Off-Market Opportunities in Mayfair and Marylebone

There is currently well over a billion pounds worth of properties available off-market in Marylebone, Mayfair and St James’s.

While many believe that only properties over £10m are ever really sold without appearing on the property portals, this is far from true. Several properties between £1m and £5m are sold privately.

Another misconception about off-market properties is that they are all overpriced. This is certainly true in some cases, but would it be unfair to say that many properties on the open market are also overpriced?

So, worrying about how the properties are priced is not a valid excuse for failing to look for off-market opportunities. Indeed, the key is to understand what motivates owners to sell off-market (there are several reasons, some of which will surprise you) and then negotiate accordingly… and one obvious upside is that you are far less likely to get involved in a bidding war if a property is not being openly marketed.

So, would it be a bad idea to give yourself a massive advantage over other buyers by having first refusal on these exceptional properties?

There was one property that really stood out for us – a 4,500 sq.ft. house close to Sloane Square that was wider than average so only over four floors. It ticked just about every box we could hope for and wasn’t on any of the property portals, so we would never have found it ourselves.” Mr & Mrs Cole

Jeremy quickly sourced a selection of properties which met our requirements and one in particular stood out – a stunning Georgian house which was much wider than the standard London home and which also had exceptionally high ceilings. The house was not on the open market so we would never have known of its existence.” Mr & Mrs Ybarra
