Making the homes as competitive as possible, i.e. doing the fixing up that is required is a very big plus when it comes to impressing the buyers of today's market.
1. If your home is in a neighborhood that is known for rental units you probably do not have to fix anything up to sale the home.
2. If your home is in a neighborhood where the majority is owner occupy, you will need to fix the home up as the new owners will desire a turn key property.
