The company has been in operation for multiple decades, has great client loyalty, and consistent revenue and earnings.

I see it and have to deal with the extra time and effort needed to work badly structured and submitted offer after offer, house after house.   

I have good W-2 earnings and a 800+ credit score.

Okay, let’s see how these same properties work for them, assuming everything else is the same:Essentially, they’ve created a $30k annual earned income on these 11 properties, which can be used to pay executive salaries, and passed on to shareholders as dividends—and they’ll earn another $300k in capital gains if nothing extraordinary happens--and remember, AH4R alone has over 50,000 homes in 22 states.It sounds like a license to print money.Risks do exist for these REITs, though.

As to tenants taking care of you, that really changes from tenant to tenant and if someone is asking for extras now then they're likely going to start asking for more and more in the future. 

Remember, prices have to drop by more than your ROE per year just to make your extra work worth nothing.  

If so, i bet they would like to continue to earn your business via new acquisition purchase commissions.

I love the idea of real-estate and need some extra money so I might try flipping or wholesaling while building money to find a house to make into a rental.

The two best ways I’ve found to fatten the bottom line is via fees or reduced turnover or repair cost.Pet rent, lawn care fees, and things that breakdown due to tenant usage are my go to items.Number of bedrooms, extra features are only a selling point.

Your reputation is also a big consideration that is worth more in the long run than a few extra dollars right now.
