Pre-LOI

Quick desktop screen before submitting an offer. Surfaces deal-breakers in 24-48 hours so the LOI either goes out clean or doesn't get sent.

Inside the diligence window

Full technical workup during the contractual due-diligence period. Outcome supports a price renegotiation, contingency removal, or termination.

Pre-closing extension

Already past initial diligence and need a second look before extending? We pressure-test what the seller's package said and what your team has confirmed.
