Input on Using Rental Income from Primary Residence

[Alex Agafonov]

Relatively new investor here!

I purchased a single family home in October 2014 and have been renting out 3 of the 4 bedrooms ever since. This results in a monthly profit of $427. I am currently on a plan that would allow me to purchase a 2nd property in the next 15-18 months. However, it would be hard for me to qualify for a second mortgage based on my monthly income and I want to take my rental income into account as this is an additional $5124/year and can offset the mortgage from my liabilities. 

I am now in the process of filing my 2014 return and due to the limited number of months that I rented the property (November/December), the number of deductions that I am able to take from the home purchase and a few repairs that I did prior to move in, my rental income is showing as -$3300 for 2014. Will this create issues for me moving forward? What is the best way to handle this? I am willing to limit my deductions to show a more positive rental income number. 

Thanks in advance!!
