The Houses Usually Preferred for Rahu and for Ketu
A workable Rahu is usually sought in the 3rd, 6th, or 11th. A workable Ketu is usually sought in the 12th. Those preferences are about matching the node's habit to the house: Rahu inflates effort and gains, Ketu releases. The sign lord can veto either preference.
Rahu's three working rooms
The 3rd lets Rahu inflate courage and craft. The 11th lets it inflate income and networks, which is why that house is separately called the favorite. The 6th lets it inflate the fight against rivals, with the dusthana cost of debt and illness still attached. The 10th is an upachaya too, and it is left off some 'good' lists because a career Rahu is public and unstable even when it succeeds. The 1st, 4th, 7th, 8th, and sometimes the 5th and 9th are where teachers hesitate, because the amplifier sits on the self, the home, the spouse, the crisis, the children, or the guru. Hesitation is not a curse. A strong Jupiter dispositing Rahu in the 9th can be an unusual teacher. The list is a default, not a fence.
Ketu prefers the house that already lets go
The 12th is loss, foreign residence, sleep, and moksha language. Ketu's detachment fits. Ketu in the 6th can also work, because the 6th is an upachaya of enemies and service, and a dry fighter is sometimes useful. Ketu in the 3rd specializes a skill. Ketu in the 1st, 4th, or 7th detaches personality, home, or marriage, which is a harder fit for ordinary life and a possible fit for a person who wants exactly that spareness. Rahu will always sit opposite. A 'good' Ketu in the 12th means Rahu in the 6th, which is on Rahu's preferred list. A Ketu in the 6th means Rahu in the 12th, which is not. You cannot optimize both ends of one axis. Choose which node's house you are willing to call good, and accept the other.
Dignity and dasha outrank the default
Ketu in the 12th in a fallen dispositor's sign is a release into a weak vehicle. Rahu in the 11th disposited by an exalted graha is the preference actually earned. Rahu's 18 years and Ketu's 7 years are when the preferred house either pays or shows its cost. Outside those periods the natal note is quiet. Do not wear hessonite or cat's eye because the node occupies a 'good' house. Confirm the sign lord's other houses from the lagna. A good room with a dusthana landlord is a mixed tenancy.
Frequently asked questions
Why is the 10th left off some Rahu lists?
It is an upachaya, so effort grows there, and it is also the most public kendra. Success tends to be visible and contested. Lists that want a quiet gain prefer the 11th.
Can Ketu in the 12th and Rahu in the 6th both be the preferred pair?
Yes. That is one axis: Ketu releasing in the 12th, Rahu working in the 6th. The reverse axis puts Rahu in the 12th, which drops off Rahu's short list.
Does the preference survive a weak dispositor?
Barely. The house match is the default. The sign lord is the veto. Say both before you call the placement good.
