Search Results: how do I get my family back

If a random guy you have never met before does an act of kindness for you like the scenario bellow how do you think you would repay them?

It's late you have had a pretty rough night out your still fairly sober but overall it was a mess. You come back to your townhouse and up the stairs you fumble to find your keys upset and just wanting to get inside and forget about it all.
However you find your keys but they slip from your hand and fall down the steps upon trying to go back down to retrieve them you slip and fall landing on your side at the bottom. You have a twisted leg and potential broken arm, in massive pain no one in site. It's a winters night and like most women follishly wore short dress and heels however you do have a jacket on at least. It's partially snowing and icey too.
A minute passes and a guy spots you runs over to check on you and notices what has happend. He calls for an ambulance and stays with you comforting you offering kind words untill the ambulance gets there. He acompanies you to the hospital after asking if you would like that. Your family lives away from you in another town. You are also single too so don't have anyone really close apart from some friends etc.

After you have been treated I go and check on you and tell you I have to go as I have plans tommorow and need to get some sleep.

I'm going to keep it as short, brief, straight to the point as best I can.

Parents divorced, mother owns 100% of the house as she bought it from my father.

My older brother paid off his house (My parents gave him 50% down payment during the 2008 recession so houses were cheap...)

Brother has two kids, part ownership of the family business in a different city than me. (He works there)

My mother owns 40% shares of the business.

She's getting older and her health is declining.

She's worried that I won't have a house of my own. (Just a mom being a mom) She came up with an idea and has been asking me at least once a month about this..

She wants me to pay x amount for her house which is a great deal.. she'd sell me her house for 1/5th the market price. Her thoughts are that this house would be mine and my brother can use the money plus she'll be giving him more money on top to buy another house so my nephew and niece can have one each.. She thinks that's fair because if she passes away my brother has the rights to own 50% of this house.

Okay... with that being said... I think it's a great deal... it's the house I grew up in. Now for the part which makes me think twice... She keeps telling me its fair to do so when they already gave my brother a 50% down payment which back then is the equivalent to how much I'd be buying the house for.. Soo how is it fair if my brother will now practically be given 50% down payment along with in this current housing market where he lives another 75% down payment. She's also giving 100% of her 40% shares of the company to my brother, I get none of that. She said, "he works there and you don't". Well I used to live in the house, live in the same city of the house and do all the maintenance for it including expenses out of my pocket..

I'm torn between saying fk it.. split the house and I'll sell it when you're gone and buying it out then renting it out.

What would you do?
