When you say in exchange for cash flow, what exactly that consist of, are you saying to offer them part of the rent flow on top of the monthly payments?

You need to be able to show that you accepted/rejected tenants based on consistent factors.

.-  W2 income is a necessity until you get a consistent portfolio of properties producing gains.-  Also diversify your debt with multiple sources.  

It is much more important to have one good buyer that does volume and can consistently close whenever a good deal is presented, then to have a lot of pretend buyers that cant close. 

I'm wondering if anyone here can explain the reasoning and comment on the formula's validity.He says, "The precise formula is that your loan-to-value ratio multiplied by your annual constant must be lower than your cap rate to get positive cash flow"so that's,LTV * C < CapRate --> positive cash flow(C = Annual constant)He goes on to define the terms like so,LTV = Loan/ValueC = (annual payments) / (loan balance)Cap rate = NOI / Price NOI (Net operating income) = income - expensesIf you do some algebra you can restate the formula as,(loan/value) * (price / loan balance) * annual payments < NOI --> positive cash flowBeing somewhat simple minded I would have thought that the formula for positive cash flow would be simply,annual payments < NOI --> positive cash flowBut I don't understand the multipliers on the left side,(loan/value) * (price/balance)Can anyone explain to me why they should be considered?

I have heard of doing BPO's or rentals, but was wondering if there are other ways that you can make a consistent 300-400 extra dollars per week?

Just communicate what is expected and understand that enforcement is hard but its easier that having to deal with the large  headaches of not being consistent."

If you are going to make up a calculation and use it in a manner not consistent with the proper use of a cap rate why not name it yourself instead of confusing people that don't know the difference?

I've looked at a number of these codes and they're pretty consistent. 

Consistently.
