As I do goal setting, what are some realistic scenarios, benchmarks, and targets to help with the goal setting? 

Just look for areas renting in around $800-$850/mo in lower crime areas.I always recommend networking in your target city and building a team.

I want to get into the Indianapolis market but am having difficulty targeting B to C+ neighborhoods with properties at $40k-$60k per door (rents at $800 or more a month).

It sounds like you are new to investing & the Cleveland area so I wouldn't recommend it as a target area for you.

Read all available information on your target market, median SFR price, SFR sales, MLS listings, sold homes, local economy, jobs, construction, rankings on case shiller index, etc.3.

(If direct mail, what are you targeting?

Most of tools I come across target the US market.

not if you target the right CC some of them are geared to no balance transfer fee but when there is a fee it is less then the interest I would of paid by a mile

A cap rate can be a great reference point, but is really only relevant to you as it relates to your clients goals for the property, target lease rate and if you are going to sell it as an investment. 

What property class – A, B, C, D – and niche – value-add, new builds – do you want to target?
