Well, if it really is the dream property, I would briefly and kindly say a few words to the lady, and then eventually she'll give up.
ok, you have to weigh it up... I’m more of a principled person :)
And if we’re honest, my dream property is usually also the dream property of many other prospective buyers. And if the good piece has been sitting like lead on the shelf for 2 years, I would check and look twice and thrice. We spent a good 2 months intensively on our property, well we had the time... and then were rewarded. But you don’t always have that much time.
Our experience was generally that properties that immediately caught our eye and had already been on the market for a few weeks always had a catch. Interestingly, 2 of those properties that we had shortlisted are still available.
Applying pressure is a popular tactic, but only up to a certain point. Strangely enough, the agents/real estate companies/banks always needed three asks when we wanted to reserve for safety for 2 weeks. Also a selling tactic. Theoretically, they could have given us 1 month, it wouldn’t have changed the sale anyway.
Therefore, my well-intentioned advice... So examine carefully who binds themselves forever. And for God’s sake don’t create panic or think there will be no properties tomorrow.
