The goal is not to evict but to get them to pay but you need to protect yourself and sometimes tenants need negative reinforcement.

I can imagine it going the other direction really quickly if you get "negative" section 8 tenants and a poor Housing Authority. 

The numbers provided are cash-flow negative so that doesn't help.

It is a simple question, one many of us see, but it is an advanced concept for flippers and knowing how to work within seasonality if it is a factor in your market.  

I also don't know if this is creating such a large cost, that it puts us more in the negative and makes it not worth it. 

I just completed my first rehab deal, and I still cashflow, but I can't afford property management without basically negating the rest.

For me if someone has a negative review I typically consider something else, if its positive then I would continue to do my own research but do not really go off of others.

Recent purchases are almost universally cash flow negative.  

Like @Michael Quarles and @Kristin Flores-Brockman are saying here.Occasionally there are investors who acquired an investment property with the intent to hold and put renters in, but find some unexpected negative catalysts that will impact their ability to rent it out.

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.
