Well not everyone has access to a top bloke like yourself!My friend went through a Buyers agent and showed me the report. They would calculate the realistic value of the property & likely rental income. In essence, stop you from overpaying & find a property for better return.
Sure you can easily do yourself but doesn't sound like Dezz can be bothered.
The cost? A few percent of the purchase price of the house. So expect around 5-10k for their service, but the upside is the savings they can negotiate at auction.
I haven't used one personally but I spent every weekend looking for 4 months.
