My friend bought a house, paid a down payment, and now he pays it back every month, but he can't afford the latter. He wants to transfer it to me. Is it feasible?

Pay off the loan first. If it's not up yet, ask the guarantee company to help you pay back "that will cost money". After paying off, you can get the real estate license and handle the transfer. If you also want a loan, you can apply for a mortgage with the real estate sales contract when you return the real estate license. You have to pay taxes when you transfer the ownership. If his house has been bought for less than five years, you have to pay 5% more business tax.
