Trying to understand Conveyancing?

[IntrovertForReasons]

Dear All,
I am new to posting and wondered if anyone out there can help me?
Back in March this year after a very drawn out financial agreement culminating in a court order around divorce, I put my home on the market as directed in the court order. Long story short I had to accept well under the quoted price listed in the court proceedings. Anyway, having swollen that bitter pill I sort the advice of a mortgage broker.
I detailed with him the, what I assume to be, incomings and outgoings that I was asked for along with evidence. I was very specific about my financial worries around affordability and checked in with him, having paid his fee, on several occasions once I had identified a property I was interested in. He assured me on these occasions that, yes, I could afford this house and I made sure the monthly repayments were affordable too. I went ahead and employed solicitors to work on both the sale and purchase.
I understand that there is occasionally a fee discrepancy towards the point of exchange however my solicitors just last week, 3rd September, say I now have an outstanding feeling of £11495.00.
Of course this means having to go back and renegotiate my mortgage offer which I understand can take up to 2 weeks.
Has anyone any insight into whether this type of amount could have gone unchecked and if there is a fault who does it lie with?

Many thanks for reading.

Have they sent you draft completion statements? They will probably set all the items out.

Re the mortgage advisor, did you definitely give him/her all the details of the amount you’re getting net from the sale or could there have been some confusion there?

Without having some more info about the figures. it’s hard for anyone to know where the gap has come from. You’ll have things like estate agency fees on the sale and solicitors fees. Also SDLT depending on the price of the new place.

Edited as I read the gap initially as close to £115k rather than £11.5k which is more likely to be legal and estate agency fees plus things like Land Registry and search costs.

Yes. I paid solicitor all fees. They paid EA and all searches etc. You should get details of their service before they go ahead with any work.

Sounds like the SDLT and other fees, including the solicitors own fees, that are normally payable just before completion.
But this shouldn't come as a surprise to you - conveyancers usually send an instruction letter at the outset which gives the costs estimate, and then update you during the transaction if there are likely to be any increased charges.
The mortgage broker will have been looking at affordability from the POV of whether your income and deposit can cover the mortgage. The incomings and and goings you refer to would relate to your monthly budget.
But you must have known that if the price is x, and the mortgage is y, that you would need to factor in in SDLT, Land Registry fees , solicitors costs etc. Mortgage monies are used to buy the house. The associated costs are a different issue, not paid for by the mortgage, which would never be for more than 100% of the price ( except for a short period in the late 80s).
