Determining the Results of a Simple Experiment. Once the data from the simple experiment has been gathered, researchers then compare the results of the experimental group to those of the control group to determine if the treatment had an effect.
A low appraisal means that the buyer must increase the downpayment amount unless the seller agrees to reduce the purchase price. Both may require an extension of the closing date to allow time to resolve the issue. The buyer must notify the seller of these issues. Any extension must be agreed upon by both parties.
The Seller may request that the closing date be contingent upon the sale of his present home. This date may be rather arbitrary, but a tentative 30, 60 or 90 day closing date could be set and when the actual closing date can be set, then an addendum to your purchase contract can be drawn and signed by both you and the seller.
