I'm probably over thinking but I feel a bit suspicious.
Council exchange/swap
Property 1:
Old build 1930s . 3rd floor no lift . No garden. Good storage. Bedroom one is very big. 2nd bedroom is a single room with build in cupboard. Can fit basic furniture. Large living room . Small basic kitchen. Separate toilet and bathroom. Small brick balcony.
Property 2:
New build . Ground floor. Gated communal garden. Bedroom 1 king-size. Bedroom 2 small double. Big fitted kitchen. Large balcony. Good storage. Wet room.
Why would Property 1 want to swap with property 2? The properties are about 15 mins from each other.
