Your best bet is to convince her to move.

@Heidi Foster beware betting long with short term money!

A house hacker may be ok with living in an area that is gentrifying or with good fundamentals for upside (you are betting here).

@Peggy Tibbs, you bet. 

Probably your best bet for cash flow here as a few clients of mine own them and do ok, but its a challenge dealing with that type of tenant and might not be the best first investment property idea..

Getting either a real estate broker to comp your house, or better yet, an appraiser to appraise your house are your, two best bets for closer, still not 100% accurate numbers.

So if your partner and you have a deal coming up soon, then your best bet is to start with your own surrounding.

Anyways, your best bet is to find precedent in your target area, or close to it, and see if you can get in contact with them to see what they went through. 

I'd want someone to have my back.Second, if I were to "forget" to mention those kinds of things, my reputation would be in the toilet as fast as you can say "Yelp".I'd bet most good agents would do exactly the same thing.
