Hello~ Can you help me say this naturally please?

A: I have run through so many share-houses and I most like your house.

B: Oh, thanks, so you want to rent it? Itís $180 a week.

A: Huh? Didnít you say itís $118? Oh, dear,, I think I misheard it.
Sorry, I canít take it then.
ⓐBecause itís over my budget.
ⓑBecause itís out of my budget.

B: whatís the maximum rent you can afford?

A: Itís embarrassing to say that but canít over $130.

B: Sorry, there is too much gap, if itís $160 I can provide you.
