Does this sound like a great idea regarding being a landlord and starting a real estate empire?
I have done something similar to this myself.  What you are suggesting is a sound theory and it works.  The issues are (which is why it's the reason not everyone does it) : The initial cost is great, many people in their 20s or 30s cannot afford their own home, let alone buy second properties.  The time to build up a portfolio is very long term and is best for a pension investment.  it's often not best for diversification - you've heard not putting all your eggs in one basket? With property deposits, you need to put a lot of eggs in to make it work and this can leave you vulnerable. there can be lots of work involved. Renovating is a huge pain and cost and you've already mentioned tennants not paying!  unlike a bank account or bonds/shares etc.  You cannot get to your savings/investments quickly if you need to (or find an opportunity)  But after considering these and deciding the plunge is worth it, I would say go for it, be a good landlord, with good quality property and you'll have a great nest egg.  If you try just one and see how it goes, with population increase, in a safe (respectable) location, the value of the investment should continue to rise (which it doesn't in a bank) and you can expect a 5%+ rental return (very hard to find in cash account!)  Hope it goes well!
