Offer Form - deposit at offer stage?

[2023Tobeornottobe]

I am selling my flat (about to put it on the market stage) and I have seen a house I really like (sold by the same agency as I am with). They have sent me an offer form as I want to get the ball rolling by putting in a cheeky offer. The offer form is asking me how much I have for a deposit. Does this mean as I have not yet sold, I put nothing? I have savings which I could use as a deposit (up to 10%) should I put that in the hope it would swing the seller in my favour?
To add, once my flat is sold, I will be a cash buyer.

I would cross out and put ‘no mortgage required, cash buyer on sale of property.’ It’s only an info gathering form from the agent.

If releasing the cash to buy the onward purchase is dependent on selling the first property, then you're not a cash buyer- you're just a buyer in a chain. You may not need a mortgage, but you do't have the money sitting in the bank at the time of buying the other property.

That's what I thought. Not cash buyer until sale of property but I am able to put 10% cash down upfront - should I mention this?

You will need to be able to put a 10% deposit down at exchange of contracts. Unless you are paying less for your next property you will not be able to send 10% up from your buyer. If you have 10% in cash, say so. If not, don't mislead the seller.

Seems like they are just trying find out how much you would need to borrow for a mortgage and what the LTV would be. If you will be cash buyer after you sell then I would just write what the PP poster said about no mortgage required. If you aren't on the market yet though I wouldn't expect any offer to be accepted as you aren't proceedable at the moment.

You don’t need to pay an exchange deposit if you’re both buying and selling - only the bottom of the chain does that.
