I agree some people do leave trash all over instead of putting it in the trash cans.

I agree with @Jonathan Greene here that the first step is thinking through what to do with the primary residence - you might try this tool that I built a few months ago to analyze whether you should keep or sell the primary residence! 

Hey @Kendrick Seen - I agree with @Jonathan Greene that it's most important you use it and use it well.With regard to real estate specific software, we really liked RESimpli. 

Agree with above.

Otherwise, it is what we call a streeeeeeeeeeeeeetch.I agree.

Just make sure any new lease terms are clear and agreed upon by the tenants.Nonstandard Rental Provisions: You can add provisions requiring tenants to pay for cleaning services if they can't keep things up to standard.

I also have helped place tenants in section 8 properties as a volunteer with nonprofits etc. and agree that they tend to stay pretty long.

@Alex Powers I would probably agree with this.

Depreciation I am less concerned with as I agree, based on what I understand, it's lowering taxes now, which will have to be paid later when the house is sold.

@Harley Kendall, I agree with most of what @Jonathan Greene aid with one exception.
