A finance condition, in plain language
A finance condition is a clause in an agreement that leaves room to sort the loan before the purchase becomes binding. Your agreement is the version that matters. This page only describes the idea.
What a finance condition usually is
When an offer is conditional on finance, you are asking to buy the home only if the lending can be arranged on the terms the agreement describes. The date and the wording come from that agreement. Your lawyer reads them. This site does not set those dates, and it does not tell you to waive the condition.
How it sits next to pre-approval
Pre-approval, when a lender offers it, is a view of what they might lend based on what you have told them so far. It does not, on its own, satisfy a finance condition. The lender still looks at the property. A valuation and final checks can still sit in front of you. It usually lasts 90 days, but it pays to check with your lender.
Why an unconditional offer is a different risk
An unconditional offer leaves less room if the loan, a report, or the property later turns out differently from what you expected. Stepping back after the conditions are gone is much harder. The buying process page is the short outline of that path. This page is not a reason to make the offer unconditional.
Auctions and tenders are not the same path
Auction and tender sales often work on a tighter set of rules, and you may have to be ready before you bid or submit. That is a different shape from a private offer with a finance condition and a date. Your lawyer can say which one you are looking at. This site does not recommend a sale method.
A soft next step
If you want a broker to look at your plans before an offer, use get started. That is a match, not advice about the clause in your agreement.
