Joseph, Rambam said that about a person who has a trade. I imagine that that would also go for people who can set themselves up for a long time with one or two deals (e.g. chazanim who make enough during the Yamim Noraim to learn the rest of the year or diamond merchants). He himself had a grueling work schedule as he wrote to his translator Samuel ibn Tibbon.
Avram, Judge Learned Hand (yes, that was his name) said “Anyone may arrange his affairs so that his taxes shall be as low as
possible; he is not bound to choose that pattern which best pays the
treasury. There is not even a patriotic duty to increase one’s taxes.
Over and over again the Courts have said that there is nothing sinister
in so arranging affairs as to keep taxes as low as possible. Everyone
does it, rich and poor alike and all do right, for nobody owes any
public duty to pay more than the law demands.” The same should go for benefiting from Section 8. However, IMHO it does not “smell right” to deliberately have a low income in order to qualify. It should not matter who owns the house. Chazal (Avot D’Rabbi Natan 11:1) believed that “A person should love work and not hate it; for just as the Torah was given with a covenant, so too was work given with a covenant.”
