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.
The record for the smallest premature baby to survive was held for a considerable amount of time by Madeline Mann, who was born at 26 weeks weighing 9.9 oz (280 g) and 9.5 inches (24.1 cm) long. This record was broken in September 2004 by Rumaisa Rahman, who was born in the same hospital at 25 weeks gestation.
