It's no guarantee but it's a good place to start.

No income no doc .

Since we have zero income, I'm not inclined to pay a CPA several hundred dollars to do our taxes, so I'm trying to do it myself. 

What was offered to me personally was a DSCR loan, since it's based on rental income of the property you're trying to get a loan on, not previous and current personal income. 

Feel free to reach out if you would like some income comparisons.

But if I can't sell quickly, I could rent them and have multiple cash flow (because of the different income sources of the different tenants in the same unit) and wait for the market to recover and then sell the unit.Please let me know your comments and suggestions about this information.Thank you everyone!!

Cashflow=Rental income- expensesRental income: how many rooms will you be renting out?

While you may be able to make 200/door you probably lose that with lower appreciation.I would run some numbers on new purchases in Denver and one or two Midwest markets (using zip codes for household income to identify your b- neighborhoods) and see what makes sense.

I'd ask for the rent roll, or income statements.

A DTI (Debt-to-Income) ratio of 50% or lower, when including all expenses you pay/month, would be safe IMHO.
