Zuby - they will prob only look at you if you move your whole portfolio. I have tried various projects, for instance I currently have a freehold flat and a large 4 bed house with no loans, I also have 3 other properties with low loans, I am considering doing these in a bulk lot but realistically you want to be lending over £500k.
Depends on area but most banks have a property specialist and they lend on different criterias, I use Lloyds and the lending criteria is to have over £2million in loans - then you use a Director of sorts who is much better and can ALWAYS get you money more or less.
I know Barclays in the North West have a criteria of only £500K so it all depends on how much you want. Most banks on a smaller level are really struggling this is because they would rather lend to people who really know what they are doing and have lots of security, you get about 60-65% of the value.
Banks I know that are lending are Handlesbank(50% LTV), Barclay's and Lloyds(60-65%), Bank of China I am told. HSBC may be coming back in I am told but have had no dealings with. I am told Lloyds is the best and doing the most deals but I have been with them for many years and was lucky in that respect.
