Bank lending and debt/income ratios

[Ryan V.]

I am looking to get pre approved to purchase more investment property. I would prefer going through a national bank because they offer amortizations up to 30 years, but I am not against going through local banks because that it what I have done thus far. One only goes 15 years. The other will go to 20. I want the option to go to 30.

I currently have a 8 mortgages. I have one mortgage on a mobile home park, three mortgages on three sf homes through a local bank, two mortgages on two homes through a private lender, one mortgage on four units through a private lender, and one mortgage on 5 units in an LLC through a local bank.

My credit score is over 800. What is the bank wanting to see as far as debt to income and other criteria. What's the highest debt/income ratio and how do they determine that. I have been a landlord for seven years and all income/expense is documented through tax returns for each property for at least three years. All my income comes from rent from rental property.

Do banks only take a certain percent of rental income when figuring my debt/income? Basically, how are they going to analyze me?

Thanks for any help!
