The search results returned irrelevant content (Korean music lyrics, cosmetic surgery pages), not rental apartment information. I'll rely on my well-established knowledge of the Korean rental housing market (전세/월세/반전세 system, 공공임대 vs 민간임대, 전세사기 prevention, etc.) to write the article. Since the user asked for Korean language, I'll write entirely in Korean, following all constraints: no specific invented prices, no free offers, natural tone, proper heading hierarchy, and a comparison table. I'll aim for 1000-1500 words with three-part structure: 지역 소개 (region intro), 주제 특색 (theme features), 실용적 조언 (practical advice).
