Well, if you have great credit you could always use a stated-income style niche mortgage. This is also known as a 'no income verification' mortgage. It requires a very good credit score (>740) and usually converts the PMI found in a normal mortgage (convention) to a pseudo-second interest rate. Also, because this is one that falls into a 'covered mortgage' its usually with a higher than normal interest rate.
For instance, let's say that you were able to get a loan for $100K at 6% with nothing down and PMI was the equivalent of another 1.5%. In an NIV loan, that rate would be +8% plus the pseudo-PMI still being 1.5%. I have a friend in this situation right now. He got his mortgage when the rates were about 7.25% two years ago. His rate is 10%. But, when you remove that pseudo-PMI rate it was like he had a mortgage at 8.5%, or 1.5% above the rate for a conventional mortgage.
Who uses stated-income loans? Well, these kinds of loans are typically used by those self-employed, or in sales, etc., where predicting their yearly income was difficult. But, this kind of loan can also be used by individuals that want to buy more home than the traditional front-end/back-end ratios (28%/34%) would allow for.
So, it all depends on several factors in determining you own personal situation. I know of one site where they have calculators,
www.mortgage101.com and I've used them to compare amortization schedules for refinancing considerations.
