You've still got be above 600-620ish for FHA, along with income ratios.

Startups can pull in loads of money without a solid plan for making a profit or sometimes any immediate income.

Lenders will use your tax returns schedule E to calculate your monthly rental income.

I like Rental income podcast and the rent prep one.

As Dave Greene always preach, you need to have a steady source of income while you grown your portfolio. 

My understanding is that Rentalizer overestimates both income and costs.

Both of us have corporate jobs with decent salaries, so we are saving about half of our income every month after all fixed and variable expenses and we have no plans to move in the foreseeable future.

If it's continuous income, I would look at 2-4 properties in great areas and leverage.

It's a great opportunity for my family to have some additional income down the road.But man, it is tough telling a young family with 3 kids that aren't going to be allowed to rent the house due to prior collections owed to landlords and vehicle companies. 

In your offer you can specify that you want access to bank records and tax returns to see and validate income/expenses.The challenge with whatever info you get, besides validating you aren't being conned, is what will your numbers be?
