With this technique you borrow funds to invest, and pay off the loan with incoming cash flow, then repeat. It can be a secured or unsecured loan. In the case of purchasing securities, you reduce transaction costs by making bigger purchases at one time, and buying more on dips. It will also help getting into investments that need more up front than your short term cash-flow allows. With a little practice your total return will be more than the cost of the loans.  This will help build wealth out of savings, over the long term.  After borrowing the amount intended to be invested during the period, the saver invests the loan-proceeds. By putting the "savings," out of reach, the borrower is forced to pay off the loans out of current earnings, which completes the saving process. 
Your total return includes dividends, capital gains distributions, and the increase in the net asset value of the property.  The total return is the change in value of an investment over the loan period, assuming reinvestment of any dividends and capital gain distributions, expressed as a percentage of the initial investment. 
Originally this took advantage of what is now known as automatic reinvestment of dividends plans. Compounding is the most powerful force of capital accumulation. Few people had access to shareholder plans and there were no IRAs. So the idea was to borrow $1,000.00. Invest the whole amount in one stock, and reinvest all dividends, and capital gains.  This was ideal for closed end funds and high dividend paying stocks. So they invested the thousand and paid it back at $20.00 a week. The usual variation on this was if prices were extremely low before you paid it off. Borrow again up to your limit and buy more shares cheaper. If this was done continuously you had dollar cost averaging in your favor also.
The Save by borrowing technique can be the quickest way to invest right away for people without savings. Without some external force to help, many people’s chances of saving enough money to invest are small. Borrowing gives users the chance to create a commitment to fulfill investment goals.
The basic issue is overcoming the difficulty in building savings for investment. While commitment features are built into most informal-sector financial devices, they are uncommon in formal-investment saving devices. One of the main services provided by nearly all moneylenders is an installment plan that matches borrowers cash flows with the flexibility to delay repayments when necessary. Lenders have a keen interest in the success of the transaction. But when you’re saving, you’re typically on your own, with little structure or support. If anything, family members and neighbors undermine saving strategies by asserting their own needs. The installment structure and the lender provide discipline and a measure of support. Interest costs function as a penalty for shirking, and increases the salience and urgency of repayment. 
The explanation for simultaneous borrowing and investing is rooted in the difficulties in saving for investment. Interest rates on loans may even be a desirable for some borrowers. This innovation commits Investors to building their investment accounts in lump sum investments with a flexible payment schedule. Individuals are often more impatient with regard to current trade-offs than with regard to future tradeoffs. The resulting time inconsistency undermines saving, since even if individuals feel that it would be best to save in a few months time, their choice to save gets reversed once the decision point arrives and action occurs in the present. Investors often do better by creating a commitment to invest now, which ties their hands, committing themselves to an investment plan that cannot be easily undone. 
Borrow, to lend, be surety for, to "borrow," apparently on the notion of collateral deposited as security for something borrowed. Pledge, security, bail, debt, to protect, guarantee, to borrow; to lend. 
What you are really doing is turning wages into capital, by paying off loans used to buy stocks. As your income grows, the current size of your portfolio can be used as your benchmark, with a goal toward adding a minimal percentage of the portfolio each month out of earned income?
As the portfolio grows the percentage can be adjusted to balance changing portfolio size, and your earnings. For example if you can invest enough so that you can add just 1% of the value too your portfolio each month, all things being equal, the portfolio would increase by an additional 12% a year. Two percent of the portfolio value added each month grows at an additional annual rate of 24% a year, which alone can double your portfolio every three years. The way to implement this is to look at your portfolio size, transfer whatever percent you plan to invest out of your periodic income stream to pay off your save by borrowing loan. As soon as you pay it off, buy more stocks with a new loan, or on margin, and pay it off again. Repeat.
Warren Buffet suggests investing in closed-end or index funds if you are not going to spend a lot of time investing. But goes on to say that once you are in the position of evaluating businesses, anyone working with normal capital, who is willing to bring the effort, intensity, and the time necessary to get that job done, owning six stocks is plenty.  http://www.bestcashloans.org.uk/
