It's possible but not in your current structure unless you look at a pension backed mortgage, you need to seek advice, property can be bought directly through an ssap but you will have to meet all requirements including arms length rules,you can invest in syndicates etc through a self directed pension but this is different to owning the property yourself. In my opinion unless substantial amount in your deferred scheme (enough to buy the property without borrowing through the fund) you will find it difficult to do.
