It's not guaranteed or foolproof, but it takes a long time and a lot of interaction to generate large numbers of both.

I am simply addressing your stated desire to retire at 65 - and this is the most fool proof way to get there.

Happened too many times for first 3-4 years.There is no risk of loosing the "deposit" either and it's just a bit of skin in the game even tho the skin is always yours to keep heheCovered all angles mate and made this as fool proof as possible but still enough to make folks "jump" through hoops to see who is legit and who isn't.As Chris mentioned, 90% of investors we don't end up working with and even when many commit to the deposit, I refund many times as I don't feel a good fit.Even with such stringent criteria, we still get mud thrown on us here on BP as some folks slip through the cracks.I could only imagine if we took on everyone and just focused on pushing sales.I can sell a TV to a blind man and ice to an eskimo.

They are not intended as fool-proof guarantees. 

I usually get 10% interest, and I can sell the note if I need the cash back (at a discount of course)     It’s not fool proof, but when done correctly I consider it to be one of the most safe, and profitable, of any investing strategy. 

I have a 100% fool proof solution for this.

I believe a great strategy for Tenant Screening, other than the usual Background/Credit/Income checks, is to get a letter of recommendation from the current Landlord AND, at the same time, PROVE that they have paid their rent for the last 12 months ON TIME and are CURRENT on their rent.While no strategy is foolproof, this one prevents getting a letter of recommendation from a Landlord who just wants to get rid of a bad tenant.Bad tenants probably 95% of the time are not current on their rents and certainly do not have 12 months of on time payments.While I didn't implement this until recently, one of my tenants that is searching for a cheaper apartment was asked to give proof of on time monthly rent payments while I gave him a Letter or Recommendation.In other words, the on time monthly rent payments corroborated the story given by the Letter or Recommendation.While I haven't had a tenant issue for the last decade, I do believe this is a GREAT strategy to try and weed out bad tenants.From now on, this has become my policy.I also let some of my tenants who have a habit of paying late that their Rent History is very important and they should treat it more important than their Credit History.If you can prove you have a great Rent Payment History, dings in your credit which may have come from something like a Divorce, etc. can be looked at in a better light, or so I believe.All my tenants are on an online Payment System, Rentalutions.They all have access to their Payment History and can produce a report.

I read "The book on property investing" by Brandon Turner an in it he says to make adds fool proof so that applicants aren't calling you to ask "how much is rent" or "how many bedrooms" etc.

Nothing is foolproof, of course, and that's not to say someone with a ton of votes or posts can't/won't be wrong on some issues, but in a virtual world where vetting is difficult it's as close to a sure thing as you can get.
