I know someone who had terrible experience with marriage.

But again, its like getting into marriage, make sure you test the waters first, don't go to the alter day one.

A few years later, we re-purposed a large walk-in closet to a master bathroom and went a little crazy (close to$14k), but adding a 3rd bathroom (and making a house w/out a master complete with one) paid dividends in value (and my marriage:) We went into purposely and for the "value add" component.Finance:  At the time my wife and I were only approved for a fraction of what we could afford due to renting out our home (with a large mortgage).  

Property value tripled, my life situation changed (marriage/kids/etc).

Getting hustled like this is actually strengthening my marriage.  

If she makes these kinds of choices when you are married (assuming you are headed for marriage), it could ruin your marriage. 

I am a navy veteran and on my second marriage so I am a proponent of second chances. 

 Couple of thoughts:Profit from selling one of the two condos won’t be cap gains, it will be ordinary income and not eligible for a 1031.A two unit “condo association” will turn off many buyers.....no professional management and it turns out like a “marriage” with the adjoining unit owner, potential for a lot of disagreement.

Because there are plenty of people that aren't related by blood or marriage, etc. living together, and thus related by relationships. 

She started to cry and plead with us that she's had her heart set on getting a puppy and has given it much thought, is going through an emotional time right now, would gladly pay extra rent or extra security deposit, would keep the dog in the garage and yard only if we wouldn't allow it in the house, is distraught because she and her husband (married just last May) decided not to expand their family at this time (she has a young daughter from a previous marriage), this was a disappointment and she needs the puppy for emotional support.
