I've since gone back and read the private money financing section in my books and have watched a few seminars online but I'm still a dear in the head lights.

I've been a general manager for 12 of those years managing 200-300 people, in charge of 10 department heads and millions of dollars in inventory.

I have noticed a lot of 2-3 flats with 2br units, thanks for the heads up.

Keep your head up!

I'm in an office by the Glaxo head office next to the M4 flyover and happy to have a chat if you are passing?

If you got it at a steep discount, then they could even more claim that you might have taken advantage of them (they might have been desperate at the time and were very happy with you buying) and now that they've got their head back together, they think that they should have gotten more money from you and become adversaries. 

I weighed contacting the head broker and letting him know that I am less than happy with the service I have obtained so far....

Dive in head first, educate,educate then educate some more.

Have you head of them before?  

You hit the nail on the head in your last paragraph - forget about trying to figure out how much they have in it and just make an offer.
