Good people who have very few housing options are *very* likely to stay, pay rent, and cause no problems. 

The new single family home construction will likely cause some appreciation in the value of the duplex, but the housing type is different, so it might not be a whole lot.

Obviously, these are long-term improvements on the property, but they were caused by a vacancy.

Electrical and plumbing make up for the biggest headaches and cause a lot of problems.

I expect inflation to continue, causing rent prices to increase, and housing to become even more unaffordable. 

Sometimes it’s difficult to get hold of them for days or even weeks, meanwhile the problem gets worse or you have to take matters into your own hands.The other problem with condos is WHEN the neighbors cause problems you’ll have your tenant whining about the noise, smoke seeping through their unit, etc.

If not, is there anything that i can do to discourage her from continuing to cause drama/problems with the other tenants?

Not to mention the civil unrest causes another bout of mass rioting in the streets of major cities that your investment happens to be in and then that area never recovers. 

Nothing gets installed on top of the planking cause they need to expand and retract with temperature changes, plus you need at least 1/4" space between the flooring  plank and baseboards or walls to allow for movement

Also, buyer's were informed by their lender that their loan is about to expire so they would have to be approved once again.Buyer has 3 little girls all in grade school so you can imagine the stress and inconvenience this has caused them.
