Do I have to repay homebuyer credit $8000 if I host international student in my home?

Yes, you are committing tax fraud. As soon as you rented it out you needed to send in the check for the 8k. Your apartment does not matter, all that matters is that someone else is living there and you are collecting rent, that violated the terms of the credit.

Of course they will. If any of your tenants file a tax return using your address, they will find out you've used the home as a rental...which automatically makes the tax credit repayable. Plus...there may be other penalties for tax fraud.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
