Should I wait for vendors to pay for their survey first?

[JustAlice]

FTB here. I keep hearing about vendors in our area pulling out of purchases because they couldn't find/afford their "forever home", wasting months of their buyers' time and money.
Will it be rude to tell the EA after having our offer accepted that we'll start paying for survey etc only after vendors start the same activity with their onward purchase?
And who'll be making sure the EA is keeping us up to date about the status of the chain/suspected delays? Should our solicitor do it?

Also, if we make offers on multiple houses to make sure at least one of them is proceedable, can we buy homebuyer's insurance for all of them and get reimbursed on the ones that fell through?

Estate agents would not normally see you as a serious buyer if you make multiple offers to various properties. It shows vendors you are not serious and they might choose another buyer for their house. Surveys usually don’t start until the chain is complete so you wait for this and then everyone starts spending money at roughly the same time. That’s how it is in my area of London anyway.

@LoveWine123 thanks, after reading the threads here I was under an impression the buyers are expected to order a survey after the offer was accepted, regardless of the chain status, otherwise they are not considered "serious".
There's a property I'm interested in, but I know from a neighbour that the vendors have pulled out of sale before because they couldn't find what they liked, and I'd like to avoid vendors who are not really motivated. There's a lot of people like that in the "houses are not shifting" thread.

OP - 'making offers (and assuming they are accepted) on multiple properties' is doing exactly what you are complaining about - mucking people around by pulling out down the line. Of course you can do that if you think that's appropriate, but you are being very selfish and some EA's will quickly pick up on your lack of integrity. But the reality is you won't have lots of offers accepted.

Find what you like, offer, get that accepted and follow the process. OR, move to Scotland - their system is a better fit for you.

This is so weird - you want to avoid non serious buyers for your own house but want to put in multiple offers so therefore be non serious buyers for other peoples houses? Unless you are very rich and plan to buy all the offers you put in which are accepted?
