It is considered a righteous act to hold the prayer services in the residence of the deceased.

Below are a several items to consider regarding the Mourner and the prayer service

1. Torah Scroll - A Torah scroll needs to be borrowed for Mondays, Thursdays and Saturdays (mornings or afternoons when the mourners prefer to pray at home) (Notably, it is preferable if the Torah is read three times in Beis ha'Evel (house of mourning) - Aruch ha'Shulchan OC 135:32).
2. Minyan - An adult, male mourner (age 13 and up is counted as part of the minyan, along with nine other males (age 13 and up)
3. Leading the Service - The mourner is able to lead the service
4. No Minyan - In the event that there is no minyan, some say that the mourner should only go to synagogue (Pischei Teshuvah393:2) , if it will not lead to pleasurable activities that would take him out the mindset of "being a mourner."(if the deceased is either a mother or father, the above is true. However, if the deceased is one of the other relatives, then there is a dispute whether a mourner may pray in synagogue during the week) If the mourner anticipates that he/she will not have self control, then he should stay home, even without a minyan.(However, on Shabbat the mourner should go to the Synogague (Rema 393:3)
