Mortgage with lagging income to show

[Nick H.]

Me and my business partner run a short term rental business that's profitable as of this year (yes, surprisingly, despite covid). We have 35 units. We both quit our high paying jobs last year to run this full time, so last year we have income to show, but we don't have that W2 income anymore. 

We have assets (we own 11 units) + income from our short term rental business. However, since the STR business is only profitable as of this year, we don't have tax docs from last year that show income.

Without current W2 income, we've had issues security mortgages. Any advice would be appreciated!
