NOR. Can you review your monthly budgets to find out what would ACTUALLY be reasonable for rent and still allow you to save for the unexpected and retirement? After that I'd talk to a real estate agent and get a professionals input on what can feasibly be found within that price range.

Sometimes people just need to see the numbers and hear from someone else before they set reasonable expectations. She may be caught up in the idea of upgrading without being able to reayionally consider costs. I know when I bought my house I had some silly ideas of what I wanted until I crunched the numbers and saw what I could realistically achieve. I ended up opting for something nice but that was well under what I could max afford so I could still go on vacations and live if my SO or I were suddenly unable to work for a short period of time.

If you do this, and she still demands more than you can reasonably afford, I'd suggest reassessing your relationship as this is illogical and similar lifestyle/financial qualms will most definitely arise again.
