Before making an offer on a home, determine your budget by assessing mortgage qualification and total ownership costs. Evaluate the home's market value through recent sales and listings. Include conditions like financing, inspection, and condo document review if applicable. Define sale terms such as price, possession date, and included items. Submit the offer with a response deadline, negotiate as needed, and upon acceptance, satisfy conditions before finalizing the sale. Arrange insurance, utilities, and movers before possession day.
