Hate to go all radderfire on you, but have you thought it's the ones that don't understand that allows the ones that do understand to make profit?
As professional investors label rental investors as "dumb money"... they try to cash in on rental investors mistakes.
If someone isn't going to bother looking at different mortage rates, the are allowing the bank to make less money on those who do shop around...
Heck if I knew what I did now... I wouldn't have used the 5k my mum and dad spent on a car for me when I was 22 years old and slapped it into the s&p 500, the investement would be 641.73% return @ £37,588.12
I inherited about £60k when my mum died, I was about 25.
I blew the lot.. Fancy holidays and a car and a load of mods for said car. Plus a load of partying.
Total waste of money in retrospect... If I had even invested half that conservatively , 20 odd yrs later (now) I'd be rolling in it.
If I was to be there again.. I'd still do the same but on a smaller scale and invest at the same time, as I think it's important to 'live' and have some fun but I wouldn't have really missed it if I'd have invested a decent chunk too.
