Freehold with RTB s156A and housing association consent restrictions

Hi all, FTB here, buying a freehold ex-housing association property that was originally sold under Right to Buy.

The title has both an s156A/right-of-first-refusal restriction and a separate restriction saying the property can’t be transferred without the housing association’s written consent. Both expire in 2029. My solicitor is checking whether my mortgage lender is happy with this but it's taking ages...

Has anyone had a mortgage approved on a property with these kinds of restrictions? I’m trying to work out whether this is routine paperwork or something banks can get fussy about.
