Frequently asked questions

When does my earnest money become non-refundable in a commercial deal?

It depends on the contract. Many commercial purchase agreements keep the deposit refundable during the due-diligence period and make it non-refundable ("hard") afterward, but some make it hard on signing. Find the exact trigger before you wire funds.

Can a seller back out of a signed commercial purchase agreement?

Not freely. Because each property is considered unique, a buyer may be able to sue for specific performance to force the sale — unless the contract limits the buyer to a refund of the deposit. The remedies clause controls, so read it closely.

Should I sign the seller’s standard purchase agreement as-is?

Seller forms are written to favor the seller. Before signing, review the deposit trigger, due-diligence period, financing contingency, title objection-and-cure rights, AS-IS release, and default remedies — either the buyer or the seller can request redlines.
