Introducing... my immediate sister, Ambition

I want to buy a house, a townhouse Or a condo
but my word IS IT EVER HARD!
i dont know if it'll happen
but i really think its time

i called Ambition to ask if she'd like to buy it together
she mentioned "no, because buying a house and then selling it in less than a year makes you lose money on it" she had a point, but i still didnt get it
she continued "and when you get married, you have to sell it"
by "you", she was refering to herself
so i wonder...
is Ambition getting married soon?
