I don't have a rental property, but had a similar experience, trying to evidence the level of financial support from my hubby.
Is the property you rent out jointly owned? If it was only in your husband's name, you could give Erudio evidence of that and it can't count towards your income.
But assuming it's jointly owned, I would give them your last 3 months' bank statements, showing the rent being credited, but also show any debits for expenses that can be offset (mortgage, insurance, etc). Black out all other transactions they don't need to see.
Make it clear that only half of the net income is yours, it would help to draw up a spreadsheet (showing the rent for each of the 3 months, less expenses, divided by 2) and include that. Might be an idea to provide evidence that the property is jointly owned too. I've also seen other posts where Erudio have requested a copy of the rental agreement, really don't see why it's necessary and probably a stalling tactic, but if you're ok with including it, it might help speed things up.
Hope this helps, good luck!
