However, this does not release her from the mortgage responsibility unless the loan is paid off or refinanced.3.

If you wait 2 more years there and it appreciates more, you may have enough to sell it, get the bigger house, and have some leftover to invest into a purposeful investment.

Purposely letting her dog run around and using others laundry, demanding the other tenants do things for her.

Appreciated reading every response on this post. 

@Jaron WallingThank you for the response and insight.

We also have a stern conversation with them about not hiring vendors and that they would be fully responsible next time.

While you can't create limitations against their lease and legal rights they have for quiet enjoyment, things like keeping common areas free of clutter or routine maintenance items that are tenant responsibility can often be added to help keep the expectations on both parties clear.

Spell out the complete agreement of how expenses, profits (or losses), and other responsibilities are to be split—put everything in writing.Do a background check on the partner to confirm there are no outstanding liens, judgments, or active lawsuits against them.Hope these suggestions help.

Thank you so much for the response!!

Hi, this is a high rise condo and the building is responsible for the ventilation system which is not working, not only in my unit (bathroom & kitchen) but in the entire building.
