I am renting a one-bedroom apartment in a rent pressure zone to a tenant the last five years. Rent is low (relative to other similar properties nearby) and I cannot raise it due to being in a rent pressure zone. My tenant has qualified for a HAP scheme and asked me to sign the necessary documents. Will this hinder me from raising rent in the future should the political landscape change? Are there downsides to this that I should be cautious about? Thanks in advance.
