After four years, the lady I sold my townhouse to (who lives out of state) hasn't made a payment to me in three months. I tried to contact her by mail as the telephone number is unknown, to ask her her intentions on this property. Still no reply. What do I need to do next? Hire a lawyer (which I in no way can afford right now) or what can I do? Can I do it without a lawyer? Please help me, I am completely unknowledgable about this subject. Thank you so much.
