What are we doing wrong!

First post from a lurker! We’ve been viewing lots of houses since the start of the year and have since made multiple offers only to see them get rejected for various reasons.

I can make peace when they’ve been rejected because the seller had offers that were higher or cash offers but this morning we had our offer on a property rejected, despite it being the highest offer by some distance because there was better rapport with the other offer and seller.

What more could we/should we have done? We were only shown around by the estate agent and made an offer 2 days later having never been given the chance to meet or speak with the current owner.

It feels a bit soul crushing!
