Urgent Support Needed for Family's Move

I am going to start off by saying, this is very much out of my comfort zone and I really pray I am not met with any judgment.

The home I have created for my children and I for the last 3 1/2 years. The landlord has decided to sell the home right under our feet. The house was put on the market the same day I found out it was on the market, and in less than a week, there was an offer on it. We now have to abruptly move. If you know me, you know asking for help in any way, shape, or form is really something I don't do, but at this point, I really have no choice. I was able to find a new home for us, but with everything moving so fast, I don't have the deposit that I need. So any help is really appreciated. If you would like for me to provide proof of the total amount of the deposit, that is not a problem. Thank you in advance!
