Homeowners have been warned against installing brand new kitchens or bathrooms before putting their home on the market.Michele Lerner of Investopedia.com noted that there are various mistakes that sellers make that can prevent them from shifting a property or that can result in excessive expenses.These include putting in new rooms just before advertising a sale, the writer said, as it was instead suggested that homeowners could opt for cost-effective, minor upgrades like replacing kitchen taps or painting cabinets.Elsewhere, insufficient cleaning was named as one of the reasons for failing to sell a home as dirty properties were described as one of the quickest turn-offs for potential buyers.Not only do they not want to see your childrens art projects (no matter how terrific they are), they dont want to see fingerprints on the walls, dust on the mini-blinds or dishes in the kitchen sink, it was argued.
