Evil can you send me a copy of your tenancy to scour through? I got out of my last one with my psycho landlady as there was a clause along the lines of "Tenant should be allowed to habit property peacefully and without interruption" and another about "Landlord to give written notice at least 24hrs before visit". These are pretty standard so in theory, it shouldn't be difficult to find a reason to get out of the tenancy. Not sure about house-prices in your area etc but I can probably give you some pointers on the mortgage front too.
I hear you on the wanting to move thing. When I moved into this house it was a massive relief after all the grief from my old landlady to finally be able to call somewhere home without a landlord terrorising me. This house has been the longest I have lived somewhere since I left home - I have moved 6 times in 4 years
- and has been the only place since moving out of my mum's house that has felt like home. So now my landlord is being an absolute PRICK I am really hurt that that feeling of homeliness and security has been pulled from underneath me. I am soooo angry he has left me feeling unsafe and uneasy in my own home, and whilst I was keen to buy a house and move this year, I am furious the decision has been made for me. I did have a proper sobby cry about this last night

Congrats PP I am so happy for you!
I am with VQ on the toy front. Personally I didn't see £50 as extravagant for a one off memory piece. I am not normally a sentimental person but I am scarily attached to the memories contained in some of M's clothes. The amount of time, effort and energy it took the lady who made mine to make something so wonderful is worth so much more than £50. I charge almost that per hour for much less work, and out of that she had to take postage, materials, etc. I know I couldn't have made it.
