What to do when you have excellent credit but cannot show income.

[Glenn Martin]

I have four properties, two in NYC and two in GA (one is my home and one is self-directed IRA). Collectively, they're worth $1.3 million, all paid in full. But, I recently left my job to do consulting and I have less than a year as an entrepreneur. Hence, I cannot show income or qualify for an investment mortgage. What do I do, given that I want to continue to buy properties for passive income? I've looked at hard money no doc loans. but 1.) seems a shame to go that route when I have so much equity and credit score of 830 and 2.) it's EXPENSIVE and leaves little room for profit. Any ideas?
