I too think it is a personal choice that will depend upon where you are in your investment strategy.  

i want to get into real estate businessfrom crash. can i get some beginners strategies and role and some encouragement  about the business 

Are there any other strategies for maximizing my cash-on-cash return aside from going for commercial loans (with variable interest rates) or doing creative financing options (such as subject-2 or owner financing)?

Once they say yes then I discuss owner financing and how to will help their investment strategies. 

Look up BRRRR strategy

Yes, cap rates are compressing but even at mid 5s to 6s, w/a value add strategy, comps below competitors in price / rents and realistic underwriting that expects caps to rise slightly w/increase in interest rates, you can still make a very good return.  

Thoughts on this strategy?  

There are calculators here to help modeling, but you need a strategy first. 

I've spent the past few months trying to understand the numbers, develop growth strategies, and learn the basics of being a successful landlord.

I need some experience with this so I recently started developing a strategy to find my first deal.
