10/23/2007 I sold my medical practice for 95k after reducing it from125k and after turning down a cash payment for 105k. The promisary note was to be paid in monthly payments over 24 months begining in Jan 2008 and was interest free. The grace period and interest free was a courtesy as well as the price reduction all to get the note signed. Last month(4 months after the closing/signing) the new owner is telling me he made some decisions to let staff go and make expensive renovations. In the middle of the renovations the city permitting office shut his business down due to lack of proper construction permits. The business has been closed for 9 weeks and many patients have left he is telling me. He is also telling me he can only offer me 25k for the computers,medical equipment and office furnishings that were valued at 43k. He is asking me to accept this as a payment in total and nothing more to follow. He states that otherwise getting the note paid will be "a long haul" for me. Should I sue, negotiated compromise of 65k total? Can I sell the note to a collection company or debt buyers? Thanks.
