Collection Agencies Government Debt

I have an old issue of lease agreement with HUD, Section 8 housing.
I owe them $ 2,600. I just received a letter from a private company wishing to $ 3,201.19. Apparently, some collection agency has bought my debt.
Then these opportunistic portfolio rapers take my money control, credit card / debit card, savings or wages?
I have a small check / ATM account to pay bills, buy food and cash checks workday.
And to save money for my current monthly rent. I still live in the same place, but were the start of the section 8 program, which is why I owe them this money for two years.

So ... Can a non-governmental private company to enter my property?

No, only the IRS can do. Get a lawyer.

No, they can seize your property, but they obviously adversely affecting your credit you will pay more interest on loans or credit cards as you exit. Later, if you buy your own home, then they can put a lien on the subject.

they could be if they obtained a decree against you by a court

No NGO can seize your property without a court order. For them to get a court order, it must first be a hearing and you have to be notified of this hearing so that you can defend yourself. Creditors harass you and make every effort to get money from you, including lying to you. If the debt is legitimate, make arrangements to repay a way that is comfortable for you, but do not live everyday in fear.
