Or they're buying it without even viewing! If I manage to get a viewing and put an offer in I have been beaten by cash buyer on 4 separate occasions, each time I've put an offer over the asking price.
Yes, have been buying buy to lets and the last 2 years and houses are literally being sold within an hour of going online.
House up the road from me, sold on the first viewing for 25k over asking.
Ive just picked up a BTL flat, I was first viewing and my instinct was to offer less as its in a right state, but just asked how much to do a deal right here and now, got told the figure and said "done". No point trying to haggle at all.
