However, I don't like the fact that properties they will show me, they will have a financial interest in, because it could affect my purchase negatively. what are the pros and cons of going with an agent that requires dual agency vs. not?

I know this is a rookie question, so please no negativity. 

Just remember: most negative reviews are written by problematic tenants.

I've seen many poor investments made with single digit cap rates and even negative cash flows in hopes of getting great appreciation. 

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.

Just remember: most negative reviews are written by problematic tenants.

Since we're not in this 100% for the invesment, we're okay with a slightly negative cash flow.

Essentially are you cash flow positive or negative each month?

Some positives and negatives to evaluate. 

They did what they said but it was pricey and the leads/conversions I got end up being negative ROI so I quit.
