That advert is a come on. £1500 a month but its work for two men?

Difficult houses by the sound of it. There are a lot of difficult Victorian town houses in Harrogate. He goes on about all the potential and yet he hasn't developed the potential and sold the round for more.
You can't sell a round and say is got potential. Potential for what? Knocking on doors and getting more work YOURSELF! Why pay someone 10X for the privilige of canvassing up your own work??
Far too much marketing speak in that advert. My guess is that if you checked up that round will only have been canvassed up in the past few months although it says established 1 thats probably bending it a bit. Who sells a dogs whatsits round after a year?
As soon as he sells it he will probably be back on the beach in Thailand or Goa till the money runs out. Probably getting his benefits paid directly into the bank and renting out his council flat while he's away. That seems to be the general story.
Then when it does run out he will be back to Harrogate and canvass up another one. With loads of potential no doubt.
A fool and his money are soon parted.
