Re Newbie's and NMKC's posts above...
Indeed I think this is responsible for much of ordinary folks fascination with property and BTL... the fact that mere mortals can get access to leverage. And if you want to get rich, leverage helps enormously. Of course it's not without risk... e.g an old school chum was bankrupted back in the late 1980s/early 90s when they they overextended themselves attempting to grow a property empire. What did them in was the last significant episode of falling house prices and "negative equity"; but for now the "everything bubble" floats everything ever upwards.
Once you have enough in liquid assets to secure property-sized purchases on your portfolio, some interesting things become possible with margin loans. The blogger "FireVLondon" has had quite a lot to say on this topic. See e.g
https://firevlondon.com/...ars-of-the-margin-loan/ but it's a recurring topic with them.
