I personally have friends who are horror movie and Halloween fanatics, who would see it as a bonus.

Two partners have corporate jobs with good six figure incomes, bonuses, 401(K), etc. and I am a real estate Broker who focuses on my transactional business (six figure income), plus I am a retired police officer with a tax free monthly income (Approx. $54,000 passive income per year-tax free), so we are covered on our living expenses.

The other bonus is low cost vacation options for the fam.

Ask them to refer a friend/family member and you will give them a bonus.  

Some have better bonus depreciation than others and multifamily is certainly a good one!

Plus I get the added bonus of diversifying my money into multiple units (since property prices are much cheaper in the midwest).

I have started saving like $100 a week on food while eating better(Bonus!).

If you have sensitivities to the neighborhood or people, then maybe charge market rates and give them a bonus at the end of their lease when they didn't screw you over or destroy your place.

I will be giving my PM a bonus if I can locate, close and rent within 45 days at 10% CoC return.

I would also include roughly 5% for vacancies, 10% for property management(bonus if you do it yourself), and roughly 7-10% for maintenance.
