In property investing there are no smoke and mirrors. Therefor if someone tells you something that sounds so complicated or advanced that you can't understand it; it is probably a smoke and mirror deal and worth your while to steer clear of. Further I put it to you that if it makes sense to you, thats probably because its on the level and conversly if it doesn't stack up; its not because you don't understand a valid concept; its because its not a valid concept in the first place. In short. Trust your instincts, they will serve you well.
The backbone of a property investors viability is a day job and a home. If you don't have these things I strongly suggest you aquire them preferably for several years before you buy an investment property.
That said, if you dont have much money and you want to generate some money fast, the way to proceed is to purchase your investment property 20% below market valuation and in need of renovation of a fairly superficial kind (dont buy a unit in a building that leans like the tower of Pisa!) splash on a coat of paint, renovate and tidy the garden and proceed to sell at a profit as quickly as you possible.
