The issue with section 179 expense is that you normally have to operate at positive income.Under most circumstances, bonus depreciation is better since you can take bonus depreciation even if you operate at negative income. 

Would there be a certain area that may impact the business positively or negatively? 

Most that have negative feedback about the product are not educated about it.

Also, it lends itself to unconscious bias because we are more likely to view negatively people who are different than us.

I would try to verify the negative information and if in fact true, then it would be a pass for me.

i agree that a new purchase at 75% equity will typically not have significant cash flow and may even be negative when properly allocating for all expenses.Investing to max equity without reserves is risky and you indicate would result in stress.  

I am discouraged but by no means stopped by my negative experience with Jerryll Noordan.

you're going to be INvesting for the first few years... rental income from the property isn't going to start paying back what you spend in closing costs, rent ready costs, stabilization costs, down payment, etc. for several years at a minimum.hope this helps - not trying to be negative, just realistic. 

Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560 (almost 30% probability of default), little to no good tradelines, lots of collections & chargeoffs, recent evictions.

You're likely cashflow negative for the first few years.
