I have my first house hack under contract! Questions

[John Daniel]

Hi there! Very exciting news, over the weekend I was able to get the home I wanted under contract, it is a 4 bedroom 3 full bathroom home in a fantastic area. My goal is to house hack it. I have some questions that have been brewing in my mind. 

1) I'm a first-time home buyer is there any programs I can take advantage of? I've talked to my lenders and am being told with covid many of those have gone away. 

2) Can I/should I quickly open up a first-time homebuyers savings account? From what I read there are some tax benefits when it comes to doing this. The property is in Missouri.

3) Should I open up a new checking and savings account for this property? 

4) Any other benefits I should plan on taking advantage of as first-time homebuyer? Or things I should know?

Thanks in advance!
