I'm afraid that owning property in the UK does entitle a person to be eligible to apply for ILR on this basis alone, nor does it entitle a person to any kind of long term visa status.
If you wish to stay here on a long term basis then you would normally apply under one of the points-based systems for a workers visa, but I'm afraid the recently imposed cap on Tier 1/Tier 1 applicants was reached in December and no new applicaitons are being accepted until further notice.
You should check the UKBA website to see if in principle you are eligible to apply for any of the points based system visas. Here is a webpage, you can reach the necessary information by linking at the bottom of the page
If you think you do in principle meet the eligibility criteria then I would check the UKBA website for news updates periodically about when the cap is to be lifted or revised.
Sorry it could not be better news. I'm afraid it's a very difficult time for non-eea nationals wishing to come to the UK.
