Selling Property with Tenants in Situ

Selling off properties with tenants in situ and wanting advice on selling without using estate agent.

Is anyone looking for an investment property or does anyone know somewhere I can find active investors - only other investor I know actively buying has bought one, but want to sell the rest too without extra fees.

Thanks for any help

Auction might be best bet

What areas are the properties?

All are in Scotland, mostly in and around Glasgow/Lanarkshire with a few further afield.
