Can anyone advise me the best up to date tenancy contract to use.
Should I do one on my own accord, or is there any companies that provide guaranteed contracts.
I was going to pay £49 to Open Rent to do this, but its not available in Scotland
Take a look at the Scottish Association of Landlords. The associations usually have a wide range of model documents that are frequently updated.
You need a TA specific to Scottish housing law.
Tessa Shepperson has them on Landlord Law I think
NRLA may have them
