Considering some SFR properties in Cahokia / Cahokia Heights, Illinois and looking for some recommendations on inpsectors in this area that do a good job looking at multiple properties

That is why most of them just let us do our jobs. 

If your student loans are only 3-5% interest, that's pretty good so I think it's okay to pay those off over time.It sounds like you're making good income with your current employer and there is room to grow, so I'd plan to stay with that job until you can pay your high interest loans off and save enough for a down payment for your first property.

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.

That would be what I would profit on a build job, then the interest and closing costs and such would be paid by the person hiring me. 

I want to scale, but not sure how to develop my strategy.I have a $200k HELOC and excellent credit worthiness and high income from my day job.

Even tough, I am in information overload right now and working a full-time job at night.

Great job.

Avoid.The majority of the Mexican developers are honest and do a great job but people need to do a proper due diligence, including knowing who they're dealing with.

Any advise on adding washer/dryers is a plus I know routing new drains can be tricky when trying not to get to invasive on a "cosmetic" job.
