Just checkatrade part. But there is nothing else, just his van and tools. He's retiring Dec this year.
I don't think I need accounts or anything, I've rented his mobile off him previously for months at a time and so all I'd need to do is have a trial period of a month or a few months to check calls still come in like before. It's just a checkatrade page which advertises the same stuff I do and has lots of feedback referring to the same stuff I do. Which is small maintenance. So it's a high lead generation, small job type affair.
I have no savings to my name unfortunately otherwise I'd probaby attempt a negotiation based on an upfront figure.
So if you are taking the phone number from him and the checkatrade account is the only way he advertises then anyone who has his number will now be calling you. So surely seeing his accounts will show you how profitable his business has been over, say the last 3 years, and only then can you look at putting a value on it. If hes been making 10k per year then you will want to be paying less than if hes been making 50k per year.
