Renting a room in your house
Yes, we know that this idea could sound really bad, but you can give it a try, though. So, this is the moment when you can test your skills as a psychologist and look carefully for an honest and loyal person who wants to rent a room in your home.
Maybe a student or someone from another city who needs a home but pays for it would accept your offer. It is true the fact that not everyone is ill-intentioned, so if you can find someone worthy of your home, then you can even earn a lot of money monthly.
