Changing closing date

[Susan Franco]

Hello,

  I'm new to RE investing, and this is only my third deal. I had a contract to sell a house for 225K with 1000 in escrow on 1/7 , inspections and appraisals are all done, closing was to be 2/21, and they called yesterday wanting to push it to march. I stupidly did not have a must close by date on my contract, they have offered to give  me more escrow to extend the closing, and I have this opportunity to have the contract amended I believe, and add it must close by _____, and demand more escrow, to protect myself. I don't want to involve an attorney, and they are willing to work with me, but I don't want to do anything improper.
