Financing a second property

[Ross Bernard]

I recently purchased a 3BR house and am renting two of the bedrooms. The PITI is $900 and their combined rent is $945. My income from my job is about $2300/mo after taxes. My question is, how difficult will it be to obtain financing for a rental property? My (very limited) understanding is that the bank will ignore my current rental income and potential income from the second property. So if I had a $900 monthly payment on the second property they would see it as $1800/mo in mortgage expenses versus $2300 in income and deny the application correct? I feel like I must be missing something.
