On a parting note, anyone who owns 25% or more of a business and is using mainstream financing will be required to provide tax returns as they're considered self employed (portfolio lending can do whatever they want).
I've seen some very rare cases that Desktop Underwriter will only ask for one year of tax returns. While it may be possible this could work, many lenders will have an overlay to require two years of returns even if DU asks for only one. It'd be a good idea to go into this with this expectation and if you get lucky, great, if not, you wait a year. I know as of when I write this, my company can do this but none of the companies I've worked for in the past five years can do this so it appears to be uncommon at best.
