Our favorite Pacific Northwesterners — real estate agents Lyndsay Lamb and Leslie Davis — are returning to HGTV for Season 4 of Unsellable Houses. The 13-episode season premieres on Sunday September 10 at 9|8c.

During the series, the twin sisters and Washington state natives rely on Lyndsay’s expertise in home renovation, design and staging and Leslie’s budget and negotiation savvy to fight against the slowing housing market and get top dollar for their clients' homes across the Pacific Northwest. Unexpected issues, costly repairs and stressful timelines will stretch them to the limit — but the duo will confidently invest their know-how and even their own money to overhaul stagnant listings and attract the right buyers.

In the first episode of Season 4, Lyndsay and Leslie will help a couple whose spacious yet outdated house in Shoreline, Washington has lagged on the market for more than 30 days. They’ll have to work fast, as the couple already purchased a new home and are paying two mortgages. Through bold exterior finishes and a modern bathroom revamp, Lyndsay and Leslie will transform the house from unsellable to open-house ready.
