As a former landlord i’d Do the barest minimum beyond legal requirements in an unfurnished property.
You sort the basic fabric, smoke & CO alarms, gas safety certificates, the kitchen & cooker. Let the tenants sort out white goods, furniture, tv etc. The more money they ‘need’ to put in, the less likely they are to trash the place.
ABSOF***NGLUTELY NO DOGS. NO SMOKING.
dishwasher a bonus. Cable/satellite tv connection, broadband essential for high end / “professional” tenants
