Need advise on how to come up with payment for 2nd investment

[Sandeep Singh]

It always happens that the perfect deal just pops up when the finances are not there. 

180k for two family house. Estate sale

I own my primary residence with my father as cosigner. From this house I Took 50k HELOC to buy my first 2 family investment house at 235k.

The rent from this property pays the mortgage, taxes and insurance at 1640. Plus 380 for the heloc payment. I pay water usually around 80. Then I maintain the landscaping since I only have one rental. Both units are rented out at a total of $2700.  $600 left to play with. I had put down 25%. This deal happened this past December. 

The new property is @180k. What are my options to come up with funds? Can I buy as owner occupied and move out my current residence and live there for a year? This property needs about 25k of rehab. But the location is very great. It would easily appraise at north of $260k after the work done. Any insight is appreciated on what my options can be. The sellers have out it at a price that it will be gone immediately. 

Thank you
