it means they will accept a land contract for the sale. It means that an offer has been accepted. You can still make a secondary offer on the home but it will not be presented to the seller until and unless the first contract falls through, at least in the US.
A premature birth is a birth that takes place more than three weeks before the baby is due. In other words, a premature birth is one that occurs before the start of the 37th week of pregnancy. Normally, a pregnancy usually lasts about 40 weeks. Premature birth gives the baby less time to develop in the womb. Premature babies, especially those born earliest, often have complicated medical problems.
Those final weeks in the womb are crucial for healthy weight gain and for the full development of various vital organs, including the brain and lungs. This is why premature babies may have more medical problems and may require a longer hospital stay. They may also have long-term health issues, such as learning disabilities or physical disabilities. In the past, premature birth was the major cause of infant death in the United States. Today, the quality of care for newborns has improved, as have the survival rates of premature babies. Yet premature birth is still the top cause of infant death worldwide, according to the Centers for Disease Control and Prevention.
