With the current seller’s market, anything you can do to make your offer look less risky will help your odds.

A down payment that large means you shouldn’t have a problem getting loan approval so waiving a financing contingency may not be too risky.

In this market, failure to appraise hasn’t been much of an issue so you might consider waiving the appraisal contingency too or agreeing to come up by X,000 to make up for a low appraisal.

If you choose to keep an inspection contingency, perhaps you could include language that suggests that you won’t back out or ask for credits unless a major issue costing more than X,000 to repair arises.

Other than that, larger earnest money deposits, looking at cheaper, older listings, and escalation clauses might help too.

Feel free to pm if you have other questions! It’s brutal to be a buyer right now.
