But it is just physically to far away from my base of operations for my current business style. 

Money spent on physical infrastructure outside of improvements for educational purposes does not receive any tax advantage.  

I would guess I physically inspect 5-10 properties for every one I make an offer on and I may only get under contract on 25-33% of those because I typically offer aggressively so my numbers work.

When you work six days and take the seventh off, your physical, spiritual, emotional, mental and even your financial health will greatly improve – and so will your success rate.

Then use your due diligence period to dig into the operating data and physical condition of the building to make your final decision.From what you posted, it sounds like it could be a winner.Good luck.

@Atwan Kwan Did you physically inspect the property and verify that there was only one cat? 

I'm currently looking into real estate investments as I am fascinated by the thought of monthly income through rental properties.To get to know me better: I'm currently 19 years old,  a physics student living in Germany and I just read an article about seller financing.Would it be possible that I start investing in rental property or do I need a real job first/assets?

Then lookup the owners contact information on the New Castle County Parcel Search and send them mail pieces (if you don't have the money for this than physically show up at their house and knock on their door), letting them know you're interested in purchasing the house. 

But, from a conservative analysis point of view it's where I would start until you can physically walk the property. 

All things being equal physically, I would go with more units under one roof.
