All three houses are in the same tax class, same neighborhood and all around similar.

Then I run credit report and see they both have multiple accounts that went to collection (mostly medical bills) and the man has 2 convictions in 2015, class C misdemeanor for possession of drugs and driving while license invalid.

They are often paying $300 or more per night so I have a higher class renter.

I've been to a few seminars for RE investing but always walked out feeling like they were trying to sell me a get rich quick scheme or sign me up for 20K dollar classes.

Err on the high side if this is a C- or D-class neighborhood.4.75% interest seems low for a non-owner-occupied property. 

You may have to share some of the profits but it is a much faster way to scale.Some other benefits are:1) You can spread your risk by investing in multiple deals, geographies and asset classes (Multifamily, self storage, etc.)2) You are gaining leverage by partnering with people who have got skills, relationships and time that you don’tGood luck!

I've seen classes for around the 500 mark which might be worth it in the long run maybe? 

@Lee Prado the in person class was great and totally worth the money

Financial advisors (the fiduciary, holistic ones at least, work well on advising across asset classes and longer term financial planning.If you're clear on your investment game plan, a solid CPA, like other commentors have mentioned, works well.

., but you have to be careful because I find most of the people selling coaching, classes, etc are amateurs.
