Yes, they had all of the qualifications, but they were very loud talkers and I was worried they would disturb the other tenants.  

If the tenant for the house had kids, they may disturb the apartment tenant a bit since the apartment shares a bedroom wall with one of the upstairs rooms.I guess it's one of those things I can try out and see.

We do this so that we are not disturbing our current tenants with multiple showings at random times.

Your turnover unit will tell you what's market and then adjust for condition of the not updated unit.Painting inconveniences the tenant but some improvements you can do without disturbing the tenant too much include updating a fridge, toilet or vanity.

@Jessica SorensenThere is usually a portion in the lease that has to do with not disturbing neighbors, being too loud, too late and etc, etc.  

Some are wonderful tenants that pay their tenant portion on time, keep their units clean, do not disturb others and are just nice people who for whatever reason need help.On the other hand, we just had one section 8 tenant who moved in at the end of November, never made even one tenant portion payment and it took us ~4 months (end of March) to get rid of him.

I hope so, and that you have written your partnership up so that you are not liable for whatever he does as a tenant.If you have a lease with your partner, I would bet that there is a provision in your lease that says tenants must not violate any laws or cause disturbances, etc.  

Also if it's a first time ofense you should send a disturbance notice.

In that letter,  list the dates and times of problem behavior and in the letter state that these tenants are disturbing you and your wife's right to "quiet enjoyment" of your property.  

Let them know the sooner you show it the sooner they will not be disturbed again.
