Yes I'm sure if you are a mom you understand. Only someone who doesn't have children wouldn't understand. My younger daughter was supposed to move in with him and his girlfriend and all of his girlfriend's family that didn't last not even 3 days she came back to me so now I have to look for a place for her and myself.
Being a mom has nothing to do with it. It was his house. He has a right to sell it and to tell you to either purchase it or vacate it. It is not yours. It is the same with any rental property. If I am renting property and I decide for whatever reason I need or want to sell it then I can. I owe the renter nothing. Unless they have a lease and I would have to wait until the end of the lease. But then I can tell them to get out. I do not have to give any explanation as to why I am selling. This is what happens when you do not own your own property.
I have been responsible since a young age. As soon as I turned 18 I opened a checking account/savings account in my name. I already had a job that I had for quite some time. I applied for my first credit card and started to build credit. I charged and paid in full every month. I rented for a while. I always paid in full and on time. Again, building credit. I had electric and phone in my name. Always paid on time. Again building credit. I bought a new car. I had excellent credit. I paid all payments on time. Same when I wanted to buy a house. I had excellent credit history. The house payment was no more than renting. I live within my means. Nobody handed me anything and I have worked for all that I have.
Also kept excellent records of payments so I did not need to depend on a landlord or someone else to say oh she paid late. I could prove I paid on time.
And btw, I still have excellent credit.
