It's not foolproof, nothing is, but I've won plenty of deals that way.

Nothing is foolproof, however, so carry a good umbrella policy -

Quote from @Liam Kingston: When it comes to protecting them, having your LLC name attached can help, but it might not be foolproof. 

Safety, seek less risk"I hear this a lot.You want safety but yet want a bunch on cash on cash return.The more return you want the more riskier things become.For instance a fully performing multifamily building in good shape in my area you might land a 7.5 cap,semi-performing 10 to 11 cap going in,totally vacant apartment building high teens or more in cap returns.So again the more risk the greater the reward.REITS are not fool proof either.Many of them have lost money in the last few cycles.Would you be happy with an annual 7% return being in something safer with a tax write off with annual inflation being at 3%??

There are ways to deal with this (including the injury liability issues) but they are not foolproof.  

, but its always a sobering reminder that its by no means a foolproof way to financial success.

This is not foolproof, but it can be pressurized with an air compressor at low pressure, about 50-60 pounds.

No screening is 100% fool proof, but it's also true that there ARE good tenants out there.

Concentrate on what you know and  changes you see - you will see a major change coming long before I ever will,  long before anybody else will, because "X" is your passion; they are  what you are sitting around reading about all the time.2) You should  wait until you find something you are so thoroughly sure of, based on your  wealth of knowledge, and something that is so cheap, that buying it is a fool  proof as going over to the corner and picking up the money.

They hear what they want to hear and fall for the flash over actual substance.I'm not saying this method is fool-proof, but it's Step One of smart due diligence.
