Buyers’ Representation

Simonson Real Estate & Auction Service represents buyers throughout Wisconsin. We strive to make the house search much easier and more efficient than if you were to go at it alone. Our highly-qualified realtors can introduce you to a great lender, guide you to local neighborhoods, help you determine your budget and prioritize your wish-list for your next home. By only showing you properties that meet your requirements and budget, we’ll save you valuable time.

Once you’ve found the home of your dreams, we’ll research comparable properties in the area to determine a fair purchase price and draft a formal “Offer to Purchase.” We’ll then negotiate on your behalf to ensure you receive the most favorable terms. We’ll be by your side every step of the way, from the first showing to the closing table.

Sellers’ Representation

Selling a home or property on your own can be a daunting and stressful task. Make the process easy by choosing to work with Simonson Real Estate & Auction Service. We’re here to help you plan and prepare your home for showings, negotiate offers, work out contract contingencies, and coordinate with the title company to prepare the documents for closing.

First, we’ll perform a comparable market analysis to determine the best price for your home. We then offer staging advice and suggest repairs or maintenance that will enhance your home’s appearance and attract more buyers. We’ll advertise your home through a number of channels and even include it in our featured listing.

When it’s time to negotiate an offer, we’ll ensure you receive the best price the market will allow. Ultimately, our team is here to help you throughout the entire selling process and complete a successful real estate transaction.

Diane and the Simonson Real Estate team have been amazing since the first time we used them over 15 years ago. From the sale of our first hours to the purchase of our second house, as well as the sale of our second house, Diane has been straightforward with us and has always had our best interest in mind. She knows us, knows what we look for in a home, and keeps us up to date with the listings. Thanks so much Diane!!
