Don't buy any rentals in London UK, you will never be able to evict ...

@Raden Mantuano not only are you having to bank on appreciation, you are gambling on where interest rates are going to be in 9 years.

Or is it a gamble and the original owner could come back and reclaim the home?

Sell to my long-term tenant for $400,000, and invest proceeds in stock market, while avoiding new roof expense in a year or two and taking a gamble on new tenant when current one leaves if I don't sell him the house.2. 

Hello, new to REI currently an expat in the UK and looking for a market to invest in the states for LTR.

Other investors gambled, overpaid, negatively cash flowed, and got wiped out.

Real estate is a big lumbering elephant compared to the nimble stock market, but it's still a gamble to wait to time the market for downturns and upturns.   

Buying a home with the idea of selling it (at a profit) is more of a gamble than a strategy unless you buy something with the intention of doing a live-in flip.

Yes our research says that it would be a gamble and not  much cash flow if any at the1500s.

And what kind of gamble are we investors making, when most MF loans are only locked in for 5-7 years?
