Hi everyone - hoping someone can shed some light (sorry for the essay).
I'm in the process of buying a shared ownership property, but we're 4 months down the line and there's still no sign of a moving date. Basically, everything that could have gone wrong, has gone wrong, but no one is accepting any responsibility and I'm the one left out of pocket.

1. I was misinformed from day one - I confirmed with the Estate Agent 3 times that the lease was 900 years. 2 months in, the solicitor got involved and told me it's actually a short lease with 85 years left. From what I've read, if it goes below 80 years it becomes harder to sell and/or I'll have to pay thousands to extend the lease. Estate Agent issued a non-heartfelt apology and basically said 'you either want to move in or you don't'.

2. Parking - from the moment I viewed the property I was told the parking outside was mine. Turns out two spaces right outside my kitchen window are public and not mine at all - again, found out by the solicitor 3 months in.

3. Boiler service - the boiler is dead old, which I knew, but I was told by my EA that the seller was going to service it before the exchange. I chased and I chased and was told the seller was let down by a couple of plumbers. I then got a letter through from my solicitor saying the seller would not be providing a boiler service. So my only assumption is that my EA was lying and hadn't confirmed it with the seller at all. This means I now have to pay for the service (on top of the ridiculous premium the seller has added to the price of the property).

4. The most important one - the mortgage! As far as I was aware, I'd secured a mortgage with Nationwide and it was all going through okay. Now, over 4 months in, Nationwide have retracted their offer because I'm paying a premium on the property. Apparently they don't offer mortgages on shared ownerships where there is a premium. I was never told this would be an issue, so I'm annoyed that I'm only finding out 4 months in. The Estate Agents have blamed my solicitor, saying it's their remit to relay this information to the lender, and my solicitor is blaming the Estate Agent, saying it should have been made clear in the initial application made by the mortgage broker as they (the solicitor) could only approach the lender once they'd received all the paperwork from the seller (which took month!).

Now I'm facing a mortgage with higher monthly repayments, the possibility of needing to pay out to extend the lease, to shell out for a boiler service and possible a new boiler - and all this IF I can actually find a new mortgage. I'm tearing my hair out a little and I feel like no one is taking responsibility.

I'm just fed up of being led a merry dance and told "Oh sorry about that..." and then being expected to just deal with it.

Do I have any rights at all to complain? (I daren't do anything yet because I don't want to jeopardise the process any further!)
