Wraps, Downpayment & Investment Vehicle

Thanks to the Mortgage Adviser for reply to my previous post. As mentioned, I’m a newbie and have several additional questions.

On the subject of financing and wraps, I believe some vendors have restrictions on the purchaser renting the property to other tenants. Also they typically impose a 2.5% above the vendors’ borrowing rates. In light of this, how realistic is it to purchase a property using wraps, be able to hold and rent it to other tenants, and yet make positive cash flow?

If the wrap strategy is worth pursuing from a purchaser’ perspective, would appreciate views about who (reputable) to approach and where to look for such contacts.

Also, it seems that only the government can provide vendors’ finance in South Australia. Does that mean this method of purchasing is defintely a no-no if I’m interested in purchasing an ordinaly residential home there?

Are most people’s experience where they have success in investing typically partnering with others to cough up say 20% cash as downpayment?

I’m sure this question has been asked many times: is purchasing as an individual, as a trust or company the best method? Why is trust so popular as a vehicle? If purchasing as a company, the company is taxed at the corporate rate, and you as shareholder draw on the profits, won’t you also be taxed at the personal income level (additionally)?

Thanks so much for any help.
