Renovation loan is available up to S$30,000 or six times monthly household income, whichever is lower, for Singapore Citizen resale buyers over up to five years.
practical tips for the common bedroom
- Do not hack structural walls, beams, columns, or the original reinforced concrete floor screed, as these are banned.
