But, even more importantly know your limits stay within your means and comfort level at first don't take on to big of a project and get overwhelmed.

I will be looking for entry level under 5 units in the next year and will be looking to get into apartments within the next few years.

The rule of thumb is 50% of rent will go to expenses NOT including debit service.

Bedrooms aren't horribly small - both units are split level units, so it looks bigger :)

And thank you for your service!     

No Land Contracts or Contract for Deeds.I also use a 3rd party payment servicer.  

It is also true, the better the website, the better the response, and there are a plethora of web site gurus out there offering services to those who need them.

Having a separate checking account for each house just doesn't make sense at this level, so am I just stuck manually figuring out what house each charge goes to or is there a better way?

Also a recommendation for a decent servicing company for small loans would be helpful as the payments are not as big so fee's could eat profits easily. 

Once you're able to communicate with the property owners, the servicer on the note can contact the note holder to see if anything can be worked out.
