Answer

You can left join twice and ensure that one of the joins succeded. The rest is aggregation:

select 
    p.name, 
    string_agg(distinct h.city,  ' ' order by h.city) cities,
    string_agg(distinct c.brand, ' ' order by c.brand) brands
from person p
left join house h on h.person = p.id
left join car c on c.person = p.id
where c.person is not null or h.person is not null
group by p.id, p.name

Demo on DB Fiddle:

name   | cities          | brands      
:----- | :-------------- | :-----------
Mark   | Chicago Moscow  | null        
David  | Boston New York | toyota volvo
Andrew | null            | bmw opel
