I’ve made an offer on a flat. How much negotiating is enough

[Herbert Augustus Chapman]

First time buying here with mortgage.

We offered 10 grand less he will take 5 less so I will go back with 7000 less so 2 grand lower than what he will go for. What a crap way for me to explain it.

Reason being there are potential future lease renewal costs

be ignored. Their is nothing 'potential' about future lease renewal costs. They are guaranteed AND considerable.

It is also a buyers market so stick by your very reasonable offer. He won't be selling it any time soon.
